Answer:
$40
Step-by-step explanation:
30 divided by 3 is 10 so 4 multiplied by 10 is $40
Replacing for values of a and c in the equation
a=20
c=8
m=4a+2c
m=4(20)+2(8)
m=80+16
m=96
Since
, and we know that
, we then also know that
.
Recall that
We take the positive root because we know that
. Then
Now,
Answer:
cosA = 40/41
tanA = 9/40
Step-by-step explanation:
Step 1: Find the other leg value
a² + b² = c²
9² + b² = 41²
b² = 41² - 9²
b = √1600
b = 40
Step 2: Draw out your triangle.
When you do so, you should see the cosA (adjacent over hypotenuse) is 40/41 and tanA (opposite over adjacent) is 9/40.
Triangle CBA
Length of AC = 40 (Leg)
Length of BC = 9 (Leg)
Length of AD = 41 (Hypotenuse)
cosA = AC/AB = 40/41
tanA = CB/AC = 9/40
Answer:
the answer is c. 3(a -2) -a +6b
Step-by-step explanation:
distribute
3a - 6 - a +6b
replace variables with the numbers (given)
3(5) - 6 -5 +6(1/3)
15 - 6 - 5 + 2
9-5+2
4+2
