Answer:

f(x) = y

Step-by-step explanation:

a function just shows you that f(x) = y and the x in brackets isn't supposd to be multipled by f but rather it shows you what x will be. In this case y=25(4)+75.

Look at the figure. What is the value of x

arlik [135]

This triangle is isosceles (indicated by the tick marks), which means its base angles are congruent; given this, you can set them equal to each other to solve for x:

3x = 5x - 30
-2x = -30
x = 15

Answer:
x = 15

Hope this helps!

The six faces of a cube are painted black. The cube is then cut into <img src="https://tex.z-dn.net/?f=5%5E3%20%3D%20125" id="Te

Rasek [7]

Answer:

The probability that a randomly selected small cube is rolled and the face on the top is black is P=0.2.

Step-by-step explanation:

We have a cube, with the faces painted black, that each side is divided in 5, so we end up with 125 cubes.

We have to calculate the probability that a randomly selected cube is rolled and the face on the top is black.

This probability is equal to the proportion of black area in the total area of the cube.

We can define the side of the original cube as A=5a, being a the side of the small cubes.

The area that is painted black is equal to the sum of 6 squares of side A. In terms of a, that is:

$S_b=6\cdot A^2=6\cdot(5a)^2=6\cdot25a^2=150a^2$

The total area of the 125 small cubes is:

$S=125(6a^2)=750a^2$

Then, the ratio of black surface to the total surface is:

$s_b/s=(150a^2)/(750a^2)=0.2$

Then, we can conclude that the probability that a randomly selected small cube is rolled and the face on the top is black is P=0.2.

On a coordinate plane, a curved line with a minimum value of (negative 2.5, negative 12) and a maximum value of (0, negative 3)

alekssr [168]

The points on the graph of (-4, 0), (-2.5, -12), and (0, -3), gives;

F(x) > 0 over the interval (-∞, -4)

<h3>Which method can be used to find the true statement?</h3>

From the description of the graph, we have;

Furthest point left of the graph = (-4, 0)

The furthest point right on the graph = (0, -3) = The maximum point

The minimum point = (-2.5, -12)

F(x) < 0 at the minimum point

The minimum point is to the right of x = -4

The point the graph crosses the y-axis = (0, -3)

Therefore;

The interval of the graph where F(x) is larger than 0 is to the left of (-4, 0), is the interval (-∞, -4)

The true statement is therefore;

F(x) > 0 over the interval (-∞, -4)

What is the area of this figure?

Ugo [173]

Answer:

11610

Step-by-step explanation:

First you do the top rectangle which the area for that is 144 which is 4 times 4 times 3 times 3.

Then you do the middle rectangle which the area is 441 which is 7 times 7 times 3 times 3.

Then you do the last rectangle which the area is 11025 which is 15 times 15 times 7 times 7.

Then lastly you add all three areas which is 144+441+11025=11610. So therefore, the answer is 11610.
