Answer:
x= -5 and x= 3
Step-by-step explanation:
You have the factored equation, all you need is to switch the signs on the numbers and that is the answer.
Answer:
c) 0.6827
Step-by-step explanation:
We have to find P(-1<Z<1) by using z-table
P(-1<Z<1) = P(Z<1) – P(Z<-1)
P(-1<Z<1) = 0.841345 - 0.158655
P(-1<Z<1) = 0.682689
P(-1<Z<1) = 0.6827
Answer:
So first, there is an acronym for the strategy, KFC.
°π°
Keep the first fraction. Ex, 4/5 ÷ 1/5
Flip the second fraction. Ex, 4/5 ÷ 5/1
Change symbol. Ex, 4/5 ÷ 5/1 turns into 4/5<em>x</em>5/1
Answer:
a. He started with $50 in the the account.
b. The account grow by $10 dollars each week
c see graph
Step-by-step explanation:
y = 50 + 10x
We can rewrite this as
y = 10x+50
This is in the form y = mx+b
where m = 10 which is the slope and b =50 which is the y intercept
The y intercept = 50 is the starting value or the value when x = 0
a. He started with $50 in the the account.
The slope is how much it grows by as x grows. As x increase by 1 , y will grow by the slope or 10, so the account will grow by 10 each week.
b. The account grow by $10 dollars each week
c see graph
Given the ratio, you know that:
length = 6x
width = 2x
height = 7x
Because the sum of the length and the width is 24 cm, you can write the equation:
6x + 2x = 24
Solve:
8x = 24
x = 3
Plug the 3 back into the expressions written earlier for length, width, and height.
length = 18 cm
width = 6 cm
height = 21 cm
Use the formula SA = 2B + Ph to solve for the surface area.
Surface Area = 2(area of the base) + (perimeter of the base)(height)
I'm going to plug in l, w, and h as variables for length, width, and height to show the exact way to solve for the B and P.
SA = 2lw + 2(l + w)h
SA = 2(18)(6) + 2(18 + 6)(21)
SA = 216 + 2(24)(21)
SA = 216 + 1008
SA = 1224
The surface area is 1,224 cm^2.
