Answer:

"Eduardo did not use the correct formula for the circumference"

Step-by-step explanation:

The circumference formula is C = 2πr

Area formula is A=πr^2

Volume formula is correct. The steps area also correct to find r, the radius.

But in the end, he put the formula for circumference wrong. He used the formula for Area, NOT Circumference.

Hence, "Eduardo did not use the correct formula for the circumference" should be the correct choice for this question.

Which Postulate/Theorem below would prove that the triangles shown below are congruent?

velikii [3]

Answer:

Correct answer is D. ASA

Step-by-step explanation:

Let us first define ASA congruence rule:

2 triangles are called congruent according to ASA congruence rule if 2 angles of the triangle and the corresponding side between these two angles are equal to each other.

In the question figure, we can figure out following conclusions from Triangles $\triangle SRT\text{ and }\triangle WXY$ respectively:

$\angle TRS = \angle YXW$
Side RS = Side WX
$\angle TSR = \angle YWX$

As per the definition of option d) ASA congruence, the triangles are congruent.

Write an equation of the line that passes through the point (5,-4) and has a slope of 2.

Romashka-Z-Leto [24]

Answer:

Point slope formula: (y + 4) = 2(x - 5)

Slope intercept formula: y = 2x - 14

Step-by-step explanation:

Point slope formula: (y + 4) = 2(x - 5)

Slope intercept formula: y = 2x + b, -4 = 10 + b, b = -14

y = 2x - 14
