Your neighbor leaves his yard, which is 120 ft from the bus stop. He begins to walk toward you at the bus stop and then passes you. He walks at
a speed of 4 ft/s. His distance d from you after t seconds is given by d = 120 - 4t). After how many seconds is your neighbor 30 ft from you?
A.-22.5 s and -37.5 s
B. 22.5 s and 37.5 s
C. 30 s
D. 15 s and 45 s

Answers

Answer 1

Answer:

ANSWER B

Step-by-step explanation:

d=(120-4t)

30=120-4t

4t=120-30=90

t=90/4=22.5 s

-30==120-4t

4t=120+30=150

t=150/4=37.5 s

¿Cuánto es P(4 o factor de 90)?
Escribe tu respuesta como una fracción o como un número entero.

Answers

Answer:

P (4 or factor of 90) = 1

Step-by-step explanation:

Given :-

Three cards numbered 2, 3, 4

To Find :-

P (4 or factor of 90)

Solving :-

4 is required and we know that 2 and 3 are both factors of 90.

Therefore, P (4 or factor of 90) = 1

Solution :-

P (4 or factor of 90) = 1

Answer:

1

Step-by-step explanation:

P(2) = 1/3

P(3) = 1/3

P(4) = 1/3

2 and 3 are factors of 90

⇒ P(factor of 90) = P(2) or P(3) = 1/3 + 1/3 = 2/3

Therefore,

P(4 or factor of 90) = P(4) or P(factor of 90) = 1/3 + 2/3 = 1

(9x + 4) (2x2 – 17x - 9) = 0
-

Answers

Step-by-step explanation:

So leave (9x+4) and factor (2x2-17x-9) .

Factors into (2x+1)(x-9).

Now set (9x+4)=0 and find x. x= -4/9

set (2x+1)=0 x = -1/2

set x-9=0 so x=9. you have 3 solutions which are -4/9, -1/2, and 9.

Answers

Answer: Y= 2/3x + 9

Explanation: The equation is in slope-intercept form, y=mx+b. Since it is parallel to the equation, it has the same slope (2/3x) and since b is the x intercept, b is 9.

The equation in slope-intercept form for the line that is parallel to y=(2/3)x-10 and x-intercept at 9 is y =

What is a Linear Equation of a line?

A linear equation is an algebraic equation of the form y=m x + b. involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept

Parallel lines have the same slope.

Given data ,

The x-intercept is obtained when we set the value y = 0

As the x-intercept is 9 , therefore the point representing the x-intercept will be: ( 9 , 0 )

Now , the equation of line is given by y = m x + c

And , y = ( 2 / 3 ) x - 10

Since the lines are parallel , they will have same slope

So , the equation in slope intercept for the line will be

y = ( 2 / 3 ) x + 9

Hence the equation of line will be y = ( 2 / 3 ) x + 9

  d)  m∠a = m∠f

Step-by-step explanation:

Where a transversal crosses parallel lines, certain relationships between the angles are established. Effectively, the two same-side interior angles are supplementary, as they would be in a parallelogram. Here, those are angles B and F, or angles A and E.

The vertical- and linear-angle relationships give rise to all of the other ways this is expressed. For example, angles A and B are a linear pair, so supplementary. Since B and F are supplementary, and B and A are supplementary, F = A. Using more formal language, ...

What is compound interest?

Compound interest is when both the amount deposited and the interest already accrued increase in value when interest is paid.

The formula that can be used to determine value of the account is:

B=p(1+r)^t

Write the polynomial in factored form. Show all the steps that you use to solve this problem.

x^3 - 3x^2 - 10x

Answers

Answer:

x( x - 5)( x + 2)

Step-by-step explanation:

The polynomial is x^3 - 3x^2 -10x. Since each term has at least one x, we can factor out an x.

This gives us x( x^2 - 3x - 10).

Now, we may factor the second degree polynomial.

_ × _ = -10? (or a × c, where ax^2 + bx + c?)

_ + _ = -3? (or b?)

Well, -5 times 2 equals 10, and -5 plus 2 equals -3.

We use these values to factor further.

So, our final answer becomes x( x - 5 )( x + 2 ).

You can check this by simply multiplying and distributing the terms!

Answers

Answer:  161 m^2

Step-by-step explanation:

The surface area composes of 4 triangles and 1 square.

The side length of the square is 7 m, so the area is 49 m^2 because the area of a square is the side length^2.

Each of the triangles has a base of length 7 m and a height of 8 m, so the area of each triangle is 7m*8m/2 = 28 m^2 because the area of a triangle is the base*height/2.

Since there are 4 triangles, the total surface area of the 4 triangles is 28 m^2 * 4 = 112 m^2.

Adding that to the area of the square, we get 49 m^2 + 112 m^2 = 161 m^2
