Answer:

3600

Step-by-step explanation:

Since the question gives you p, you replace p (which is just a placeholder) with 5.

Your equation should look like this:

[tex](6*2(5))^2 = 3600[/tex]

Answer:

Step-by-step explanation:

-364 - 104 i

Answer:

The scientific notation will be Letter D

Answer:

Step-by-step explanation:

Corresponding angles are equal

Answer:

I will provide the steps below.

Step-by-step explanation:

First, You will need to plug in the 8.

2(8)-(1/-3)=-5  

Multiply

16-(-1/3)=-5

If we have two negitive it turns into possitive.

16+1/3=-5

16+1/3=-5

This statement is not true becuase if y=8 the equation will be (16+1/3)=5

*Make sure your giving me the right eqution otherwise this statment is false.*

Answer:

G

Step-by-step explanation:

you just see the place value of the number you are multiplying by and you you put the place value. For example ( 3× 0.01)   is going to be ( 0.03) if it makes it easier just take the 3 and substitute it for the 1.

Answer:

C

Step-by-step explanation:

In the graph it's curved, which is not linear, but the other lines are all straight.

Answer:

h = -8/5

Step-by-step explanation:

21 = -4h +13-h

simplify the right side

21 = -5h + 13

subtract 13

21 = -5h + 13

-13          - 13

8 = -5h

divide by -5

8 = -5h

/-5  /-5

[tex]-\frac{8}{5} = h[/tex]

Answer:

25.2

Step-by-step explanation:

14litres : 70 km

     ?     : 126km

126/70 = 1.8

14 x 1.8 = 25.2

25.2 litres of petrol

please mark as brainliest.  thank you

Answer:

25.2 litres

Step-by-step explanation:

using proportion

let the amount of petrol we are searching for be x

14litres/xlitres =70km/126km

cross multiply

70x=126×14

70x =1764

x=1764/70

x=25.2litres

Answer:

6 and -8

Step-by-step explanation:

Solve:

xy = 48

x + y = -2

You can say y = -2-x = -(x+2) and then substitute that in the first:

-x(x+2) = 48

-x² -2x - 48 = 0

x² + 2x + 48 = 0

Quadratic formula can do the rest if you don't "see" the factorization.

Answer:

X = 3   Y = -3

Step-by-step explanation:

The arrow is on X = 3 and the other side of arrow is on Y = -3

Answer:

b) 458.9

Step-by-step explanation:

the tenths digit is the 8 right of the decimal so if you were to round, it would be 458.9 because 7 is closer to 10 than zero.

Answer:

thats hard

Step-by-step explanation:

Answer:

-y² - 4y - 6

Step-by-step explanation:

Step 1: Write expression

5y² - 6y - 11 - 6y² + 2y + 5

Step 2: Combine like terms (y²)

-y² - 6y - 11 + 2y + 5

Step 3: Combine like terms (y)

-y² - 4y - 11 + 5

Step 4: Combine like terms (constants)

-y² - 4y - 6

Answer:

x=9.4

b=77.2

Step-by-step explanation:

a+b=180

as they are interior angles

(6x-48)+(4x+38)=180

6x-48+4x+38=180

6x+4x+38-48=180

10x+86=180

10x=180-86

10x=94

x=94/10

x=9.4

b=(4x+38)

b=4x+38

b=4(9.8)+38

b=39.2+38

b=77.2

Answer:

So we reject the null hypothesis and accept the alternate hypothesis that rats learn slower with sound.

Step-by-step explanation:

In this data we have

Mean= u = 18

X= 38

Standard deviation = s= 6

1) We formulate the null and alternate hypothesis as

H0:  u = 18  against           Ha : u > 18  One tailed test .

2) The significance level alpha = ∝= 0.05 and  Z alpha has a value ± 1.645 for one tailed test.

3)The test statistics used is

Z= X- u / s

z= 38-18/6= 3.333

4) The calculated value of z = 3.33 is greater than the z∝ = 1.645

5) So we reject the null hypothesis and accept the alternate hypothesis that rats learn slower with sound.

First we set the criteria for determining the true of value of the variable. That whether the rats learn in less or more than 18 trials.

Then we find the value of z for the given significance value given and the test about to be checked.

Then the test statistic is determined and calculated.

Then both value of z and z alpha re compared. If the test statistics falls in the rejection region  reject the null hypothesis and conclude alternate hypothesis is true.

The figure shows that the calulated z value lies outside the given z values

Could I please have BRAINLIEST.

[tex]f(x) = -5x + 2[/tex]          [tex]g(x) = \frac{1}{2}x - 4[/tex]

[tex]f(g(x)) = -5(\frac{1}{2}x - 4) + 2\\= -\frac{5}{2}x + 20 + 2\\= -\frac{5}{2}x + 22[/tex]

f(x)=-5x+2     g(x)=1/2x-4

find f(g(12))

-5(1/2x - 4) + 2

-2.5x + 20 + 2

-2.5 + 22

Hope this helps! :)

Answer:

f(5) = 5

Answer:

16

Step-by-step explanation:

First, we solve for x.

[tex]2x+7=-21\\2x=-28\\x=-14[/tex]

We now evaluate 2-x, plugging in -14 for x.

[tex]2-x\\2-(-14)\\2+14\\16[/tex]

12.5

2x+7=-21

2x+7-7=-21-7

2x=-28

2x/2=-28/2

x=-14

2-x=?

2-(-14)

2+14=16
