Tanzania [10]3 years ago

Answer:

C

Step-by-step explanation:

If you simplify the equation you get $\sqrt{\frac{x+3}{1-x} }$ . To solve a square root function, you need to set up $\sqrt{\frac{x+3}{1-x} }\geq 0$ . You can take the square root of both sides to get $\frac{x+3}{1-x} \geq 0$ . Then, we identify the intervals that will satisfy the equation, which is -3 ≤ x < 1.

Sorry if the explanation is kind of confusing, I wasn't sure how to describe it.

a) <u>n² + 6 </u>

~Here n is the number of term. So, put n = 1,2,3,4.... to get the term.

If n = 1, first term = 1² + 6 = 7
n = 2, second term = 10
n = 3, third temm = 15
n = 4, fourth term = 22
n = 10, tenth term = 106

b) <u>3n²</u>

If n = 1, first term = 3
n = 2, second term = 12
n = 3, third term = 27
n = 4, fourth term = 48
n = 10, tenth term = 300

Find the center of the circle (x-2)^2+(y-8)^2=33

enyata [817]

Answer:

The center is (2,8)

Step-by-step explanation:

The equation of a circle is written as

(x-h)^2+ (y-k)^2 = r^2

where ( h,k) is the center and r is the radius

(x-2)^2+(y-8)^2=33

The center is (2,8) and the radius is sqrt(33)

Trevor is making 2/3 of a recipe for chicken noodle soup. He adds ½ cup of chopped celery. The equation 2/3 c = 1/2 can be used

Nikitich [7]

Answer:

Cups of chopped celery in original recipe = $\frac{3}{4}\ cups$

Step-by-step explanation:

Given that:

Trevor is making 2/3 of a recipe

Number of cups of chopped celery used = 1/2 cup

The following equation can be used to find the original number of cups of chopped celery used in recipe.

$\frac{2}{3}c=\frac{1}{2}$

Multiplying both sides by 3/2

$\frac{3}{2}*\frac{2}{3}c=\frac{1}{2}*\frac{3}{2}\\\\c= \frac{3}{4}\\$

Hence,

Cups of chopped celery in original recipe = $\frac{3}{4}\ cups$
