Answer:

Second Option is correct that is the sum of the focal radii.

Step-by-step explanation:

Given: Ellipse

To find: Length of the Major Axis.

Focal Radii is the length of the line connecting the focus of ellipse and a point on the ellipse.

We know that Sum of Focal Radii is a constant and Equal to the Length of the Major Axis.

Therefore, Second Option is correct that is the sum of the focal radii.

Answer:

volume of hemisphere = 452.16 ft³

volume of cylinder = 2260.8 ft³

total volume = 2712.96 ft³

1/3 full = 904.32 ft³

Step-by-step explanation:

volume of hemisphere = 1/2(4/3)(3.14)(6³) = 452.16 ft³

volume of cylinder = (3.14)(6²)(20) = 2260.8 ft³

total volume = 452.16 + 2260.8 = 2712.96 ft³

1/3 full = 2712.96/3 = 904.32 ft³

Q(x)= 1/2x - 3; q(x) =-4. Find the value of x

Lelu [443]

Answer:

$q(x) =-5$

Step-by-step explanation:

I am solving this using Function Notation.

We are given:

$q(x)= \frac{1}{2}x - 3$

While we are to find:

$q(x) =-4$

In Function Notation, replace all the " $x$ " you see with the value you are given.

So, in this case,

$q(x)= \frac{1}{2}x - 3\\\\=\frac{1}{2}x - 3$

Would become

$q(x)= \frac{1}{2}x - 3\\\\=\frac{1}{2}(-4) - 3$

Now we can solve.

$\frac{1}{2}(-4) - 3$

Use PEMDAS; Parenthesis first;

$\frac{1}{2}(-\frac{4}{1})$

Cross divide: 1 cancels 1, -4 ÷ 2 = -2

Hence, we are left with

$(-2) - 3$

$-5$

Therefore, the value of x is -5

−−→ LO bisects ∠ NLM , LM = 18 , NO = 4 , and LN = 10 . LO → bisects ∠ NLM , LM = 18 , NO = 4 , and LN = 10 . What is the value

Sindrei [870]

Answer:

7.2

Step-by-step explanation:

Given that in triangle LMN, LO is angle bisector of angle L.

LN =10 and LM =18

By angle bisector theorem for triangles we have

LN/LM = NO/MO

Substitute the values for known things and x for MO

We get

10/18 = 4/x

Or cross multiply to get

10x=72

x=7.2

So answer is 7.2
