Answer:

-48. You multiply the figures

Answer:

B. -48

Explanation:

Simply -16 multiplied by 3. When one negative number is multiplied, the product is a negative. When two negative numbers are multiplied together, the product is positive.

Answer:

It is 5 seconds     option C

Step-by-step explanation:

When the ball would hit the ground, h would reduce 0.

We can equate the R.H.S to 0.

∴ 0= -16t²+64t+80

0 = t² - 4t - 5              (dividing both sides by -16)

0 = t²+t - 5t -5  (by splitting the middle term)

0 = t ( t+1) -5 (t+1)

0= (t-5) * (t + 1)

when t-5=0   ;   when t+1=0

t =5           ;          t= -1                    time cannot be -ve

∴ t= 5 seconds

Hope this helps you.

Answer:

C)  5 seconds

Step-by-step explanation:

Given equation:

[tex]h=-16t^2+64t+80[/tex]

where:

The ball hits the ground when the height is zero.  

Therefore, substitute h = 0 into the given equation and solve for t.

[tex]\begin{aligned}\implies -16t^2+64t+80 & = 0\\-16(t^2-4t-5) & = 0\\t^2-4t-5 & = 0\\t^2-5t+t-5&=0\\t(t-5)+1(t-5)&=0\\(t+1)(t-5)&=0\\\end{aligned}[/tex]

Apply the zero-product property:

[tex]\implies t+1=0 \implies t=-1[/tex]

[tex]\implies t-5=0 \implies t=5[/tex]

As time cannot be negative, t = 5 only.  

Therefore, it takes 5 seconds for the ball to hit the ground.

The commission function is an illustration of the absolute functions

The commission for the sales of 7 cars is 16

The function is given as:

[tex]\mathbf{E(x)=\mid 5- \frac{6x}{2}\mid}[/tex]

When an employee sells 7 cars, we have:

x = 7

So, the equation becomes

[tex]\mathbf{E(x)=\mid 5- \frac{6\times 7}{2}\mid}[/tex]

Simplify

[tex]\mathbf{E(x)=\mid 5- 3\times 7\mid}[/tex]

[tex]\mathbf{E(x)=\mid 5- 21\mid}[/tex]

Simplify

[tex]\mathbf{E(x)=\mid- 16\mid}[/tex]

Remove absolute brackets

[tex]\mathbf{E(x) = 16}[/tex]

Hence, the commission for the sales of 7 cars is 16

Answer:

Question 1 : B) (8 x 20) - (8 x 1)

Question 2 :  D) (2 x 9) + (2 x 3)

Step-by-step explanation:

Distributive Property is used in algebraic expressions, to divide the equation, to make it easier to solve. For question 1,  since it was 20, you must subtract 8 from that answer, because 20 is 1 more than 19. For question 2, (2 x 9) + (2 x 3) would be the same thing as 2(9+3).

-kiniwih426

Answer:

B) (8 x 20) - (8 x 1)

D) (2 x 9) + (2 x 3)

Step-by-step explanation:

Distributive Property: "The distributive property tells us how to solve expressions in the form of a(b + c)."

___________________

Step 1: 8 x 19 = 152

Using PEMDAS, you can see which order to solve the equations in.

PEMDAS tells us to solve whatever is within the parenthesis first but there are 2 parenthesis and both have multiplication so just solve the first parenthesis first;

8 x 20 = 160

Step 2: We now have to solve the second parenthesis;

8 x 1 = 8

Step 3: Using PEMDAS, we see that after we solve the parenthesis, we do subtraction. So subtract 8 from 160.

160 - 8 = 152

So your answer is B) (8 x 20) - (8 x 1).

___________________

Step 1: 2(9 + 3)

Using the Distributive property, we multiply 2 by 9 and 3;

2 x 9 = 18

2 x 3 = 6

Now you are left with 18 + 6.

18 + 6 = 24

So your answer is D) (2 x 9) + (2 x 3).

Answer:

4m=12

4m/4 =12\4

m=3

Answer:

24

Step-by-step explanation:

Since the lines L and M are parallel:

Angle 1 and and 2 are alternate and their measurement is equal.

3x + 6 = 6x - 12 (we multiplied 6 with inside the parenthesis)

6 + 12 = 6x - 3x

18 = 3x divide both sides by 3

6 = x to find the angle measure replace x with 6

3x + 6 is 3*6 +  6 = 24

Assuming the expression is [tex]53.7 * 10^{4}[/tex].

Answer:

No

Scientific notation is where a number is written in the form [tex]a*10^{b}[/tex] where [tex]a[/tex] and [tex]b[/tex] are integers AND [tex]1<=a<10[/tex].

In our expression, [tex]53.7>=10[/tex], so it doesn't satisfy the requirements of scientific notation.

So, the answer is [tex]\boxed{no}[/tex], it's not written in scientific notation.

The equation of the line through the point (-4, 7) and with a slope of -5/2 is y = -5/2x - 3

The equation of a line in slope intercept form is expressed as:

[tex]y-y_0 = m(x-x_0)[/tex]

m is the slope

(x0, y0) is the point on the line.

Given the following parameters:

m = -5/2 and (x0, y0) =(-4, 7)

Substitute the given coordinates into the formula above;

y  - 7 = -5/2(x + 4)

2(y-7) = -5(x+4)

2y-14 = -5x - 20

2y = -5x - 20  + 14

2y = -5x - 6

y = -5/2x - 3

Hence the equation of the line through the point (-4, 7) and with a slope of -5/2 is y = -5/2x - 3
