Answer:

What will help is labeling the diagram with the given info..A proof always ends with the statement you have to prove.

Step-by-step explanation:

STATEMENT..............REASON

1) ∠F≅∠C 1) Given

2) E is the midpoint of GD 2) Given

3) GE≅ED 3) If a point is a midpoint then 2 ≅ segments are formed

4) FE≅EC 4) Same as 3

5)∠G≅∠D 5)

6) FG≅CD 6)

I tried my best with step 5 and 6..but you know step 6 has to be the prove statement but i don't know what the reason would be. I hope i helped a bit though.

A coordinate plane with a line passing through the points (negative 4, negative 5) and (1, negative 1).

Ksju [112]

Answer:

4x - 5y - 9 = 0

$\frac{9}{4}$

$\frac{-9}{5}$

Step-by-step explanation:

The equation of a straight line passing through the points (-4,-5) and (1,-1) is given by $\frac{y - (-5)}{-5-(-1)} =\frac{x-(-4)}{-4-1}$

⇒ $\frac{y+5}{-4} =\frac{x+4}{-5}$

⇒ 5y + 25 = 4x + 16

⇒ 4x - 5y - 9 = 0 ....(1) (Answer)

Now, this above equation can be represented as

$\frac{x}{\frac{9}{4} } + \frac{y}{\frac{-9}{5} } =1$

Therefore, the x-intercept is $\frac{9}{4}$ (Answer)

And the y-intercept is $\frac{-9}{5}$ . (Answer)

What is the volume of a hemisphere with a diameter of 51.8 inches rounded to the nearest 10th of a cubic inch?

lorasvet [3.4K]

Answer:

volume of a hemisphere ≈ 36369.5 in³

Step-by-step explanation:

To find the formula for calculating the volume of a hemisphere, we will follow the steps below:

write the formula for calculating the volume of a hemisphere.

volume of a hemisphere = volume of a sphere ÷2

= $\frac{4}{3}$ πr³ ÷ 2

= $\frac{2}{3}$ πr³

where r is the radius

from the question given, diameter = 51.8 inches

but diameter = 2r , this implies that r = $\frac{d}{2}$ hence r = $\frac{51.8}{2}$ = 25.9 inches

π is a constant and is ≈ 3.14

we can now proceed to insert the values into the formula

volume of a hemisphere = $\frac{2}{3}$ πr³

= $\frac{2}{3}$ × 3.14 ×25.9³

= $\frac{2}{3}$ × 3.14×17373.979

≈36369.5 in³ to the nearest tenth cubic inch.

volume of a hemisphere ≈ 36369.5 in³
