Answer:
3.37= true 3.38=false
Step-by-step explanation:
3.37. fill in the blanks
then multiply them together
and you get your answer
3.38. fill in the blanks
then find the exponent of 2
then times that by 3
And you get your answer
3.40. write down your order of operations PEMDAS
so first you do the parentheses (7+3)=10
then you see if there is any exponents
there is so you do that next (10^2)=100
then you see if there is any multiplication
there is so you do 2×100= 200
there now you got you answer
Answer:
Step-by-step explanation:
y = 3x² + 9x
= 3(x² + 3x)
= 3(x² + 3x + 1.5²) -3·1.5²
= 3(x+1.5)² - 6.75
vertex (-1.5, -6.75)
Answer:
This spyware is detected 66% of the time.
Step-by-step explanation:
We have these following percentages:
70% of the time, the spyware arrives via the internet, and in this case, is detected 60% of the time.
30% of the time, the spyware arrives via e-mail, and in this case, is detected 80% of the time.
What percentage of times is this spyware detected
Sum of 60% of 70%(arrived via spyware, detecte) and 80% of 30%(arrive via e-mail, detected). So
This spyware is detected 66% of the time.
A^2 + b^2 = c^2
7^2 + 4^2 = 65
square root of 65 is 8.06
answer: 8.06
5(-2)(4)^2 + 2(4) + 7(-2)
5(-2)(16) + 2(4) + 7(-2)
-160 + 2(4) + 7(-2)
-160 + 8 + 7(-2)
-160 + 8 + -14
-160 + 8 - 14
-166
The answer is: -166.
