Answer:

a) The maximum height that the ball reaches is 73.1 meter

b ) The time elapsed when the ball reaches its maximum height of flight = 2.2 seconds

Step-by-step explanation:

The complete question is

During a high school baseball tournament, Lando hits a pitch and the baseball stays in the air for 4.42 seconds. The function h(t) = -5t2 + 22t + 0.5 describes the height over time, where h is its height, in meters, and t is the time, in seconds, from the instant the ball is hit. a. What is the maximum height the ball reaches? b. What will be the time elapsed when the ball reaches its maximum height of flight?

Solution:

For maximum height

[tex]\frac{dh}{dt} =0[/tex]

[tex]\frac{d(5t^2 + 22t + 0.5)}{dt}\\ 10t + 22 = 0\\t = 2.2[/tex]seconds

a) Maximum height

[tex]5 * t^2 + 22t + 0.5[/tex]

[tex]= 5 * 2.2 *2.2 + 22 * 2.2 + 0.5 \\= 73.1[/tex]

b) Time elapsed when the ball reaches maximum height is 2.2 seconds

Answer & Step-by-step explanation:

Let's have

C = Creepers

B = Balloons

1) 6C + 20B = 11.9  

2) 2C + 15B = 6.05

Eliminate

16C + 20B = 11.9 x3  

-2C + 15B = 6.05 x4

18C + 60B = 35.7  

-8C + 60B = 24.2

10C/10 = 11.5/10  

C = 1.15

Answer:

[tex]\sqrt{49}[/tex]=7

The value of the square root of the number 49 is 7.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs. An nth root of a number x is a number r that when raised to the power n yields x.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that the number is 49 and the square of the number is calculated as,

E = √49

E = √ ( 7 x 7 )

E = 7

b=21

Step-by-step explanation:

For this problem we need to use Pythagorean theorem (a^2+b^2=c^2):

20^2+b^2=29^2

Simplify the squares:

400+b^2=841

Subtract 400 from both sides:

b^2=441

Take the square root of both sides:

Answer:

There is NO mode.

The range is 6.

Step-by-step explanation:

Mode is the most frequent number and in this case there are no repetitive numbers.

Range is the Max Number minus the Minimum Number. So in this case 24-18 which equals 6.

Answer:

I believe the measurement of angle 5, would be 114.

Step-by-step explanation:

We can solve this by using alternate interior angles. First we must find the other alternate interior angle for angle 5. To do this we take 66 and subtract it from 180. We now find that the angle adjacent to the angle measuring 66 degrees is equal to 114 degrees.  Now, the angle we just found the measurements for, is the alternate interior angle for angle 5. Therefore, since they are alternate interior angles, angle 5 is equal to 114 degrees.

I hope this helps!

Answer:

The two missing angles are 20 and 30 degrees.

Step-by-step explanation:

Quadrilaterals have four interior angles that add up to 360 degrees.

So we have two angles that are 240 degrees and 70 degrees.

If 240 + 70 = 310

That means the other two angles added together must be equal 50.

Because 360 - 310 = 50

So their ratio is 2:3 which means they have five equal parts.

Which would mean 50/5 = 10

2 x 10 = 20

3 x 10 =30

This means the missing angles are 20 and 30 degrees.

Given:

A circle with center O.

[tex]m\angle MOP=45^\circ, m\angle PON=85^\circ[/tex].

To find:

The measure of arc MN.

Solution:

We know that,

[tex]m\angle MON=m\angle MOP+m\angle PON[/tex]

[tex]m\angle MON=45^\circ+85^\circ[/tex]

[tex]m\angle MON=130^\circ[/tex]

The central angles in equal to the measure of the corresponding arc.

[tex]Arc(MN)=m\angle MON[/tex]

[tex]Arc(MN)=130^\circ[/tex]

Therefore, the measure of arc MN is 130 degrees.

Answer:

I only know B and C

Step-by-step explanation:

Part B)

2 (x+15) + 3x + 10+ 5x = 180        2x + 30 + 3x + 10 +5x = 180           10 +40 = 180

- 40 -40            10x divided by 10 = 140 divided by 10             x= 14

Part C)

A = 2 (x + 15) = 2 (14 + 15) = 2 * 29 = 58 degrees

< B = 3 x + 10 = 3 * 14 + 10 = 52 degrees

< C = 5 x = 5 * 14 = 70 degrees

Answer:

Step-by-step explanation:

The probability that the spinner will land on yellow both times is 1/16.

Probability is the chance of occurrence of a certain event out of the total no. of events that can occur in a given context.

Given, A spinner is divided into 4 equal sections colored red, blue, and green.

So, N(S) = 4 and N(R) = 1, N(B) = 1, N(G) = 1 and N(Y) = 1.

Conditional probability is a term used in probability theory to describe the likelihood that one event will follow another given the occurrence of another event.

As the events of getting yellow both times is independent,

The likelihood that the spinner will hit yellow twice is,

P(Y, Y) = P(Y)×P(Y).

P(Y, Y) = (1/4)×(1/4).

P(Y, Y) = 1/16.

Step-by-step explanation:

[tex]equation: \frac{x}{140} = \frac{30}{100} \\reduced: 100x = 4200\\ solved: \frac{100x}{100} = \frac{4200}{100} \\x = 42[/tex]

An equation is formed of two equal expressions. The equation that shows the relationship 30% of 140 is x is x=0.30×140.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Given that 30% of 140 is equal to x. Therefore, we can write,

[tex]\text{30\% of 140} = x\\\\\dfrac{30}{100} \times 140 = x\\\\x = 0.30 \times 140\\\\x=42[/tex]

Hence, the equation that shows the relationship 30% of 140 is x is x=0.30×140.
