Answer:
3 and 7
Step-by-step explanation:
You know from your multiplication tables that ...
21 = 1×21 = 3×7
There are no other factorizations of 21 using integers. You may notice that the sums of these factors are ...
1+21 = 22
3+7 = 10 . . . . . . this is the pair of numbers you are looking for
The two numbers are 3 and 7.
Answer:
a = -2
b = 3
c = 2
Step-by-step explanation:
Put the equation in standard form:
f(x) = -2x² + 3x + 2
Now you can pull out the numbers for each variable.
Answer:
Step-by-step explanation:
Formula
Area = 1/2 (b1 + b2)*h
Givens
b1 = 11 m
b2 = 13 m
Area = 96
h = ?
Solution
96 = 1/2 (11 + 13) * h Multiply by 2 Combine the bases as well.
96*2 = (24) * h Divide by 24
96*2/24 = h Multiply by 2 and divide by 24
h = 8
Answer:
A) car one is linear because it decreases the same amount every year.
car two decreases by the same ratio so it's exponential.
B) for car one y = -6,000x + 38,000 (y is the value after x years, -6,000 is what it changes by every year, and 38,000 is the amount of year 0)
for car two y = (44,000) (17/20)x-1 (y is the value after x years, 44,000 is the amount on year 0, and 17/20 is the ratio)
C) after 5 years car one will be 8,000
after 5 years car two will be about 16,860
Sample space = HHH, HHT, HTH, THH, TTT, TTH, THT, HTT (8 possibilities)
Desirable outcomes = TTH, THT, TTH (3 possibilities)
Required probability = 3/8
