Answer:

Step-by-step explanation:

So they are showing you a chart in which the column y is determined by the column x, so you divide y/x in any of the rows so that you get the relation.

100/4=25 (which is the same for every row)

It works pretty much the same for the graph, but the relation is different.

Now instead of a chart you have to figure out the values of x and y by looking at the points that make up the line. For example we have a point that is in the coordinate (2, 60), and that represents that the x value is 2 and its correspondent y is 60. And to find the relation we do it as in the first step but now with 2 and 60.

60/2=30 (which is the same for every point)

Finally we just calculate the value of y both in the graph and the chart when x=12

So for the chart: 12*25= 300

And for the graph: 12*30= 360

The difference between those two is 60.

Question : In the given figure , ∆ APB and ∆ AQC are equilateral triangles. Prove that PC = BQ.

lorasvet [3.4K]

Answer:

See Below.

Step-by-step explanation:

We are given that ΔAPB and ΔAQC are equilateral triangles.

And we want to prove that PC = BQ.

Since ΔAPB and ΔAQC are equilateral triangles, this means that:

$PA\cong AB\cong BP\text{ and } QA\cong AC\cong CQ$

Likewise:

$\angle P\cong \angle PAB\cong \angle ABP\cong Q\cong \angle QAC\cong\angle ACQ$

Since they all measure 60°.

Note that ∠PAC is the addition of the angles ∠PAB and ∠BAC. So:

$m\angle PAC=m\angle PAB+m\angle BAC$

Likewise:

$m\angle QAB=m\angle QAC+m\angle BAC$

Since ∠QAC ≅ ∠PAB:

$m\angle PAC=m\angle QAC+m\angle BAC$

And by substitution:

$m\angle PAC=m\angle QAB$

Thus:

$\angle PAC\cong \angle QAB$

Then by SAS Congruence:

$\Delta PAC\cong \Delta BAQ$

And by CPCTC:

$PC\cong BQ$

What is the volume of a come that has a height of 40 millimeters and a diameter of 25 millimeters? Use 3.14 for pi.

Fantom [35]

Answer:

6541.7 mm³ (nearest tenth)

Step-by-step explanation:

$\boxed{volume \: of \: cone = \frac{1}{3}\pi {r}^{2}h }$

Given that the height is 40mm, h= 40mm.

Diameter= 2(radius)

Radius of cone

= 25 ÷2

= 12.5mm

Volume of cone

$= \frac{1}{3} (3.14)(12.5)^{2} (40)$

= 6541.7 mm³ (nearest tenth)

A quadratic function f(x)=ax2 passes through (0,0) and (5,5). write an equation for this function

krek1111 [17]

Answer:

y = (1/5)x² or y = x²/5

Step-by-step explanation:

We have the function f(x) = ax² and are given that the point (5,5) is on the parabola. We need to find 'a'. f(x) can be replaced with 'y', so we can rewrite the equation as...

y = ax²

We know that when x = 5, y = 5, so we have

5 = a(5²) now simplify...

5 = 25a

5/25 = a

1/5 = a, so our equation becomes

(1/5)x² or x²/5 (the expressions are equal)

Suppose the function h(x)=2x-9 is translated up 5 united to become a new function, i(x). what the equation of the new function?

andreyandreev [35.5K]

Option B

i(x) = 2x - 4 is the equation of the new function

Solution:

Given that the function h(x) = 2x-9 is translated up 5 united to become a new function, i(x)

To find: Equation of new function

The graph of a function can be moved up, down, left, or right by adding to or subtracting from the output or the input.

Adding to the output of a function moves the graph up

Therefore,

Given function is:

h(x) = 2x - 9

Translated up by 5 units

Therefore, new function is:

i(x) = h(x) + 5

i(x) = 2x - 9 + 5

i(x) = 2x - 4

Thus Option B is correct
