On a black Friday, Jumia sold a pair of jeans trousers marked N7 000 at a discount of 10%. Find the Discount

Answer:

A

Step-by-step explanation:

We are given the two functions:

[tex]f(x)=4x+5\text{ and } g(x)=x^2-2x-2[/tex]

And we want to find:

[tex](f+g)(x)[/tex]

This is equivalent to:

[tex]=f(x)+g(x)[/tex]

Substitute:

[tex]=(4x+5)+(x^2-2x-2)[/tex]

Rearrange:

[tex]=(x^2)+(4x-2x)+(5-2)[/tex]

Combine like terms. Hence:

[tex](f+g)(x)=x^2+2x+3[/tex]

Our answer is A.

2. Substitution and Evaluate

[tex] \large{f(5) = - 4( {5})^{2} + 6(5) - 4}[/tex]

Remember to follow the PEMDAS/BODMAS rules! Exponent comes before multiplication.

[tex] \large{f(5) = - 4(25) + 30 - 4} \\ \large{f(5) = - 100 + 30 - 4} \\ \large{f(5) = - 74}[/tex]

Answer:-28

Step-by-step explanation:

Let A is the second number

the first number is 10.

The total is -18

=> 10 + A =-18 <=> A=-18-10=-28

Answer:

D. 9.7 in.

Step-by-step explanation:

the picture in the attached figure

we know that

area of the triangle is equal to

in this problem

A=47 in²

b=x

h=x

so

therefore

the answer is

x=9.7 in

Answer: $1.75

Steps: 30%=0.3

0.3 x 2.50 = 0.75

2.50 - 0.75 = 1.75

Answer: ≈ 5.2

Step-by-step explanation:

You're gonna want to use the Law of Cosines to solve:

c² = a² + b² -2abcos(R)

c² = 6² + 9² - 2(6)(9)cos(34°)

c² = 36 + 81 - 108cos(34°)

c² = 117 - 108(.82904)

c² = 27.46368

√c² = √27.46368  => 5.2405 = 5.2

Step-by-step explanation:

Circle A is located at (6, 5) and has a radius of 4 units. What is the equation of a line that is tangent to circle A from point C (2, 8)?

x = 2

y = −0.75x + 9.5

y = 1.33x + 1.66

x = 8

Answer:

(16, 6 )

Step-by-step explanation:

Basically you are expressing the points (dots ) in coordinate form

Locate x = 16 on the x- axis ( between 14 and 18 )

Then go vertically up to the point at (16, 6 )

Answer:

Step-by-step explanation:

What you wrote below the top line and the bottom line are not the same thing.

I think you really want the second line, but one can't be sure.

(1*2 + 5)/2 div (9/8)

7/2 // 9/8

7/2 * 8*9

7*8/18 = 56/18 = 28/9

If you really do want the top line (the latex) it is different.

1 2/5  div (8/9)     Is there such a thing as tfrac? I didn't know this but there is.

(1*5 + 2)5 // (8/9)

7/5 // 8/9             Invert the bottom fraction and multiply

7/5 * 9 / 8

63 / 40

1 23/40

Answer:

Use the referent of an adult stride (about 1 yard) to measure the dimensions of the area that will be covered by sod. Use the dimensions to calculate the area in square yards.

Step-by-step explanation:

This seems to be a relatively vague question, but it was requested so I'll try my best.

There's practically no way to accurately measure the area to be covered by sod without using a reference. I couldn't help but notice the list of references above the question, and I presume they are correlated. Since the length of an adult stride is 1 yard, you can use an adult stride as a reference to relatively accurately measure the dimensions of the area that needs to be covered. The method to find the area varies with the shape of the area, but assuming you can accurately find the area, this is a plausible way to estimate the area needed to be covered by sod. As an alternative, since the question stipulates sod can only be purchased in square yards or square meters, you can use a doorway (about 2 meters) in the list of references above the question to also measure the dimensions of the area. This is less practical because an adult stride is more mobile than a door.

Step-by-step explanation:

-17 = -2y + 13 - 8y

-17 = -10y + 13

-30 = -10y

3 = y

y = 3

Answer:

y = 3

Step-by-step explanation:

- 17 = - 2y + 13 - 8y

- 10y + 13 = - 17

- 10y + 13 - 13 = - 17 - 13

- 10y = - 30

- 10y ÷ - 10 = - 30 ÷ - 10

y = 3

Answer: 278.18

sorry if it's wrong

Step-by-step explanation: if you divide 255 by 11 you get 23.18181818181
