Answer:
.70(x)+1.15(25)=48
Step-by-step explanation:
Answer:
3-3 -4-3=0
Step-by-step explanation:
just divide 3-3 and -4-1 and u get your answer
First problem:
cos (theta)=1
Using the inverse cosine function, you get theta = 0.
Now we find tan 0 = 0
cot(theta) = 1/tan(theta) = 1/0
Division by zero is undefined, so the answer is d. undefined
Second problem:
cos (theta)=1
Use the inverse cosine function.
theta = 0°
Answer: c. 0°
Write the word problem in algebraic form:
n2 -14 = 5n
Write as a quadratic:
n2 - 5n - 14 = 0
Factor:
(n+2)(n-7) = 0
Solve:
n+2 = 0 => n = -2
n-7 = 0 => n = 7
positive solution is 7. (14 less than 72 = 35 which is also 5 times 7)
Answer:
a = 72
Step-by-step explanation:
Subtract 56 from both sides of the equation so you can isolate the variable
128-56=72
