Vertices: (4,13) and (4,3) Foci: (4,11)and (4,5) Write a equation

just olya [345]

Answer:

(x-4)²/16 + (y-8)²/25 = 1

Step-by-step explanation:

center (h,k): ((4+4)/2 , (3+13)/2) = (4 , 8)

a = 13-8 = 5 c = 8-5 = 3

b = √5²-3² = 4

Equation: (x-h)²/b² + (y-k)²/a² = 1

(x-4)²/16 + (y-8)²/25 = 1

If -3m + 1 > 7, which of the following is a solution set for m?

Papessa [141]

ANSWER

m < -2

EXPLANATION

We want to find the solution set for m in:

$-3m+1>7$

First, collect like terms:

$\begin{gathered} -3m>7-1 \\ -3m>6 \end{gathered}$

Now, divide both sides by -3. When you divide an inequality by a negative number, the sign changes direction:

$\begin{gathered} \frac{-3m}{-3}>\frac{6}{-3} \\ m$

This means that all values of m must be less than -2.

None of the options contains the correct solution set.

Perimeter, Area And Volume

san4es73 [151]

Answer:

A ≈ 1900.7 m²

Step-by-step explanation:

The area (A) of the race track is

area of outer circle - area of inner circle

= πR² - πr²

= π × 63² - π × 58²

= π (63² - 58² )

= π(3969 - 3364)

= π × 605

≈ 1900.7 m² ( to 1 dec. place )

What is 2 5/8 - 2 3/12?

Marianna [84]

Answer:

9/24

Step-by-step explanation:

First, find the LCD: 24.

24/8=3. 3*5=15. So, 2 5/8 becomes 2 15/24.

24/12=2. 2*3=6. So, 2 3/12 becomes 2 6/24.

2 15/24 - 2 6/24 = 9/24.
