W is located at -2 and three on a coordinate plane. W is reflected over the X axis to create. W1 point W1 is been reflected over

amid [387]

Answer:

Step-by-step explanation:

W is located at -2 and three on a coordinate plane, it means W (-2, 3)

W is reflected over the X axis to create W1, we apply the rule: W(x, y) -->W1 (-x, y) => W1 ( 2, 3)
W1 is been reflected over the Y axis to create W2, we apply the rule: W1(x ,y) --->W2 (x, -y) => W2 = (2, -3)

So the location of W2 on the plane is (2, -3)

The height of a flare fired from the deck of a ship in distress can be modeled by h=-16t^2+104t+56, where h is the height of the

grin007 [14]

Answer:

7 seconds.

Step-by-step explanation:

We have been given that the height of a flare fired from the deck of a ship in distress can be modeled by $h=-16t^2+104t+56$ , where h is the height of the flare above water and t is the time in seconds.

The ball will hit the ground, when height will be 0 meters, so we will equate $h=0$ to find the time when ball will hit the ground as:

$-16t^2+104t+56=0$

Using quadratic formula, we will get:

$t=\frac{-104\pm\sqrt{104^2-4(-16)(56)}}{2(-16)}$

$t=\frac{-104\pm\sqrt{10816+3584}}{-32}$

$t=\frac{-104\pm\sqrt{14400}}{-32}$

$t=\frac{-104\pm120}{-32}$

$t=\frac{-104+120}{-32}\text{ or }t=\frac{-104-120}{-32}$

$t=\frac{16}{-32}\text{ or }t=\frac{-224}{-32}$

$t=-\frac{1}{2}\text{ or }t=7$

Since time cannot be negative, therefore, it will take 7 seconds for the flare to hit the ground.

Enter numbers to write 13,000 in scientific notation. 13,000=1.3 × =1.3×10

TiliK225 [7]

Answer:

104 = 10,000 x 1.3 = 13,000

Step-by-step explanation:

step 1

To find a, take the number and move a decimal place to the right one position.

Original Number: 13,000

New Number: 1.3000

Step 2

Now, to find b, count how many places to the right of the decimal.

New Number: 1 . 3 0 0 0

Decimal Count: 1 2 3 4

There are 4 places to the right of the decimal place.

Step 3

Building upon what we know above, we can now reconstruct the number into scientific notation.

Remember, the notation is: a x 10b

a = 1.3 (Please notice any zeroes on the end have been removed)

b = 4

Now the whole thing:

1.3 x 104

Step 4

Check your work:

104 = 10,000 x 1.3 = 13,000

If the lines are parallel with angle a measuring 5x + 8 and angle b measuring 8x - 7, the measure of angle a would be ___ degree

Mandarinka [93]

The value of angle a will be 33°.

It should be noted that when we've parallel lines, then the angles will be equal. In this case, the value of angle a will be equal to that of angle b and this will be:

5x + 8 = 8x - 7.

Collect like terms .

8x - 5x = 8 + 7

3x = 15

Divide both side by 3

3x/3 = 15/3

x = 5

Therefore, the value of angle a will be:

= 5x + 8

= 5(5) + 8

= 25° + 8°

= 33°

The measure of angle a is 33°.

Jayden is running laps at track practice. The track is 2/5 kilometers around. Jayden runs 1 lap in 2 minutes. How many minutes d

Tom [10]

Answer:

0.08 minutes for a kilometer.

Step-by-step explanation:

If the track is 25 kilometers, and he runs 25 kilometers in 2 minutes, he runs a kilometer in 2÷25 minutes or 0.08 minutes which is 4.8 seconds.

I'm pretty sure the track isn't 25 kilometer or he can't run a lap in 2 minutes. But if so, the answer is 0.08 minutes.
