Hi!

There is no solution, because nobody defined f(x). There isn't enough information to solve the problem.

If it was f(x) = x + 26, the answer would be 16.

So the answer is no solution.

Find an explicit formula for the arithmetic sequence -11,-3,5,13,...

Answers

tn=-11+8(n-1). n represents which number of the sequence you will find, so if you plugged in a 3 you would find the third number in the sequence.

In this sequence, a1 = -11, k = 8

So an = a1 + (n-1)k = -11 + (n-1)*8 = 8n - 19

Answers

Because there is only one solution to this system, this means that the system is consistent and it is independent

consistent = system has at least one solution

independent = each equation isn't reliant on the other; i.e. one equation doesn't completely overlap the other

A number is multiplied by 2, and then the product is added to 9. The result is 49.

Answers

In order to solve this problem, use inverse operations. First subtract 9 from 49 to get 40, then divide 40 by 2 to get 20. So the original number it all started with was 20. You can check your work by following the instructions again. So 20*2=40, and 40+9=49.

Hope the explanation helped!

A number line contains points Q, R, S, and T. Point Q is on the coordinate 24, R is on the coordinate 28, S is on the coordinate 29, T is on the coordinate 42. Find the probability that a point chosen at random on QT is on ST. Express your answer as a percent.

25%
42.2%
50%
72.2%

Answers

This probability is going to be the length of segment ST divided by the length of QT so

P(ST)=(42-29)/(42-24)

P(ST)=13/18

As a percentage:

(p/100)=(13/18)

p=1300/18%

p=650/9%

p≈72.2% (to nearest tenth of a percent)

Answer:

The correct option is 4.

Step-by-step explanation:

It is given that Point Q is on the coordinate 24, R is on the coordinate 28, S is on the coordinate 29, T is on the coordinate 42.

Total numbers lie on line QT is

[tex]42-24=18[/tex]

The numbers lie on line ST is

[tex]42-29=13[/tex]

The probability that a point chosen at random on QT is on ST is

[tex]P=\frac{\text{The numbers lie on line ST}}{\text{Total numbers lie on line QT}}\times 100[/tex]

[tex]P=\frac{13}{18}}\times 100[/tex]

[tex]P=72.222\approx 72.2\%[/tex]

The probability that a point chosen at random on QT is on ST is 72.2%. Therefore option 4 is correct.

A window has the shape of a rectangle with a semi circle at the top. Find the approximate area of the window using the dimensions shown.

2ft by 4ft

Answers

First, let's find the area of the semi-circle.
Area of a circle = π*r²
Looking at the rectangle, the diameter for the circle is 2 ft. Since we need the radius though, divide the diameter by 2 to get the radius.
r = 1
A = π * 1²
A = π * 1
A = π

But since it's a semicircle, you need to divide that area by 2.
3.14/2 = 1.57

The area of the semi-circle is 1.57.

Area of a rectangle = lw
l = 2
w = 4
A = 2 * 4
A = 8

The area of the rectangle is 8.

Now add those together to get the area of the entire figure.

1.57 + 8 = 9.57

The figure is about 9.57 square feet.

The approximate area of the window is 9.57 ft²

The figure is a composite shape. Therefore, the area can be described as follows:

Area of the composite shape:area = area of semi circle + rectangle

area of a rectangle = lw = 4 × 2 = 8 ft²

area of the semi circle = 1 / 2 πr² = 1 / 2 × π × 1² = 1.57 ft²

Therefore,

area of the window = 8 + 1.57 = 9.57 ft²

The quadratic equation is 3(x + 5)^2 = 60

You solve it with these steps:

1) divide by 3:

(x + 5) ^2 = 60 /3

(x + 5)^2 = 20

2) extract square root

(x + 5) = +/- √20

3) subtract 5

x = - 5 +/- √20

Answer: 6 inches

Step-by-step explanation:

Given: The perimeter of the rectangle = 40 inches

Let the unknown side be w.

And the bottom side l=14 in.

We know that the perimeter of rectangle is given by :-

[tex]\text{Perimeter}=2(l+w)\\\Rightarrow40=2(14+w)\\\Rightarrow\frac{40}{2}=14+w\\\\Rightarrow20=14+w\\\Rightarrow\ w=20-14)\\\Rightarrow w=6\ in.[/tex]

Robert buys 3 pounds of bananas at $0.50 per pound and 3 pounds of apples at $1.00 per pound. Which of the following expressions represents the total cost of the fruit he bought (in dollars

Answers

Well I mean we know he spent a total of $4.50, but since we don't have any of the answer choices this is almost impossible.

Answer:

The answer is $3(0.50+1.00)

Step-by-step explanation:

Robert bought 3 pounds of bananas at $0.50 per pound which can be expressed as:

[tex]3*0.50[/tex]

And 3 pounds of apples at $1.00 per pound which can be expressed as:

[tex]3*1.00[/tex]

As Robert bought the apples and bananas, you can add both expressions:

[tex]3*0.50 + 3*1.00[/tex]

This expression can be factorized as:

[tex]3(0.50+1.00)[/tex]

[tex]3(1.50)[/tex]

Both expressions will give you the same result, which is $4.50.

"Our proportionality constant would be how much the rope stretches versus the weight being hung. This is set up by simply dividing the two numbers.

9.6 inches / 8 pounds

or for every pound hung, it will stretch 1.2 inches so we know if it stretches 6 inches, we can set up an equation 6 inches = 1.2 [inches/pound] * pounds solve for weight to get 5 pounds being hung from the rope."
