Answer:
t = 3 seconds
Step-by-step explanation:
Here h(t) = -16t^2 + 144.
When the quarter hits the ground, its height will be 0 feet. Letting h(t) = 0 results in -16t^2 + 144 = 0, or 16t^2 = 144, or
144
t^2 = ------------ = 36/4 = 9 seconds^2
16
Therefore, the time, t, required for the quarter to hit the ground is t = √9, or t = 3 seconds
Answer:
.50 cents
Step-by-step explanation:
8.15 divided by 16 equals .50
The coefficient of the term 13a is 13
The coefficient of 6b in expression is a + 6b is 6
<em><u>Solution:</u></em>
<em><u>Given expression is:</u></em>
13a + 6b
We have to find the coefficient of 13a
The coefficients are the numbers that multiply the variables or letters
Here in 13a , a is the variable that is multiplied with number 13
Thus the coefficient of the term 13a is 13
<em><u>Second expression:</u></em>
a + 6b
Here, in 6b , b is the variable that is multiplied with number 6
so 6 is the coefficient
Assuming simplify then
get rid of parenthasees by assuming that there is a 1 in front of each, so multply by 1 and get rid of partenthasees so
5p^2-3+2p^2-3p^3
add like terms
7p^2-3p^3-3
normally ordered with biggest exponenst to the left from left to right decending
so
-3p^3+7p^2-3
Answer:
$70
Step-by-step explanation:
Daria's total income = fixed income + variable income
Let
Daria's Fixed income = x
additional $30 if the buyer gets an extended warranty
Daria's variable income = 30s
Where,
s = number of televisions with extended warranties she sells
If Daria sells 15 televisions with extended warranties, she earns \$1,500. Find her fixed income
Daria's total income = fixed income + variable income
1500 = x + 30(15)
1500 = x + 450
1500 - 450 = x
1,050 = x
x = $1,050
Daria's total fixed income = $1,050
How much is the fixed amount Daria for each television?
Fixed income per television = Total fixed income / number of television sold
= 1050 / 15
= 70
Fixed income per television = $70
