Answer:

The toy reaches the ground in 10 sec

Step-by-step explanation:

When the rocket hits the ground, h becomes zero (0).  Thus, our problem here is to solve the equation h(t) = −4.9t^2 + 50t + 2 = 0,

Because of the fractional coefficient -4.9, it's best to use the quadratic equation here.  The coefficients of the t terms are {-4.9, 50, 2}.  Thus,

the discriminant is b^2 - 4ac  = 50² - 4(-4.9)(2) = 2539.2, and the square root of this is 50.39.

The quadratic formula is as follows:

      -b ± √discriminant

t = -------------------------------

                 2a

which here is:

      -50 ± 50.39

t = ------------------------      Since t represents time, only the positive result

               -9.8                 is relevant here; it is 10.24 sec,

which rounds off to 10 sec

Step-by-step explanation:

The sample mean is equal to 24 and population mean is equal to 25

Sample mean represents the measure of the center of the data. The sample mean formula is used to calculate the average value of the given sample data.

Sample mean= sum of the terms/number of the terms

What is population?

The population in static is used for a collection of data. The population mean can be calculated by the sum of all values in the given population divided by a total number of values in the given population.

Population mean= sum of the population/ number of the population

From the given question average of entire year is 25.

According to the population mean formula the sum of the population by number of the population is nothing but the average of the entire year. Thus the population mean is 25.

According to the sample mean formula,

sample mean= sum of the terms / number of the terms

⇒(25+10+16+39+27+25+32+25+25+22+28+14)/12 = 24

Thus the sample mean is equal to 24 and population mean is equal to 25

Answer:

C. y = 1/2x + 5

Step-by-step explanation:

For A. and B. x to a power of something, if x is at a power of anything, like x^2 or x^3, then it is not linear.

For D. it doesn't even have x in it, so basically y equals a number.

C. is a linear equation, y = 1/2x + 5

Answer:

angle 2

Step-by-step explanation:

complementary angle to angle 1 is angle 2 because in complementary angle sum of two amgle is 90 degree and when we add angle 1 and angle 2 it gives us 90 degree since they are perpendicular.

2. If eight kids get to go to the water park for $60. Do the same as i did on the first one. Just multiply them.

$60 = eight kids

So every kids has to pay $7.5 to go to water park.

Answer:

Company B, since 40 > 25 and 40 > 35

Step-by-step explanation:

Company A:

With each window more, price increases by 25

Company B:

15, 55, 95, 135, 175

With each window, the price increases by 40

Company C:

y = 35x + 25

x = number of windows

If x increases by 1, the price increases by 35, therefore, this is the increase per window

Add the unit label

Answer:

A

Step-by-step explanation:

V = (0.04)*H (Company P)

V = (0.06)*H (Company S)

V represents the vacation hours and H is the hours worked

If they both work 2080 hours

V1 = (0.04)*(2080) = 83.2 vacation hours (Company P)

V2 = (0.06)*(2080) = 124.8 vacation hours (Company S)

124.8 - 83.2 = 41.6 hrs

Answer:

1 hour 10 minutes.

Answer:

3. Since it asked us to write question 3 in the from y=mx + c

m is the gradient

c is the intercept on y axis or where the line enters or cuts the y axis. This can be seen from the diagram. The line cuts the y axis at "9". (Check the diagram for this).

Now to find m.

Pick points on the line

Say (1,6) and (2,3)

Gradient = m = y2 - y1/(X2 - X1)

x1 = 1

y1 =6

x2 = 2

y2 = 3

Substituting into that formula

m = 3 - 6/2 - 1

m= -3/1

m= -3.

Since we've gotten what we need

y=mx + c

Y= -3x + 9.

4. 4x + 2y = 12

Rearranging by making y subject to suit the eqn...y=mx + c

you have

m is the gradient and c is the intercept.

2y = -4x + 12

Divide through by 2

y= -2x + 6

y=mx + c

By comparing...

m==gradient = -2

c== Intercept = 6

5). Doing the same thing we did above

-6x + 3y =21

Making y subject

3y = 6x + 21

Divide through by 3

y= 2x + 7

y=mx + c

m==gradient =2

c==Intercept =7.

Hope this helps.

Have a great day!
