4 0

Answer:

A=x^2+12x+27\ units^2

Step-by-step explanation:

we know that

The area of the model is equal to the area of a rectangle

The area of a rectangle is equal to

A=LW

we have

L=x+9\ units

W=x+3\ units

substitute

A=(x+9)(x+3)

Apply distributive property

A=x^2+3x+9x+27

Combine like terms

A=x^2+12x+27\ units^2

10. The probability of buying pizza for dinner is 34% and the probability of buying
kipiarov [429]

Answer:

The probability of eating pizza given that a new car is bought is 0.952

Step-by-step explanation:

This kind of problem can be solved using Baye’s theorem of conditional probability.

Let A be the event of eating pizza( same as buying pizza)

while B is the event of buying a new car

P(A) = 34% = 0.34

P(B) = 15% = 15/100 = 0.15

P(B|A) = 42% = 0.42

P(B|A) = P(BnA)/P(A)

0.42 = P(BnA)/0.34

P(B n A) = 0.34 * 0.42 = 0.1428

Now, we want to calculate P(A|B)

Mathematically;

P(A|B = P(A n B)/P(B)

Kindly know that P(A n B) = P(B n A) = 0.1428

So P(A|B) = 0.1428/0.15

P(A|B) = 0.952

Given the picture below, find x and both angles.
Lisa [10]

Answer:

x =42.5

x+8 =50.5

3x+2 =  129.5

Step-by-step explanation:

The two angles shown are supplementary, so they add to 180

x+8   + 3x+2 = 180

Combine like terms

4x+10 = 180

Subtract 10

4x = 170

Divide by 4

x =42.5

x+8 = 42.5+8 = 50.5

3x+2 = 3*42.5 +2 = 127.5 +2 = 129.5

What are the period and phase shift for f(x) = 3 tan(4x + π)?
Pie
For an equation y = a tan[b(x+c)], the period is equal to 2*pi/b, while the phase shift is c.
This equation can be rewritten as:
f(x) = 3 tan [4(x + pi/4)]
In this case, b = 4, c = pi/4
Then the period = 2*pi/b = pi/2.
The phase shift = pi/4 (to the left).

sineoko [7]

Answer:

5

Step-by-step explanation:

Apply Pythagorean theorem

13 {}^{2}  = 12 {}^{2}  + x {}^{2}  \\ 169 = 144 + x {}^{2}  \\ x {}^{2}  = 169 - 144 \\ x {}^{2}  = 25 \\ x =  \sqrt{25}  \\ x = 5
