Step-by-step explanation:

The time which it will take for the ball to hit the ground after bring thrown from a height of 40 meters as described in the task content is; 2.37 seconds.

It follows from the task content that the equation given for the height, h in meters of the ball thrown is;

h = 40 - 5t - 5t²

Therefore, when the ball hits the ground, the height at this point is; 0.

0 = 40 - 5t - 5t²

Divide through by -5 so that we have;

t² + t - 40 = 0.

Hence, by solving using the quadratic formula; the values of t are;

t = 2.37 sec or -3.37 sec.

Ultimately, since the time taken can only have a positive value, it follows that the time taken by the ball to hit the from the 40 meters height is; t = 2.37.

Answer:

2+2x(7/7)= 0 (you do what's in the parenthesis first)

2+ 2x (1) =0 (then you multiply, and anything times 1 is itself)

2 + 2x= 0 (subtract 2 from both sides to get the x-term alone)

2x= -2 (divide both sides by 2 to get x isolated)

x= -1 (is your answer)

Answer:

94 degrees

Step-by-step explanation:

triangle is 180

so 180-74-20=86

The exterior angle is 74+20=94

94 is exterior angle

Answer:

x = 94°

Step-by-step explanation:

Any triangle has three angles whose measures add up to a total of 180°.

This triangle has two known angle measures. First, find the missing interior angle measure.

180 - (74 + 20)

180 - 94

86

The missing interior angle's measure is 86°. An exterior angle is supplementary to its adjacent interior angle, which means that the measure of the interior angle plus the exterior angle measure is 180.

180 - 86

94

Another way to find out a missing exterior angle measure is to simply add the measures of the two nonadjacent interior angles.

74 + 20

94

Explanation:

Check out the diagram below

I drew a rectangle with dimensions 56 ft by 78 ft.

Then I broke up the 56 into 50+6, and I broke up the 78 into 70+8

The reason for this is because it's fairly easy to multiply the areas of each smaller rectangle at this point

Add up all the areas found: 3500+420+400+48 = 4368

As a way to check, using your calculator shows that 56*78 = 4368

Step-by-step explanation:

FG:

[tex]\frac{4}{5}[/tex] = [tex]\frac{12}{x}[/tex]  Since I have to multiply 3 x4 to get 12, I will multiply 5 by 3 to get 15

GH:

[tex]\frac{4}{5}[/tex] = [tex]\frac{16}{x}[/tex]  Since I have to multiply 4 by 4 to get 16, I will multiply 5 by 4 to get 20.

HF:

[tex]\frac{4}{5}[/tex] = [tex]\frac{8}{x}[/tex] Since I have to multiply 4 by 2 to get 8, I will multiply 5 by 2 to get 10

Given:

The locations of the two points are (-3 , -8) and (3 , -8).

To find:

The relation between two points.

Solution:

From the given points (-3 , -8) and (3 , -8), it is clear that the y-coordinates are same but the sign of x-coordinates are opposite.

If a figure is reflected across the y-axis, then we change the sign of x-coordinate and the y-coordinates remain same, i.e.,

[tex](x,y)\to (-x,y)[/tex]

For (3,-8),

[tex](3,-8)\to (-3,-8)[/tex]

So, it is reflection across the y-axis.

Therefore, the correct option is C.

Answer:

reflection across the x-axis

The surface area is [tex]4\sqrt{2} \pi[/tex] units.

This problem is related to the triangle and solid figures.

If we rotate a triangle alongside one of its legs then it's going to shape a cone and the radius of the cone might be the duration of the bottom of the triangle and the hypotenuse of the triangle may be the slant peak of the cone.

The period of the the triangle legs is given to be 2 units.

Length of the hypotenuse=[tex]\sqrt{2^{2} +2^{2} }[/tex]

                                        = [tex]2\sqrt{2}[/tex] units.

Now the area of the cone is given by [tex]\pi rl[/tex] where r is the radius of the cone and l is the slant height of the cone.

Surface area of cone = [tex]\pi *2*2\sqrt{2}[/tex]

                                  = [tex]4\sqrt{2} \pi[/tex] units

So, the surface area of cone is [tex]4\sqrt{2} \pi[/tex] units.

Given:

The equation [tex]T=15n+12[/tex] represents the total amount T, in dollars, Salim will pay for n tickets.

To find:

What does 12 represent in the equation?

Solution:

The vendor charges a one-time service fee for processing the purchase of the tickets.

We have, the equation

[tex]T=15n+12[/tex]

Here, 15 is the coefficient of n and 12 is constant.

If n is number of tickets then 15 must be the price of each ticket.

12 is free from variable and it is fixed. So, it represents one-time service fee for processing the purchase of the tickets.

Therefore, 12 represents that one-time service fee for processing the purchase of the tickets is $12.

The total cost of wrapping for both fishes are given by 4.5x + 2 and 5x respectively.

An equation is used to show the relationship between numbers and variables. An equation can be linear, quadratic depending on the degree.

Let x represent the number of pounds of the fish.

For the first fish, cost = 4.5x + 2

For the second fish, cost = 5x

The total cost of wrapping for both fishes are given by 4.5x + 2 and 5x respectively.

Step-by-step explanation:

Best advice: make a sketch (which I can't do here).

When you reflect in the x axis, only the y value changes...so (3, -4) reflects to (3,4).

Translating down (i.e. in the negative direction) again means the x value (the abscissa) doesn't change, only the y value (the ordinate)...so the final value of the point is (3,1).
