A football is punted from a height of 3. 5 feet about the ground with an initial velocity of 45 feet per second. This situation can be represented by the function −16t2 + 45t + 3. 5 , where t is the number of seconds elapsed since the football was kicked. If the football is caught at a height of 5. 5ft on the ball’s descent, when was the football in the air at that height?

Answer:

1. and 2. Reason) Given

3. Statement) Angle ABD is congruent to CBD

4.) BD is congruent to BD

5.) ΔDAB is congruent to ΔDCB due to SAS

Answer:

Step-by-step explanation:

Twice a number n → 2 · n = 2n

Twice a number n plus 4 → 2n + 4

The product of 4 and a number n → 4 · n

Twice a number n plus 4 is the product of 4 and a number n → 2n + 4 = 4n

Answer:

6/11

Step-by-step explanation:

After taking 2 counters with no replacement, that only one of these is white. We will see that the probability is 6/11.

Given that;

there are 11 counters, 5 of them are white, 6 are not white

First we take the white one, the probability is equal to the quotient between the number of white counters and the total number of counters, so we have:

p = 5/11

And, also notice that there are 2 permutations:

first white, then non-white.

first non-white, then white.

So we need to add a factor 2.

P = 2*p*q = 2*(5/11)*(6/10) = 6/11

The probability is 6/11

We can also Do:

11/11 = Whole

11 - 5 = 6

Hence, Answer = 6/11

Answer:

1 is function and 2 is not function.

Step-by-step explanation:

If a linear equation has one output for ever input it is a function. if you give a inout and you get two outputs, it is not a function. the input or x value is called domain and the output or y value is range.

Answer:

Step-by-step explanation:

Starting at 0:8 for every time the x(or the 0) changes up by 1 the y(or the 8) goes down by one

4) Dmytro drank more juice

5) Henrietta is older

Step-by-step explanation:

4)

Dmytro drank 7/4 bottles which is 1.75 bottles

Jitka drank 1 1/2 bottles which is 1.5 bottles

So, Dmytro drank more juice

5)

Henrietta is 7 2/3 years old which is 7.66

Jagdeep is 65/12 years old which is 5.41

So, Henrietta is older

Answer:

that number is 11

Step-by-step explanation:

if you call that number n, you can make the following equation:

40 - 5n = -15

add 5n to both sides of the equation

40 = -15 + 5n

add 15 to both sides of the equation

55 = 5n

divide both sides by 5

11 = n

Answer:

11

Step-by-step explanation:

I put 11 and got it right

For h(x)

The function is

For g(x)

Line passes through

Observe

So

The function is

Now

k(x)

Answer:

Hope this helps! :)

Step-by-step explanation:

We can find the equations of the given functions as follows:

The linear function is h(x) = 2x + 1

The exponential function is g(x) = 2^x

To find k(x) = g(x) * h(x), we multiply the two functions:

k(x) = g(x) * h(x)

k(x) = 2^x * (2x + 1)

k(x) = 2^(x+1) * (x + 1/2)

So, the option that gives the formula of k(x) is:

k(x) = 2^(x+1) * (x + 1/2)

Therefore, the answer is:

k(x) = 2^(x+1) * (x + 1/2)

Answer:

the difference of 2 times d minus 3= 6

4 added to the difference of d minus 3= 4

the difference of d minus 3 divided by 2= 0

the quotient of 12 divided by the difference of 3 times d minus 3= 2

Step-by-step explanation:

2 times 3 equals 6. 3 minus 3 equals 0. 6-0=6

d minus 3 equals 0. 4+0 equals 4

3 minus d equals 0. 0 divided by two is 0

3 times d= 9. minus 3 = 6. 12 divided by 6 = 2

Step-by-step explanation:

Original rectangle

L = 2*w

w = w

New rectangle

2w + 4

w - 3

Area New rectangle

(2w + 4)(w - 3) = 600               Remove the brackets

2w^2 - 6w + 4w - 12 = 600     Combine the left

2w^2 - 2w -  12 = 600             Subtract 600 from both sides

2w^2 - 2w - 600 - 12 = 0        Combine

2w^2 - 2w - 612 = 0                This factors.

(w- 18)(w + 17) = 0

w +  17 will produce nothing useful. What is - 17 m ? Can you measure it?

w = 18

Original Triangle

w = 18

Answer:

$-8295

Step-by-step explanation:

13.5% of 23700 is 3199.5. 3199.5 x 10 years is 31,995 so

23,700-31,995 is -8295.

Step-by-step explanation:

Answer:

(a - 2b - 3c)(a - 2b + 3c)

Step-by-step explanation:

a² + 4b² - 4ab - 9c²

= (a - 2b)² - 9c² ← difference of squares which factors in general as

a² - b² = (a - b)(a + b) , then

(a - 2b)² - 9c²

= (a - 2b)² - (3c)²

= (a - 2b - 3c)(a - 2b + 3c)

Answer:

b = 8

Step-by-step explanation:

-2 + 8(b + 3) = 86

Open the parenthesis

-2 + 8b + 24 = 86

Combine like terms

8b + 22 = 86

Subtract 22 from both sides of the equation

8b = 64

Divide both sides by 8

b = 8

Answer:

A

Step-by-step explanation:

dilation and rotation

Answer:

The easiest way to solve this is by elimination.  

3x - y = 6  

6x + y = 21

Since you have a negative and positive y with the same coefficients (1), they cancel, and you add the other terms so it would look like:

9x = 27  

Then solving for x leaves you with x = 3  

Then you take the x value of three and plug it into to either of the equations, so  

3(3) - y = 6

9 - y = 6  

subtracting 9  

-y = -3  

then dividing by -1  

y = 3  

so the solution is x = 3 y = 3 or (3,3)  

Step-by-step explanation:

Answer:

15

Step-by-step explanation:

Add 3x + 6x, and execute the y, then -6 from 21 and you got ur answer of 15!

Answer and explanation:

Original cost of jeans =$64

Markdown by 50%= 0.50*64= $32

Additional discount by clearance sign 50% =0.50*32= $16

Therefore I disagree with Johnny. First the original price $64 was reduced by half of the price 50% of $64 =$32. Secondly the new price $32 is then also reduced by half of it 50% giving us $16. Therefore the discounts did not wipe off all the price as suggested by Johnny.
