The required diameter of the sphere for the given volume of the sphere is equal to 12.2 cm (rounded to one decimal place)

Volume of the sphere = 944cm^3

Let us consider V be the volume of the sphere.

And r be the radius of the sphere.

The formula for the volume of a sphere is,

V = (4/3) × π × r^3

Solve for the radius of the sphere by rearranging the formula as follows,

⇒ r^3 = (3/4) × (V/π)

⇒r = [(3/4)×(V/π)]^(1/3)

Substituting V = 944 cm^3, we have,

⇒ r = [(3/4) ⇒ (944/π)]^(1/3)

⇒r ≈ 6.08 cm

⇒r ≈ 6.1 cm (rounded to one decimal place)

The diameter of the sphere is twice the radius, so the diameter is,

d = 2r

   ≈ 12.2 cm (rounded to one decimal place)

Therefore, the diameter of the sphere with a volume of 944 cm^3 to the nearest tenth of a centimeter is 12.2 cm.

The boundary line of the inequality y < (1/3)x + 1 is the equation y = (1/3)x + 1 with a dashed line because the inequality does not include the line itself.

To graph this line, we can start by plotting the y-intercept, which is the point (0, 1). From there, we can use the slope of 1/3 to find additional points on the line. For example, if we move 3 units to the right (increasing x by 3), we move up 1 unit (increasing y by 1), so we can plot the point (3, 2). Similarly, if we move 3 units to the left (decreasing x by 3), we move down 1 unit (decreasing y by 1), so we can plot the point (-3, 0).

Using these points, we can draw a dashed line through them to represent the boundary line of the inequality:

      |

   3  |         *

       |      *    

   2  |   *

       |*      

   1  |  

       |

   0  | *    

       |

       ---------------

          -3   0   3   6   x

The correct graph showing the boundary line of y < (1/3)x + 1 is the one with a dashed line passing through the points (0, 1), (3, 2), and (-3, 0), as shown above.

The curve passes through the point (3, 3), so \(y=3\) when \(x=3\). Then

\(y = ax^2 + bx \implies 3 = 9a + 3b \implies 3a + b = 1\)

The tangent line to the curve at (3, 3) has gradient \(\frac{dy}{dx}\) at \(x=3\). Compute the derivative.

\(y = ax^2 + bx \implies \dfrac{dy}{dx} = 2ax + b\)

Then when \(x=3\), the gradient is 4, so

\(2ax + b = 4 \implies 6a+b=4\)

Solve for \(a\) and \(b\). Eliminating \(b\), we find

\((6a+b) - (3a+b) = 4-1 \implies 3a = 3 \implies \boxed{a=1}\)

Answer:

Equation: X × 0.4 + (10 - X)×0.05 = 10 × 0.2

Solution: 5.71 liters of 5% and 4.29 liters 40%

Step-by-step explanation:

The volume of the 20% acid solution the scientist needs = 10 liters

The concentration of the solution she has = 5% and 40%

Therefore, we have;

X volume of the 40% solution is mixed with 10 - X volume of the 5% solution, to obtain 10 liters of the 20% solution

Therefore, we have;

Equation: X × 0.4 + (10 - X)×0.05 = 10 × 0.2

0.4·X + 0.5 - 0.05·X = 2

0.35·X = 2 - 0.5 = 1.5

X = 1.5/0.35 = 30/7

∴ The volume of the 40% solution = 30/7 liters ≈ 4.29 liters

The volume of the 5% solution = 10 - X = 10 - 30/7 = 40/7 liters ≈ 5.71 liters

Therefore, we have;

5.71 liters of 5% solution and 4.29 liters 40% solution.

Step-by-step explanation:

To find the volume of this solid, we will use the method of cylindrical shells. We will integrate the cross-sectional area of a cylinder, given by πr^2, over the height of the solid. The height of the solid is given by the difference between the upper and lower bounds of the region, which are y = x^2 and y = 0, respectively. The radius of each cylindrical shell is given by the distance of the cross-sectional circle from the y-axis, which is x.

So, the volume of the solid is given by the integral:

V = ∫[0, 1] π * x^2 dx

Using the antiderivative of π * x^2, which is π * x^3 / 3, we can find the definite integral:

V = (π * x^3)/3 from 0 to 1

Evaluating the definite integral and simplifying, we get:

V = π/3 units^3

So, the volume of the solid is π/3 units^3.

The number of weeks are 0 1 2 4 7 12

The balances are 24 32 40 56 80 120

The rate of change of the balance of the student's savings account in dollars and cents per week is also referred to as the slope of the graph that can be potted with these values. The formula for slope is expressed as

Slope = (y2 - y1)/(x2 - x1)

y1 and y2 would be consecutive values of the balance

x1 and x2 would be consecutive values of the number of weeks

When x1 = 0, y1 = 24

When x2 = 1, y1 = 32

Slope = (32 - 24)/(1 - 0)

Slope = 8

(a)The amount of water in the tank is increasing.

(b)Evaluate  \(\int\limits^{18}_0(W(t) - R(t)) dt\) to get the number of gallons of water in the tank at t = 18.

(c)Solve part (b) to get the absolute minimum from the critical points.

(d)The equation can be set up as   \(\int\limits^k_{18}-R(t) dt = 1200\) and solve this equation to find the value of k.

What is the absolute value of a number?

The absolute value of a number is its distance from zero on the number line. It represents the magnitude or size of a real number without considering its sign.

To solve the given problems, we need to integrate the given rates of water flow to determine the amount of water in the tank at various times. Let's go through each part step by step:

a)To determine if the amount of water in the tank is increasing at time t = 15, we need to compare the rate of water being pumped in with the rate of water being removed.

At t = 15, the rate of water being pumped in is given by \(W(t) = 95Vt sin^2(\frac{t}{6})\) gallons per hour. The rate of water being removed is \(R(t) = 275 sin^2(\frac{1}{3})\) gallons per hour.

Evaluate both rates at t = 15 and compare them. If the rate of water being pumped in is greater than the rate of water being removed, then the amount of water in the tank is increasing. Otherwise, it is decreasing.

b) To find the number of gallons of water in the tank at time t = 18, we need to integrate the net rate of water flow from t = 0 to t = 18. The net rate of water flow is given by the difference between the rate of water being pumped in and the rate of water being removed. So the integral to find the total amount of water in the tank at t = 18 is:

\(\int\limits^{18}_0(W(t) - R(t)) dt\)

Evaluate this integral to get the number of gallons of water in the tank at t = 18.

c)To find the time t when the amount of water in the tank is at an absolute minimum, we need to find the minimum of the function that represents the total amount of water in the tank. The total amount of water in the tank is obtained by integrating the net rate of water flow over the interval [0, 18] as mentioned in part b. Find the critical points and determine the absolute minimum from those points.

d. For t > 18, no water is pumped into the tank, but water continues to be removed at the rate R(t) until the tank becomes empty. To find the value of k, we need to set up an equation involving an integral expression that represents the remaining water in the tank after time t = 18. This equation will represent the condition for the tank to become empty.

The equation can be set up as:

\(\int\limits^k_{18}-R(t) dt = 1200\)

Here, k represents the time at which the tank becomes empty, and the integral represents the cumulative removal of water from t = 18 to t = k. Solve this equation to find the value of k.

The alternative hypothesis would be: The proportion of people who own cats is smaller than 90%.

The null hypothesis for this test would be: The proportion of people who own cats is equal to or greater than 90%.

To conduct the hypothesis test, we would need to collect a random sample of 1400 individuals and determine how many of them own cats. Based on this information, we could calculate the sample proportion of cat owners and use this to test the claim that the population proportion is smaller than 90%.

We would use a one-tailed hypothesis test with a significance level of 0.005. If the p-value for our test is less than 0.005, we would reject the null hypothesis and conclude that there is sufficient evidence to support the alternative hypothesis that the proportion of people who own cats is smaller than 90%.
Hi! I'd be happy to help you with this question. You want to test the claim that the proportion of people who own cats is smaller than 90% at the 0.005 significance level.

To do this, we will set up our null and alternative hypotheses as follows:

Null Hypothesis (H0): The proportion of people who own cats is equal to 90% (p = 0.90)
Alternative Hypothesis (H1): The proportion of people who own cats is smaller than 90% (p < 0.90)

Here's a step-by-step explanation of how to test this claim:

1. Determine the sample size (n) and the number of cat owners in the sample (x): In this case, n = 1400, and x = 615.

2. Calculate the sample proportion (p-hat): p-hat = x/n = 615/1400 ≈ 0.439.

3. Determine the significance level (alpha): In this case, alpha = 0.005.

4. Calculate the standard error (SE) of the sample proportion: SE = sqrt[p*(1-p)/n] = sqrt[0.9*(1-0.9)/1400] ≈ 0.008.

5. Calculate the z-score: z = (p-hat - p)/SE = (0.439 - 0.9)/0.008 ≈ -57.63.

6. Find the critical z-value for a one-tailed test at the 0.005 significance level: z-critical = -2.576 (from a standard normal distribution table).

7. Compare the calculated z-score with the critical z-value: Since the calculated z-score (-57.63) is less than the critical z-value (-2.576), we reject the null hypothesis.

In conclusion, based on this analysis, we have enough evidence to support the alternative hypothesis that the proportion of people who own cats is smaller than 90% at the 0.005 significance level.
