Exponential Growth
Step-by-step explanation:
The function is increasing and not decreasing. Because the base is greater than 1, the equation represents exponential growth. If the base were to be less than 1, then it would represent exponential decay.

Find the measure of FG.
Can someone help??
Answer:
28
Step-by-step explanation:
Side FG = Side DG. Therefore, 5x - 17 = 3x + 1, or 2x = 18, or x = 9.
If x = 0 then the length of side FG is 5(9) = 17, or 28.

(sat prep) find the value of x
Answer:
140 degrees
Step-by-step explanation:
Im only a freshman, but i think i got it, i just assumed that the other small part at the bottom was also 20 degrees, which would mean that you are missing the 140 degrees from the 180 degree line
Answer:
120 degrees
Step-by-step explanation:
The bottom part is 40 degrees,
the two lines are parallel, so theoretically, you can just put them together. Then using vertical angles, you can tell it's 40 degrees.
40 + 20 = 60
180-60 degrees is 120 degrees.

Richmond High School has 1900 students and is shrinking by 15 students per year. Write a rule that represents the population at Richmond High School. Let x represent years and y represent population.
Answer:
y = -15x + 1900
Step-by-step explanation:
This is correct because, your base number is 1500, so that is your y-intercept. The school's population is shrinking by 15 students per year so, that becomes your slope. Hope I helped. ;)

For a circle of radius 4 feet, find the arc lengeth, S subtened by a central angle of 26 degrees
Answer:
Exact answer = 26π/45 feet.
or we can write it as 1.815 feet to the nearest thousandth.
Step-by-step explanation:
The circumference of the circle = 2*4*π = 8π feet.
So the length of S = (26/360) * 8π
= 26π/45 feet.
Splitting investments. Joan had $3,000 to invest. She invested part of it in an investment paying 8% and the remainder in an investment paying 10%. If the total income on three investments was $290, than how much did she invest at each rate?
Answer:
Step-by-step explanation:
From the given information:
Let assume that the invested amount in the investment paying 8% interest is a
Now, since the total amount invested = $3000.
Then, the amount invested in the investment that will be paying 10% interest can be represented as:
= $(3000-a)
Income earned on $a that is being invested in 8% interest = $a × 8/100 = $0.08a
Income earned from $(3000-a) in the 10% investment is:
= $(3000-a)× 10/100
= $(300 - 0.1a)
Since total income of the two investment = $290;
Then;
0.08a + (300 - 0.1a) = 290
0.08a + 300 - 0.1a = 20-
300 - 0.02a = 290
-0.02a = -10
a = -10/-0.02
x = 500
Thus;
the amount invested in an investment paying 8% interest = $500
the amount invested in an investment paying 10% interest = $(3000 - 500) = $2500

A water tank contains 320 litres of water, correct to the nearest 10 litres. 50 litres of water, correct to the nearest litre, are removed from the tank. Calculate the upper bound of the amount of water left in the tank.
Answer:
[tex]N_l=270 litres[/tex]
Step-by-step explanation:
From the question we are told
Total litres of water [tex]N_t=320[/tex]
Total litres removed [tex]N_r=50[/tex]
Generally the Total litres left in the tank N_l is mathematically given as
[tex]N_l=N_t-N_r[/tex]
[tex]N_l=320-50[/tex]
[tex]N_l=270 litres[/tex]
Therefore the total water left in the tank is
[tex]N_l=270 litres[/tex]
Why is x = 6 a solution to the proportion 192/36 = 32/x ?
Because if 192/36 = 5.3333 and 32/6 = 5.3333 then the solution is right
Answer:
It is a solution because when you divide 192 by 36 you get 5 and one third. When you divide 32 by 6 you also get 5 and one third. This means they are equal.
Step-by-step explanation:
A ball is thrown into the air from a height of 4 feet at time t=0. The function that models this situation is h(t)=-16t^2+63t+4. What will be the height of the ball after 2 seconds?
Answer:
66 feet
Step-by-step explanation:
We know that the t in the equation represents the time. So, substitute 2 for the t in the function and simplify to find the height after 2 seconds:
[tex]h(t) = -16t^2+63t+4\\h(2) = -16(2)^2+63(2)+4\\h(2) = -16(4)+126+4\\h(2) = -64 + 126+4\\h(2) = 66[/tex]
Thus, the height would be 66 feet.
5 g of margarine contains 3.6 g
of fat.
How many grams of fat are
there in 82 g of margarine?
Answer:
59.04g of fat
Step-by-step explanation:
I) Figure out how much grams of fat is in 1g of margarine:
3.6 ÷ 5 = 0.72
II) Next, we can figure out how much fat is in 82 g of margarine:
0.72 × 82 = 59.04
One shot formula:
(3.6g ÷ 5g) × 82g = 59.04g
