Answer:
[tex]y = \frac{1 }{8} {(x + 3)}^{2}[/tex]
Step-by-step explanation:
[tex]y = a(x - h)^{2} + k \\ y = a(x - ( - 3))^{2} + 0 \\ using \: points \: (1 ,\: 2) \\ 2 = a {(1 - ( - 3))}^{2} \\ 2 = a{4}^{2} \\ 16a = 2 \\ \boxed{ a = \frac{1}{8} } \\ hence \to \\ y = \frac{1}{8} (x - ( - 3))^{2} \\ y = \frac{{(x + 3)}^{2} }{8} [/tex]

The function c ( x ) = 63 ⋅ ( 1.03 ) x models the cost in dollars, c , of 1 ounce of a certain chemical used in a laboratory. x represents the number of years since 1990.
Does the cost of the chemical increase or decrease with time?
Group of answer choices
Increase
Decrease
Answers
9514 1404 393
Answer:
increase
Step-by-step explanation:
Your cost function appears to be an exponential function of the form ...
c(x) = (initial cost)·(growth factor)^x
When the growth factor (1.03) is greater than 1, it means the exponential function is increasing with x (time).
The cost function increases with time.

The number of planes in a year will be 219000 planes.
How to calculate the value in a year?Rate demonstrates how many times one number can fit into another number. Rate contrast two numbers by ordinarily dividing them. A/B will be the formula if one is comparing one data point (A) to another data point (B).
Here, 150 planes arrive in 6 hours. The number of planes in a day which is 24 hours will be:
= 150 × (24/6)
= 600 planes.
The planes in a year will be:
= 600 × 365
= 219000 planes.

What is the value of X in degrees?
A.13.8
B.16
C.20
D.24
Answers
Answer:
B. 16 degrees
Step-by-step explanation:
Because all of the angles in a triangle add up to 180 degrees, you can set up an equation for this problem:
2x - 10 + 4x + 46 + 3x = 180
Start by consolidating everything by adding like terms.
9x + 36 = 180
Then subtract 36 from both sides.
9x = 144
Then divide both sides by 9 to get your x.
x = 16

A team in science class placed a chalk mark on the side of a wheel and rolled the wheel in a straight line until the chalk mark returned to the

the wheel?
49.7 cm?
198.9 cm?
99.5 cm
19.6 cm?
Answers
Answer:
49.7 [tex]cm^{2}[/tex]
Step-by-step explanation:
Although it is hidden a bit, we are actually given the circumference of the circle, which is 25 cm.
We know that C = 2πr, so we can substitute variables to find the radius (r).
25 = 2πr
r = 25/(2π)
r = 3.9788... cm
The area of a circle is A = π[tex]r^{2}[/tex], so:
A = π [tex]3.9788^{2}[/tex]
A = 49.7359... [tex]cm^{2}[/tex]
A ≈ 49.7 [tex]cm^{2}[/tex]

the first term of a geometric series is 124. The sum to infinity is 64 . Find the common ratio
Answers
9514 1404 393
Answer:
-15/16
Step-by-step explanation:
The sum of a geometric series with first term a1 is ...
S = a1/(1 -r)
Then the common ratio (r) is ...
r = 1 -a1/S
For the given values, the ratio is ...
r = 1 - 124/64 = -15/16
The common ratio is -15/16.
Jacob went on a fishing trip. This year he caught 30 fish, which is six more than twice the number he caught last year. How many fish did Jacob catch last year?
Answers
Answer:
12 fish
Step-by-step explanation:
You need to work this problem backwards. If he caught 30 fish, which was six more than twice the number he caught last year, you would start by subtracting six, leaving you with 24. Then you'd have to divide by 2, because it was twice plus six as many fish, which would give you 12 fish.
[tex]\frac{30-6}{2}[/tex] = x
[tex]\frac{24}{2}[/tex] = x
12 = x
