Melissa drops a tennis ball from the roof of a building that is 256 feet
high. How long does it take the tennis ball to hit the ground?

Answer:
Step-by-step explanation:
To solve this problem you need the function
h(t) = -16t2 + v0t + h0
where t = time
v0 is the initial velocity, which in our case is 0
h0 = initial height, which in our case is 256
h(t) = 0 since we want to know when the ball will hit the ground.
0 = -16 t2 + 256
And we can solve for t
If we rearrange the terms we see that this is a difference of 2 squares
0 = 256 - 16t2
0 = (16-4t)(16+4t)
Setting each factor = 0
16-4t=0 16+4t=4
t = 4 t = -4
The second solution is discarded as time cannot be negative.
So the ball will hit the ground in 4 seconds.

The 17 students on the varsity basketball team want to raise 857.11 to buy new game jerseys,they have already raised 218.25,if each student raises the same amount,how much more money must each other raise?
Answer:Each of the 17 students will need to raise 37.58 each
Step-by-step explanation:
Total amount needed to be raised =857.11
Amount of money already raised =218.25,
Amount of money required to complete the amount needed to be raised =857.11 -218.25=638.86
Since there are 17 students to raise the money, Each student will raise
638.86/17=37.58
Each of the 17 students will need to raise 37.58 each to complete the money
write the number into 3 significant figures 7.00956
=================================================
Explanation:
Use a marker to highlight the first three digits on the left. That would be the 7, 0 and 0.
The digit just to the right of that second "0" is the digit "9". Since this 9 is larger than 5, we'll bump the 7.00 up to 7.01
The 0 in 7.01 is significant because it's between two nonzero values. So we have three sig figs here.

what is the determinant of matrix |-8|?
Given:
The matrix is [tex][-8][/tex].
To find:
The determinant of given matrix, i.e, [tex]|-8|[/tex].
Solution:
If a matrix is A of order [tex]1\times 1[/tex], then the value of the determinant of that matrix is equal to the element of that matrix.
For example: Let A be the matrix of order [tex]1\times 1[/tex].
[tex]A=[a][/tex]
Then,
[tex]|A|=a[/tex]
The given matrix is [tex][-8][/tex]. So, the determinant of given matrix, i.e, [tex]|-8|[/tex], is
[tex]|-8|=-8[/tex]
Therefore, the value of determinant of given matrix is -8.

There exist two complex numbers $c$, say $c_1$ and $c_2$, so that $3 + 2i$, $6 + i$, and $c$ form the vertices of an equilateral triangle. Find the product $c_1 c_2$ in rectangular form.
The product $c_1 c_2$ in rectangular frame is [tex]\$10 e^{i(2\theta \pm \frac{pi}{3})}\$.[/tex]
How to find the product $c_1 c_2$ in rectangular formLet $c_1$ and $c_2$ be the two complex numbers that frame an even triangle with $3+2i$ and $6+i$.
The dispose of between two complex numbers $a$ and $b$ is given by $|b-a|$. Since the triangle is even, the wipe out someplace in the scope of $3+2i$ and $6+i$ ought to be equivalent to the underlying venture with to the kill among $3+2i$ and $c$, conjointly make back the underlying speculation with to the take out among $6+i$ and $c$.
So, we have the following conditions:
$|6 + i - (3 + 2i)| = |c - (3 + 2i)|$
$|6 + i - (3 + 2i)| = |c - (6 + i)|$
Tackling these conditions, we get:
$|3 - i| = |c - (3 + 2i)|$
$|3 - i| = |c - 6 - i|$
Presently, let's discover the esteem of $c$:
$|c - (3 + 2i)| = |3 - i|$
[tex]\$|c - (3 + 2i)| = \sqrt{(3-0)^{2} + (-1-0)^{2} = \sqrt{10}\$[/tex]
So, [tex]\$c - (3 + 2i) = \pm \sqrt{10} e^{i\theta}\$[/tex], where [tex]\$\theta\$[/tex] is the point between the positive genuine hub and the line interfacing $3+2i$ and $c$?
Presently, let's discover the esteem of $c$ utilizing the moment condition:
$|c - (6 + i)| = |3 - i|$
[tex]\$|c - (6 + i)| = \sqrt{(3-0)^{2} + (-1-0)^{2} = \sqrt{10}\$[/tex]
So, [tex]\$c - (6 + i) = \pm \sqrt{10} e^{i\theta'}\$[/tex], where [tex]\$\theta'\$[/tex] is the point between the positive genuine hub and the line interfacing $6+i$ and $c$?
Since the triangle is equilateral, $theta$ [tex]\$\theta'\$[/tex] must vary by [tex]\$\pm[/tex] [tex]\frac{\pi}{3}\$.[/tex]
Presently, let's discover the item $c_1 c_2$:
$c_1 c_2 = (c - (3 + 2i))(c - (6 + i))$
$c_1 c_2 =[tex](\pm \sqrt{10} e^{i\theta})(\pm \sqrt{10} e^{i(\theta \pm \frac{\pi}{3})})\$[/tex]
$c_1 c_2 = [tex]10 e^{i\theta} e^{i(\theta \pm \frac{\pi}{3})}\$[/tex]
$c_1 c_2 = [tex]10 e^{i(2\theta \pm \frac{\pi}{3})}\$[/tex]
So, the item $c_1 c_2$ in rectangular frame is [tex]\$10 e^{i(2\theta \pm \frac{\pi}{3})}\$.[/tex]

----------❥︎XxYunaKoharuChanxXAn angle measures 110.8° more than the measure of its supplementary angle. What is the measure of each angle?
Answer:
34.6 and 145.4
Step-by-step explanation:
x+(x+110.8) = 180
2x= 180-110.8
2x= 69.2
x= 34.6
Measure of each angle:
x= 34.6
x+110.8 = 34.6 + 110.8 = 145.4

Grace needs to buy a new printer. The printer she wants has a price tag of $60. She has a 25% off coupon and $50 in her bank account. If she must pay 6.75% sales tax, will she have enough money to buy the printer? If yes, how much will she have left over? If no, how much is she short?
Answer:
Yes, she will have $1.96 left
Step-by-step explanation:
Initial cost : $60
Discount : 25%=0.25
Calculating discount : 60 * 0.25 = 15
Calculating cost after discount : 60-15 = 45
Sales tax : 6.75%=0.0675
Calculating sales tax : 45 * 0.0675 = 3.0375≈$3.04
Calculating final cost : 45+ 3.04 = $48.04
Can she buy the printer : 50 - 48.04= $1.96
Answer : yes
Yes, she has enough money to buy the printer. Then the balance of her account will be $ 1.9625.
What is percentage?The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol 'percent' is used to symbolize it.
Grace needs to buy a new printer.
The printer she wants has a price tag of $60.
She has a 25% off coupon and $50 in her bank account.
If she must pay 6.75% sales tax.
Then the price of the printer after the discount of 25% and the sales tax of 6.75% will be
Cost = $ 60 x (1 - 0.25) x 1.0675
Cost = $ 60 x 0.75 x 1.0675
Cost = $ 48.0375
Yes, she has enough money to buy the printer.
Then the balance of her account will be
Balance = $ 50 - $ 48.0375

A $840
B $3,360
C $15,360
D $33,600
The yearly profits of a company are shown in the table.
Which answer describes the average rate of change from Year 2 to Year 4?
A Profits increased by an average of $10,600 per year
from Year 2 to Year 4.
B Profits increased by an average of $21,600 per year
from Year 2 to Year 4.
C Profits decreased by an average of $21,600 per year
from Year 2 to Year 4.
D Profits decreased by an average of $10,600 per year
from Year 2 to Year 4.
Answer:
Step-by-step explanation:
Hi, Emily. The average rate of change can be calculated by adding all the profits together and dividing by the different profits (4 profits all together A to D) so 10,600+21,600+-21,600+-10,600= 0
0/4= 0
So we can best describe this as 0 or nothing at all as it hasnt changed from year 2 to 4.

Sabiendo que 16x10=160¿como resolverías, sin hacer la cuenta escrita los siguientes calculos?A_16x20=
Answer:
A_16x20=320
Step-by-step explanation:
Esto se puede hacer fácilmente de 2 formas.
1) 20 se puede dividir en un múltiplo de 10 y luego multiplicar
16 x 20 =16 x 10 x 2 = 160 x 2 = 320
2) Uso de cero.
Cualquier cosa multiplicada por cero da un cero y luego multiplicar el otro número da el resultado.
16 x 20 = (16 x 2) * 10 = (32) 10 = 320
Así que separamos el cero añadiéndole un 1, lo que lo convierte en 10 y obtenemos el mismo resultado.
This can be easily done in 2 ways .
1) 20 can be broken into a multiple of 10 and then multiplied
16 x 20 =16 x10 x 2=160x 2= 320
2) Use of zero.
Anything multiplied with zero gives a zero and then multiplying the other number gives the result.
16 x 20 = (16x 2) *10= (32)10= 320
So we separated the zero by adding a 1 to it thus making it 10 and we get the same result.

Courtney would like to buy a new phone for $680. So far, she has saved $240. If she earns $8 an hour
babysitting, how many hours will she need to work to be able to buy the phone?
Answer:
she will need to work for 55 hours to buy the phone
Step-by-step explanation:
680 - 240 = 440
that's how much more she needs
449 ÷ 8 = 55
and that's the answer
55
hope that helped
Answer:
55 hours
Step-by-step explanation:
Well first we need to set up the equation
We know she needs 680$ to buy the phone so the equation must be equal to 240
She has 240 and earns 8 dollars per hr so were finding out how many hours of work is needed to be able to buy the phone
Represent the number of hours worked by "x"
Set the equation up as
240 + 8x = 680
Add -240 to both sides of the equation to make 240 be 0 and 680 be 440
8x = 440
divide both sides of equation by 8 to get what x equals
x=55
She needs to work 55 hours
