Answer:

The ball will be able to reach the 16 ft.

Step-by-step explanation:

In order to calculate if the ball will be able to reach that height, we must make "h" equal to 16, if there's a real positive solution, then the ball will be able to reach it.

16 = -16t² + 35t

16t² - 35t + 16 = 0

t = [-(-35) +- sqrt((-35)² - 4*16*16)]/(2*16)

t = [35 +- sqrt(1225 - 1024)]/32

t = [35 +- sqrt(201)]/32

t = (35 +- 14.177)/32

t1 = 0.65071875

t2 = 1.5367

The ball will reach that height at 0.65 s and 1.53 s.

Step-by-step explanation:

Answer: 2 2/5

Turn -1 3/5 into an Improper Fraction

Multiply -1×5 and get -5. Now add 3 and get -8.

-1 3/5 = -8/5

Do Keep Change Flip

Keep: -8/5

Change: ÷ into ×

Flip: -2/3 into -3/2

Multiply

-8/5×-3/2=12/5

Simplify

12/5 = 2 2/5

Answer:

2 2/5

Step-by-step explanation:

see attached

A positive and a negative become a negative. First you convery the mixed fraction into an improper fraction, then you find the common denominator of all fractions, next step according to PEMDAS, you can add and subtract in any order you would like too.

1. -7 2/3 - 5 1/2 + 8 3/4

2. -23/3 - 11/2 + 35/4

3. -92/12 - 66/12 + 105/12 The common denominator is 12.

4. -92/12 - 66/12 = -158/12 A negative and a negative is addition but just add the negative sign.

5. -158/12 + 105/12 = -53/12 =

Answer= -4 5/12

This is my way of doing it but according to PEMDAS any other order of doing it is fine also!

Step-by-step explanation:

Answer:

Tuesday, 1: 30 pounds

Tuesday, 2: 40% of the apples

Tuesday, 3: x ( or any variable) + 8

Tuesday, 4: 9a-3b

Step-by-step explanation:

Since she weighs 38% of the normal weight, you multiply the decimal form to the original weight, which is 78. So .38 multiplied by 78 is 29.64, and rounding it to the nearest pound would make it go up to 30.

38%=.38

.38 x 78=29.64

29.64 rounded = 30

If 3/5 of the apples are ripe, that means that 2/5 are not. An easy way to turn this fraction into a percent is to make the number out of 100. Since 5 x 20 is 100, you multiple both the numerator and denominator by 20. 2 x 20 is 40, 5 x 20 is 100, hence 40/100. The numerator will be the percentage.  

5/5-3/5 = 2/5

2/5 x 20/20 = 40/100

40/100 = 40%

The unknown score would become a variable, and since its increasing by 3 it is +8.

Since the perimeter is adding all sides, you'd add all of the equations. The 3a's times 3 would be 9a, and the -b would become -3b.

3a - b + 3a - b + 3a - b

9a - b - b - b

9a - 3b

The correct question is:

Brett is comparing the graphs of y = 2^x and y = 5^x. Which statement is true?

(1) The y-intercept of y = 2^x is (0,2), and the y-intercept of y = 5^x

is (0,5). [

(2) Both graphs have a y-intercept of (0,1), and y = 2^x is steeper.

(3) Both graphs have a y-intercept of (0,1), and y = 5^x is steeper.

(4) Neither graph has a y-intercept.

Answer:

(2) and (3) are true.

Step-by-step explanation:

The correct options are:

(2) Both graphs have a y-intercept of (0,1), and y = 2^x is steeper. Since X < 0

(3) Both graphs have a y-intercept of (0,1), and y = 5^x is steeper. Since X > 0

Step-by-step explanation:

Answer:

(x - 9.2)^2 + (y + 7.4)^2 = (5/3)^2

Step-by-step explanation:

We start with (x - h)^2 + (y - k)^2 = r^2.  The center is (h, k) and the radius is r.

Then we have:

(x - 9.2)^2 + (y + 7.4)^2 = (5/3)^2

The value of the matrix -k in the expression is [tex]\left[\begin{array}{ccc}2&-9&8\\-7&-11&-6\\-4&-4&3\end{array}\right][/tex]

The matrix is given as:

[tex]k = \left[\begin{array}{ccc}-2&9&-8\\7&11&6\\4&4&-3\end{array}\right][/tex]

Multiply both sides by -1

[tex]-1 * k = -1 * \left[\begin{array}{ccc}-2&9&-8\\7&11&6\\4&4&-3\end{array}\right][/tex]

Evaluate the right hand side

[tex]-1 * k = \left[\begin{array}{ccc}2&-9&8\\-7&-11&-6\\-4&-4&3\end{array}\right][/tex]

Evaluate the left hand side

[tex]-k = \left[\begin{array}{ccc}2&-9&8\\-7&-11&-6\\-4&-4&3\end{array}\right][/tex]

Hence, the value of -k in the expression is [tex]\left[\begin{array}{ccc}2&-9&8\\-7&-11&-6\\-4&-4&3\end{array}\right][/tex]

5(7+3x)-12=35+15x-12=15x+23

Answer:

Step-by-step explanation:

Multiply the 5 to the 7 and 3x--> 35 + 15x -12. Then add 12 to the -12, making it 0 (inverse operations), and add 12 to the 35 making it 47 + 15x. :) Then you would simply divide the 15 by 15x (making the variable by itself). your answer for x should be 47/15. :> If I helped, please mark brainliest!!

Answer:

39/100

Step-by-step explanation:

The question asks to find the probability that a dormitory resident

chosen at random from this group has had a flu shot, given that he is male.

As for that, the first thing to do is to look at the column where it says male.

Male:

39-Had Flu Shot

12-Did not have Flu Shot

Since the question is asking for the total number of males who did get a flu shot, it would be 39.

Lastly, to find probability, you have to use part over whole. The part would be 39. The whole would be the number of people selected to be tested. Therefore, the whole would be 100. That is why the probability that a dormitory resident chosen at random from this group has had a flu shot, given that he is male would be 39/100.
