-2 + 4 is 2 4+ -6 is -2

Answer:

the answer is 2/9

Step-by-step explanation:

1/6 ÷ 3/4

= 1/6 × 4/3

= 4/18

= 2/9

Answer:

The answer is B

Step-by-step explanation:

These are triangles are similar and because of that:

x/6 = (x+2.5)/(6+4)

x/6 = x/10 + 0.25

x = 6x/10 + 1.5

4x/10 = 1.5

4x = 15

x = 3.75

Answer:

5 + 2(3 + 2x) = x + 3(x + 1) has no solutions.

Step-by-step explanation:

Let's solve your equation step-by-step.

5+2(3+2x)=x+3(x+1)

Simplify both sides of the equation.

5+2(3+2x)=x+3(x+1)

5+(2)(3)+(2)(2x)=x+(3)(x)+(3)(1) (you distribute here)

5+6+4x=x+3x+3

(4x)+(5+6)=(x+3x)+(3)(Combine Like Terms)

4x+11=4x+3

4x+11=4x+3

Subtract 4x from both sides.

4x+11−4x=4x+3−4x

11=3

Subtract 11 from both sides.

11−11=3−11

0 = −8

so there are no solutions because 0 does not equal -8.

Answer:the second question has no solution

Step-by-step explanation:

expand 3 (x + 1): 3x + 3

4x+11=x+3x+3

add similar elements: x + 3 x = 4x 

expand 5  2(3 2x): 4x

add similar elements: x + 3x = 4x

expand 5 + 2 (3 + 2x) 4x + 11

4x + 11-11 = 4x + 3-11

 subtract 11 from both sides

 4x + 11-11 = 4x + 3-11

 Simplify

4x=4x-8

subtract 4x from both sides

 4x-4x=4x-8-4x

Simplify

0=-8

the sides are not the same

Step-by-step explanation:

The values that complete the table are -1/2, -√2/2 and -√3/2

The function is given as:

\(y = sin(x)\)

From the table, we have:

sin(π) = 0

Next, we calculate the value of y for other values of x

When x = 7π/6, we have:

sin(7π/6) = -1/2

When x = 5π/4, we have:

sin(7π/6) = -√2/2

When x = 4π/3, we have:

sin(4π/3) = -√3/2

Hence, the values that complete the table are -1/2, -√2/2 and -√3/2

At most, they can wash 96 cars and mow 96 lawns.

To determine the maximum number of cars they can wash and lawns they can mow, we need to consider the work rates of each person and the total number of hours they work.

Huey can wash 6 cars or mow 3 lawns in one hour, so in 8 hours, he can wash 6 \(\times\) 8 = 48 cars or mow 3 \(\times\) 8 = 24 lawns.

Dewey can wash 3 cars or mow 3 lawns in one hour, so in 8 hours, he can wash 3 \(\times\) 8 = 24 cars or mow 3 \(\times\) 8 = 24 lawns.

Louie can wash 3 cars or mow 6 lawns in one hour, so in 8 hours, he can wash 3 \(\times\) 8 = 24 cars or mow 6 \(\times\) 8 = 48 lawns.

Since two of them wash cars and one mows lawns, the maximum number of cars they can wash is the sum of the maximum cars each person can wash, which is 48 + 24 + 24 = 96 cars.

The maximum number of lawns they can mow is the sum of the maximum lawns each person can mow, which is 24 + 24 + 48 = 96 lawns.

The value of P(1.41 < Z < 2.85)  is 0.0771.

Hence, the correct answer is d.

A normally distributed random variable with mean μ= 0 and standard deviation σ= 1 is referred to as a standard normal random variable. The letter Z will always be used to represent it.

Because the Standard Normal Distribution is a probability distribution, the area under the curve between two points indicates the likelihood that variables will take on a range of values.

The whole area under the curve is one, or one hundred percent.

The mean and variance of a normal distribution are governed by two factors.

A standard normal distribution is a normal distribution with a mean of 0 and a standard deviation of 1.

The probability that a standard normal random variable Z is between 1.41 and 2.85 can be found using a standard normal table with a standard normal cumulative distribution function.

The answer is approximate:

P(1.41 < Z < 2.85)

= P(Z < 2.85) - P(Z < 1.41)

= 0.9927 - 0.9185

= 0.0742

Isabel is incorrect because the point of intersection between line B and parabola A that can be determined is the y-intercept of the equations, not the vertex.  This can be obtained using finding y intercept of both parabolas and vertex of parabola A.

Parabola A, (x + 3)² = y = x² + 6x + 9

Parabola B, y = mx + 9

x=0, y = 9

y coordinate of parabola A is (0,9)

⇒The vertex coordinate,

(-b/2a , -(b²-4ac)/4a) = (-3,0)          

x=0, y = 9  

y coordinate of parabola B is (0,9)

The perimeter of the entire shape that is made up of a semi circle and an equilateral triangle would be = 116.66in

The perimeter of a shape is defined as the total area of all the sides surrounding that shape.

The perimeter of the object can be calculated by the addition of the perimeter of the triangle and the circle.

The perimeter of the triangle = a+b+c = 19+19+19 = 57in

The perimeter of the circle = 2πr

where π = 3.14

r = 19/2 = 9.5 in

perimeter = 2×3.14×9.5 = 59.66in

Weighted sum approach is a mathematical technique used to combine two or more values into a single, overall score.

It is used to assign weights to the different values to reflect their relative importance and then add the weighted values together to get the overall score.

The formula for weighted sum approach is: Overall Score = \((Weight1*Value1) + (Weight2*Value2) +…+(Weightn*Valuen)\). The weights should always add up to 1.

For example, if two criteria, A and B, were to be evaluated with weights of 0.6 and 0.4, respectively, the overall score could be calculated as: Overall Score =\((0.6*Value of A) + (0.4*Value of B).\)

Weighted sum approach is a useful tool for making decisions in situations where multiple criteria need to be taken into account. It can be used to compare different options and determine which one is the best overall.

The coordinates are:

To find the coordinates:

In Analytical Geometry, the midpoint of a line is calculated as the mean of two points, as follows:

\($$x_m=\frac{x_1+x_2}{2}, y_m=\frac{y_1+y_2}{2}$$\)

Each segment has two endpoints and two midpoints, which are as follows:

We must be cautious not to add the wrong coordinates.

In the first line A:

\($$\begin{aligned}&2=\frac{1+x_2}{2} \\&4=1+x_2 \\&4-1=-1+1+x_2 \\&x_2=3 \\&-1=\frac{y_2-9}{2} \\&-2=y_2-9 \\&+2-2=y_2-9+2 \\&y_2=-7\end{aligned}$$\)

So (3,7) is the other endpoint where the segment begins (1,-9).

The endpoint of the second line b at (-2,18) and its midpoint (5,9).

\($$\begin{aligned}&5=\frac{-2+x_2}{2} \\&10=-2+x_2 \\&+2+10=+2-2+x_2 \\&x_2=12 \\&9=\frac{18+y_2}{2} \\&18=18+y_2 \\&-18+18=-18+18+y_2 \\&y_2=0\end{aligned}$$\)

Answer:

x = 1.523

Step-by-step explanation:

Given
\(\quad\quad e^{x-1} = 3^{2-x}\)

we are asked to solve for x

Take natural logs on both sides:
\(\ln \left(e^{x-1}\right)=\ln \left(3^{2-x}\right)\\\\\mathrm{Apply\:log\:rule}:\quad \log _a\left(x^b\right)=b\cdot \log _a\left(x\right)}\\\\\ln \left(e^{x-1}\right)=\left(x-1\right)\ln \left(e\right)\\\\\rightarrow \left(x-1\right)\ln \left(e\right)=\ln \left(3^{2-x}\right)\)substitute on left side of original eqn

\(\ln \left(3^{2-x}\right)=\left(2-x\right)\ln \left(3\right)\\\\\)

Therefore we get
\(\left(x-1\right)\ln \left(e\right)=\left(2-x\right)\ln \left(3\right)\)

But ln(e) = 1

So we get
\(x - 1 = (2-x)\;\ln(3)\\\\\)

So the expression becomes

\(x - 1 = (2- x) \ln(3)\\\\x - 1 = 2\ln(3) - x \ln(3)\)

Add \(x\ln(3)\) on both sides:

x + x ln(3) - 1 = 2ln(3)

Add 1 to bot sides:
x + x ln(3) = 2ln(3) + 1

x(1 + ln(3)) = 2 ln3 + 1

ln(1 + \ln(3)) = 2.09861

2ln(3) + 1 =3.1972

So we get

x(2.0986) = 3.1972

x = 3.1972/2.0986 = 1.52349

Rounded to 3 decimal places, the answer is 1.523

The maximum and minimum values are 34.5 and 2

from the question, we have the following parameters that can be used in our computation:

P = 2x + 7y

Subject to:

4x - 2y <= 5

x >= 1

0 <= y <= 4

Next, we plot the constraints on a graph

From the graph, we have the following vertices

(1, 0), (4, 0) and (3.25, 4)

This gives

P = 2(1) + 7(0) = 2

P = 2(4) + 7(0) = 8
