The x-intercept of the function  f(x) = x² - 16x + 64 is x = 8.

The x-intercept of the graph can be found as follows:

f(x) = x² - 16x + 64

The x-intercept is the point at which the graph of an equation crosses the x-axis. In other words, the x-intercept is where a line crosses the x-axis on a graph.

The x-intercept is the value of x when y = 0.

Therefore,

x² - 16x + 64 = 0

Let's factorise

x² - 8x - 8x + 64 = 0

x(x - 8) -8(x - 8) = 0

Therefore,

(x - 8)(x - 8) = 0

Therefore,

x = 8

Answer:

6. 12cm

7. 11.2 cm

8. 92 degrees

9. 53 degrees

10. 37.5 cm

11. $ 693.12

Step-by-step explanation:

For questions 6-9 the triangle is congurent which means both their angles will be equal.

For the sides you can see that the second triangle is 1.5 times smaller than the first one as taking one of the sides 21/14= 1.5

So for Q. 6 we can multiply side PQ by 1.5.

For Q.7 divide CA by 1.5.

For Q. 10 we can do cross multiplication:

5/4 = x/30

= 150= 4x

= 37.5=x

For Q 11 we can see the size of the paper is 1.9 times bigger than the original one (38/20)

So the shorter side is 30.4 cm.

Then we have to find the area of the paper to multiply the two dimensions and we get 1155.2 square inches.

Then to figure out the money we multiply again and we get $693.12.

Given:

Base length of triangle = 40 units

Height of triangle = 9 units

Length of hypotenuse of triangle = 41 units

To find:

Find the value of Tan A

Steps:

Tan of an angle is equal to the opposite length by adjacent length.

So,

Tan A = \(\frac{opposite}{adjacent}\)

Tan A = \(\frac{9}{40}\)

Tan A = 0.225

Therefore, the exact value of Tan A is 0.225.

The average change in distance for each increase of 1 in the iron number is -10, and the y-intercept of the graphs are not the same

From the graph, we have the following points:

(x,y) = (4, 145) and (3,155)

The average change in distance is calculated using:

\(m = \frac{y_2 - y_1}{x_2 -x_1}\)

So, we have:

\(m = \frac{155 - 145}{3 - 4}\)

Evaluate

m = -10

Hence, the average change in distance for each increase of 1 in the iron number is -10

The rate, -10 in (a) means that:

Step-by-step explanation:

FV = 2500 e^(.05 * 3) = 2904.59

Since the volume of the pool is 948.98 gallons gallons and the garden hose can fill 720 gallons in half an hour, it is clear that Ines cannot fill the pool completely before her brother gets home in half an hour.

To determine if Ines has enough time to fill the pool before her brother gets home, we need to calculate the volume of the pool and the amount of water that the garden hose can fill in the given time.

The pool is cylindrical with an outer diameter of 9 ft and a height of 3 ft, which means the radius of the pool is 4.5 ft (half the diameter).

The width of the pool is given as 10 inches, which is 10/12 = 0.83 ft

radius of inner pool = 4.5-0.83 = 3.67 ft

The volume of the pool can be calculated using the formula for the volume of a cylinder:

\(V_{pool} = \pi r^2h\)

where π is approximately 3.14, r is the radius, and h is the height.

Substituting the given values, we get:

\(V_{pool} = 3.14 * (3.67)^2 * 3\)

\(V_{pool} = 126.87 ft^3\)

To convert this volume to gallons, we need to multiply by the conversion factor of 7.48 gallons per cubic foot:

\(V_{pool} = 126.87 * 7.48\)

\(V_{pool }= 948.98 gallons\)

Now we need to determine how much water the garden hose can fill in half an hour, which is 0.5 hours.

The flow rate of the garden hose is given as 24 gallons per minute, so in half an hour it can fill:

24 gallons/min * 30 min = 720 gallons

Since the volume of the pool is 948.98 gallons gallons and the garden hose can fill 720 gallons in half an hour, it is clear that Ines cannot fill the pool completely before her brother gets home in half an hour.

A description which best compares the graphs of the two functions above include the following: B. The line for function A is steeper.

In order to compare the two functions, we would have to find the slope of function B based on the data points contained in the table by using the slope formula.

Mathematically, the slope of a straight line can be calculated by using this formula;

Slope, m = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Slope, m = (y₂ - y₁)/(x₂ - x₁)

Substituting the given points into the slope formula, we have the following;

Slope, m = (-1 - (-2))/(3 - 0)

Slope, m = (-1 + 2)/3

Slope, m =1/3

From function A y = 3x - 2, the slope is equal to 3. Consequently, we can logically deduce that the line representing function A is steeper than the line representing function B because its slope is bigger i.e 3 > 1/3.

The triangle which are similar to ABC are:

The connecting of three non-collinear points results in a triangle, which is a three-sided closed-plane object. Triangles can be classified into three categories based on their side properties: equilateral, scalene, and isosceles.

We know that the when we sum all the interior angles of a triangle, we get 180°.

Given that, A triangle ABC has ∠A = 35° and ∠B = 20°.

∴ ∠C = 180° - 35° - 20°.

∠C = 125°.

Triangle will be similar if every corresponding angle of different triangles has the same measure. So, Triangles that are similar to triangle ABC is triangle DEF where ∠D is 35° and ∠E is 20° and triangle JKL where ∠J is 35° and ∠L is 125° and triangle MNO where ∠N is 20° and ∠O is 125°.

The average value of f(x, y, z) = z over the region bounded below by the xy-plane, on the sides by the sphere \(x^2 + y^2 + z^2\) = 81, and bounded above by the cone z = \(\sqrt{(x^2 + y^2)}\) is 0.

To find the average value of a function f(x, y, z) = z over the given region, we first define the boundaries. The region is bounded below by the xy-plane, meaning all points have z = 0.

It is bounded on the sides by the sphere \(x^2 + y^2 + z^2\) = 81, which represents a solid sphere centered at the origin with a radius of 9. Finally, it is bounded above by the cone z = √\(\sqrt{(x^2 + y^2)}\), where the height of the cone is equal to the distance from the origin.

To calculate the average value, we need to find the volume of the region and compute the triple integral of f(x, y, z) = z over that volume.

However, since the function f(x, y, z) = z is an odd function with respect to z and the region is symmetric, the positive and negative contributions of z will cancel each other out, resulting in an average value of 0.

The radius of the spherical part is 3 inches and the length of the tube is 21 cm.

The capacity of a cylinder, which determines how much material it can hold, is determined by the cylinder's volume. There is a formula for the volume of a cylinder that is used in geometry to determine how much of any quantity, whether liquid or solid, can be immersed in it uniformly.

Given that the volume when the water is fully dipped is 4554 / 7 cm³. The volume when the length is 9 cm empty is 396 cm³.

The two equations can be formed as below:-

4554 / 7 = πr²l + (2/3)πr³

396 = πr²( l - 9 ) + (2/3)πr³

Subtract the second equation from the first,

( 4554 / 7 ) - 396 = 9πr²

9πr² = 254.5

r² = 9

r = 3 cm

The length will be calculated as:-

4554 / 7 = πr²l + (2/3)πr³

4554 / 7 = π( 3 )²l + (2/3)π(3)³

l = 21 cm

Given that :

A street light is at the top of a pole that has a height of 15 ft.

Height of the pole = 15 feet

Height of the woman = 4 feet

The speed at that the woman walks = 7 feet per second.

Let x be the distance of the woman from the pole and y be the distance from the shadow tip of the woman to the pole.

We get two similar triangles.

Using the similarity rule :

(y - x) / y = 4 / 15

15(y - x) = 4y

15y- 15x = 4y

11y = 15x

y = 15/11 x

Differentiating on both sides :

dy/dt = 15/11 dx/dt

Step-by-step explanation:

We are given the following system:

x + y = 7

5x - y = 5

We want to solve it by elimination. To do that, we will add or subtract the equations together to clear one of the variables, solve for the other variable, and then plug the value of the variable found to find the value of the other variable.

Before we eliminate, we need to have one of the variables have the same coefficient, but with opposite signs - we can see that is the case with the y's, so we can add the two equations together.

Add the 2 equations together.

x + y = 7

5x - y = 5

___________

6x = 12

Divide both sides by 6.

6x = 12

÷6    ÷6

___________

x = 2

Now, substitute 2 as x in either x + y = 7 or 5x - y = 5

Taking x + y = 7 for instance,

2 + y = 7

Subtract 2 from both sides.

y = 5

The answer is x = 2, y = 5. As a point, it is (2,5).
