Answer:

Roots = { 2, 5}

Vertex = (3.5, - 2.25)

Step-by-step explanation:

Roots

From the graph

x = {2, 5}

From factoring the equation

(x - 2)(x - 5) = 0

x = {2, 5}

--------------------------

The equation turns at the vertex

From the graph

(3.5, -2.25)

From the equation

X coordinate of vertex

x = -b/2a

x = 7/2 = 3.5

y = (3.5)² - 7(3.5) + 10

y = 12.25 -24.5 + 10

y = -2.25

Answer:

Option F, 10 inches.

Step-by-step explanation:

For a circle of radius R, the perimeter is:

P = 2*pi*R

such that pi = 3.14

If we have a section of that circle defined by an angle θ, the length of the arc is:

A = (θ/360°)*P =  (θ/360°)* 2*pi*R

In this case, we have a circle whose radius is defined by the length of the windshield wiper.

We also know that in one 90° revolution (so it travels the length of the arc of 90° two times) the tip travels a distance of 31 in.

Then:

A = 2*[(90°/360°)*2*3.14*R] = 31in

We need to solve this for R.

R = 31in/( 2*(90°/360°)*2*3.14) = 9.8in

We can round this to the next whole number:

R = 10in

The correct option is F.

Answer:

m = 2500b

Step-by-step explanation:

As instructed,

let b = number of boxes sold

let m = total money made.

The total money made, is a function of the number of boxes sold.

Let me break this down:

There are 100 pencils in a box;

if they sold only one box, they will get 100 X $25 = $2500;

if they sold two boxes, they will get 200 X $25 = $5000;

if they sold three boxes, they will get 300 X $25 = $7500;

Following the trend, we can deduce that money made, m = (number of boxes sold X 100 ) X $25

representing this using the variables we were given, we have

m = 100b X 25

hence

m = 2500b

Answer: 6.1

We are 95% confident that the true mean weight of the population is within 6.1 pounds of the sample mean 162.

At the 95% confidence interval, the margin of error for the mean is  6.1 pounds

The margin of error is "a statistic expressing the amount  of random sampling error in the results of a survey".

According to the question,

Number of random samples (n) = 132 residents

Mean of weight of random samples (x⁻)= 162

Standard deviation of random samples (σ)= 35 pounds

In order to find at the 95% confidence interval, the margin of error for the mean.

Margin error =  z (σ/√n)

The critical region 95% confidence interval under normal curve is 1.96.

= 1.96 (35/√132)

=1.96(35/11.48)

=1.96(3.0488)

= 5.9708636  ≈ 6.1 pounds

Hence, at the 95% confidence interval, the margin of error for the mean is  6.1 pounds.

Answer:

option c 6 is the correct ans

Answer:

1.  4   2. 2   3. Does not exist   4. Does not exist   5. 3

Step-by-step explanation:

1. This is the limit as x approaches 2 from the left.  That means that x "sneaks up" on 2, but from the left (ironically moving right). As  x  does that, the graph rises, heading for 4 (even though the point is "empty").  The limit is 4.  See attached image 1

2. Let  x  sneak up on 2 from the right (so moving left towards 2). As x does that, the graph falls, heading for the y-value 2.  The limit is 2.  See image 2.

3. This limit (two-sided) does not exist because the one-sided limits had different values.

4. This limit does not exist, either.  The limit as x approaches 0 from the left is 4.  The limit as x approaches 0 from the right is 0.  These are different, so the two-sided limit is not defined.

5. g(2) = 3, where the solid dot is.  It's the value of the function at x=2.

Answer:

3. The shape has two parallel sides(a,c and d,b in my picture). This is a parallelogram.

4. This shape has all the sides even and has 2 sides parallel to each other(d,b and a,c(picture)). This is a rhombus.
