Because the angles of both triangles are equal, they are similar triangles, and because they share side JL, they are congruent triangles. due to this, the length of side KJ=JM, therefore 2x-7=3x-16. solving this for x, we get that x=9. And because KJ=2x-7, plugging in 9 for x we get that KJ=11 m

Which line shows theINITIAL error in volume work?

aliina [53]

In step 2, V = $\frac{4}{3}(3.14)(37.5)$ show the error in volume work.

Solution:

Given data:

The steps shows it is sphere.

Radius of the sphere = 12.5

The value of π = 3.14

Volume of the sphere = $\frac{4}{3} \pi r^3$

Step 1:

$$V=\frac{4}{3} (3.14)(12.5)^3$

$$V=\frac{4}{3} (3.14)(12.5)(12.5)(12.5)$

Step 2:

$$V=\frac{4}{3} (3.14)(1953.125)$

Step 3:

$$V=\frac{4}{3} (6132.81)$

Step 4:

V = 8177.08 cubic units

This is the correct solution.

But in the given options, in step 2, 12.5 is multiplied by 3.

That is not the correct step. You have to do 12.5 × 12.5 × 12.5.

Hence in step 2, V = $\frac{4}{3}(3.14)(37.5)$ show the error in volume work.

PLEASE HELP ME!

kotegsom [21]

Answer:

Bottom left graph

Step-by-step explanation:

We have to use what is called the zero-interval test [test point] in order to figure out which portion of the graph these inequalities share:

−2x + y ≤ 4 >> Original Standard Equation

+ 2x + 2x

_________

y ≤ 2x + 4 >> Slope-Intercept Equation

−2[0] + 0 ≤ 4

0 ≤ 4 ☑ [We shade the part of the graph that CONTAINS THE ORIGIN, which is the right side.]

$\displaystyle y > x + 2 \\ \\ 0 ≯ 2$ [We shade the part of the graph that does not contain the origin, which is the left side.]

So, now that we got that all cleared up, we can tell that the graphs share a region in between each other and that they both have POSITIVE RATE OF CHANGES [SLOPES], therefore the bottom left graph matches what we want.

** By the way, you meant $\displaystyle y > x + 2$ because this inequality in each graph is a dashed line. It is ALWAYS significant that you be very cautious about which inequalities to choose when graphing. Inequalities can really trip some people up, so once again, please be very careful.

I am joyous to assist you anytime.
