Can you help me with question 4 step by step

Answer:

1

answer is D

Step-by-step explanation:

we must calculate it from this equation :

x³ -9x²+27x-25 then

[tex] {2}^{3} -( 9 \times 4 )+ (27 \times 2) - 25 = 1[/tex]

Answer:

No

Step-by-step explanation:

3rd option should be changed to "will not".

9514 1404 393

Answer:

Step-by-step explanation:

Whether the offered numbers will satisfy the inequality is more easily seen by solving it for x.

  6 + 3x ≤ 15

  3x ≤ 9 . . . . . . . . . subtract 6 from both sides

  x ≤ 3 . . . . . . . . . . divide by 3

This is "x is less than or equal to three."

  2 is less than 3 so will meet Mari's goal

  3 is equal to 3, so will meet Mari's goal

  4 is not less than or equal to 3, so will not meet Mari's goal

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:

Step-by-step explanation:

tan is the same thing as sin/cos. therefore,

[tex]tan(-\frac{\pi}{2})=\frac{sin(-\frac{\pi}{2}) }{cos(-\frac{\pi}{2}) }[/tex]

[tex]sin(-\frac{\pi}{2})=-1[/tex] and [tex]cos(-\frac{\pi}{2})=0[/tex] so

[tex]tan(-\frac{\pi}{2})=-\frac{1}{0}[/tex] which is undefined. On the graph, this is represented by an asymptote. So your answer is true.

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 )

Hello! answer: 9

Step-by-step explanation:

Formula for triangle area: base × height ÷ 2 or base × height × 1/2

6 × 3 = 18 18 ÷ 2 = 9 therefore 9 is the area!

Answer:

the answer is the last one, f(x) = 4x + 3

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.

Answer:

[tex]\sqrt[3]{x^2}[/tex]

Step-by-step explanation:

x ^ (5/6)   / x ^ (1/6)

We know that a ^b  / a^ c = a^ (b-c)

x^ ( 5/6 - 1/6)

x^ (4/6)

x^ ( 2/3)

[tex]\sqrt[3]{x^2}[/tex]

Answer:

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

Can someone plz help me

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:-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: ≈ 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

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:

1.6/x=3/8

do cross multiplication

x*3=6*8

x=48/3

x=16

2.b/8=3/4

do cross multiplication

b*4=8*3

b=24/4

b=6

4.n/8=35/7

do cross multiplication

35*8=7*n

280=7n

280/7=n

1. How to find f(5)?

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]
