Answer:

I'm pretty sure its w=128

Step-by-step explanation:

so what i did was the inverse operation which the opposite of ÷4 is ×4 so 4 is already canceled out so then all you have left is 32×4 which is 128. Hope this helps

Answer:

the answer is D

Step-by-step explanation:

makes sense...

Answer:

9.099 seconds

Step-by-step explanation:

The rock hits the surface of the moon when is t is 0.

[tex]-t^2 + 8t + 10 = 0\\t^2 - 8t - 10 = 0[/tex]

Use the quadratic formula

t = -1.099 and 9.099

Since time can't be negative, the answer is t = 9.099

Answer:

c

Step-by-step explanation:

Answer:

a. 10.4m above the cliff

b. 18.4m below the cliff

c. Os or 3.1s

d. 5.1s

a) The rock be 10 m above the cliff after two seconds.

b) The rock be 20 m below the cliff after 4 seconds.

c) After 3 second it again be at the same level you threw it.

d) After 5 second it hit the water, 50 m below the cliff.

What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.  

Since, The formula for the distance,

s = ut - 1/2 gt²

Where, s is distance of an object.

u is initial velocity.

t is time taken by object.

Now,

a) Given that;

t = 2 seconds , u = 15 m/sec , g = 10 m/s

Since, s = ut - 1/2 gt²

Substitute all values we get;

s = 15 × 2 - 1/2 × 10 × 2²

s = 30 - 20

s = 10 m

Thus, The rock be 10 m above the cliff after two seconds.

b) Given that;

t = 4 second,

Then, s = ut - 1/2 gt²

s = 15 × 4 - 1/2 × 10 × 4²

s = 60 - 80

s = - 20

Hence, The rock be 20 m below the cliff after 4 seconds.

c) Given that;

s = 0 meter

Then, s = ut - 1/2 gt²

Substitute all the values,

0 = 15t - 1/2 × 10 × t²

15t - 5t² = 0

5t² - 15t = 0

5t ( t - 3) = 0

Gives, t = 0 second and t = 3second

So, After 3 second it again be at the same level you threw it.

d) Given that;

s = -50 m

Since, s = ut - 1/2 gt²

Thus, Substitute all the values we get,

- 50 = 15t - 1/2 × 10 × t²

15t - 5t² = -50

5t² - 15t - 50 = 0

5 (t² - 3t - 10) = 0

t² - 3t - 10 = 0

By using quadratic formula;

t = -(-3) ± √(-3)² - 4 × 1 × -10 / 2 × 1

t = 3 ± √9 + 40 / 2

t = 3 ± √49 / 2

t = 3 ± 7 / 2

Gives t = 3 + 7 / 2 = 5 second

and , t = 3 - 7/ 2 = -4/2 = -2 second

Thus, After 5 second it hit the water, 50 m below the cliff.

So,

a) The rock be 10 m above the cliff after two seconds.

b) The rock be 20 m below the cliff after 4 seconds.

c) After 3 second it again be at the same level you threw it.

d) After 5 second it hit the water, 50 m below the cliff.

Answer: 66

Step-by-step explanation:

From the question, we are informed that a player at a basketball camp set a goal to make 55% if his shots and that he has 120 attempts.

The number of shots that he would he need to make in order to reach his goal will be 55% of 120. This will be:

= 55% × 120

= 55/100 × 120

= 0.55 × 120

= 66

He would need to make 66 shots

Answer:

x < 45

Step-by-step explanation:

Let's call that number x. x/3 - 5 < 10, and we can add by five on both sides then multiply by 3 on both sides to get that x < 45.

Answer:

Discount:

20% is .2 as a decimal, so you multiply the value of 12 by .2

12(.2)=2.4

The discount is $2.40

Sale Price:

subtract 2.4 from the price of the original price

12-2.4=9.6

The sale price is $9.60

Answer:

Each can of soda will cost $0.37

Step-by-step explanation:

First you write 24/8.99 = 1/x because you are trying to find the cost for 1 soda

24/8.99 = 1/x

Then you cross multiply.

24*x  8.99*1

24x=8.99

Divide each side by 24

24x/24=8.99/24

x=0.374583

Round it to the nearest hundredths place.

x=0.37

Answer:

(1, 3 )

Step-by-step explanation:

Then (1, 3 ) is an ordered pair on the line

Answer:

8a^3

Step-by-step explanation:

Given that;

2^x = a, we want an expression for 8^(x + 1)

we have this as;

8^(x + 1) = 8^x * 8^1

8^x = (2^x)(3)

8^x is thus same as 2^3x

So replace 2^x by a

Thus, we have a^3

Multiply this by the 8 we had initially; that will give;

8 * a^3 = 8a^3

Step-by-step explanation:

"A set of numbers arranged in rows and columns so as to form a rectangular array."

"A matrix formed by combining the columns of two matrices to form a new matrix."

"The mathematical operations that are performed on rows of a matrix."

For given question,

We have been given an augmented matrix.

[tex]\begin{bmatrix}4 & 0 & -4& |& -8 \\0 & 1 & 0& |& -1 \\0 & 0 & 1& |& 3\end{bmatrix}[/tex]

We need to perform the row operation 4R3 + R1 → R1

To perform above row operation,

- First multiply the third row by 4. ([tex]4R_3[/tex])

- Add the new third row (4[tex]R_3[/tex]) with the first row.

- Then replace Row 1 with the result.

The resultant augmented matrix would be,

[tex]\begin{bmatrix}\bold{4} & \bold{0} & \bold{0}& |& \bold{4} \\0 & 1 & 0& |& -1 \\0 & 0 & 1& |& 3\end{bmatrix}[/tex]

That is,

[tex]\begin{bmatrix}4 & 0 & -4& |& -8 \\0 & 1 & 0& |& -1 \\0 & 0 & 1& |& 3\end{bmatrix} \xrightarrow{\text{4R3+R1}\rightarrow \text{R1}} \begin{bmatrix}\bold{4} & \bold{0} & \bold{0}& |& \bold{4} \\0 & 1 & 0& |& -1 \\0 & 0 & 1& |& 3\end{bmatrix}[/tex]

Now, we need to perform the row operation  [tex]\frac{1}{4}[/tex] R1 → R1 on the above resultant augmented matrix.

To perform above row operation,

- Multiply the Row 1 by the reciprocal of 4.

- Then replace Row 1 with the result.

The resultant augmented matrix would be,

[tex]\begin{bmatrix}4 & 0 & -4& |& 4 \\0 & 1 & 0& |& -1 \\0 & 0 & 1& |& 3\end{bmatrix} \xrightarrow{\frac{1}{4} \text{R1}\rightarrow \text{R1}} \begin{bmatrix}\bold{1} & \bold{0} & \bold{0}& |& \bold{1} \\0 & 1 & 0& |& -1 \\0 & 0 & 1& |& 3\end{bmatrix}[/tex]

Therefore,

[tex]\begin{bmatrix}4 & 0 & -4& |& -8 \\0 & 1 & 0& |& -1 \\0 & 0 & 1& |& 3\end{bmatrix} \xrightarrow{\text{4R3+R1}\rightarrow \text{R1}} \begin{bmatrix}\bold{4} & \bold{0} & \bold{0}& |& \bold{4} \\0 & 1 & 0& |& -1 \\0 & 0 & 1& |& 3\end{bmatrix}[/tex]

and,

[tex]\begin{bmatrix}4 & 0 & -4& |& 4 \\0 & 1 & 0& |& -1 \\0 & 0 & 1& |& 3\end{bmatrix} \xrightarrow{\frac{1}{4} \text{R1}\rightarrow \text{R1}} \begin{bmatrix}\bold{1} & \bold{0} & \bold{0}& |& \bold{1} \\0 & 1 & 0& |& -1 \\0 & 0 & 1& |& 3\end{bmatrix}[/tex]
