dont play with me just answer the question

Since there are 86400 seconds / day

& light travels at 3 x 10⁵ kilometers / second

Then kilometers the light travels in a day

  = (86400 seconds / day) × (light travels at 3 x 10⁵ kilometers / second)

  = 2.59 × 10¹⁰ kilometers/day

Note:

We know that we have to multiply because the unit 'seconds per day' has the seconds in the numerator, while the unit 'kilometer per second' has the seconds in the denominator, so to cancel we would have to multiply. This gives us the unit we are looking for 'kilometeres per day'.

Answer:

x=13

z=79

Step-by-step explanation:

The angles given are supplementary. This means that when added their sum will be 180. So add the 2 expressions together and set them equal to 180.

Then, you have to find z. The angle z is congruent to the angle with the measure (8x-25). This is because they are vertical angles, and therefore congruent. So, plug 13 into the expression, 8(13)-25=79 degrees. Since that angle equals 79, z must also equal 79.

Answer:

B.

y = −5(x + 4)^2 − 3

Step-by-step explanation:

Use the vertex and another point on the parabola to find the value of a. Then substitute the vertex (−4, −3) and a into the vertex form, y = a(x − h)2 + k.

Answer:

4

Step-by-step explanation:

If you increase the scale factor by 4, the sides become:

L= 2×4 = 8

W= 3×4 = 12

Now to find the new area:

8 × 12 = 96cm^2

So, a scale factor of 4 would give the rectangle a scale factor of 96.

Hope this helps and have a nice day!

A quadratic equation is in the form of ax²+bx+c. The solution of the given quadratic equation is 2 and -5.

A quadratic equation is an equation whose leading coefficient is of second degree also the equation has only one unknown while it has 3 unknown numbers. It is written in the form of ax²+bx+c.

Given the quadratic equation x²+3x-10=0, the solution to this equation can be done as shown below.

x² + 3x - 10 = 0

Keep x terms on the left and move the constant to the right side by adding it on both sides,

x² + 3x = 10

Take half of the x term and square it,

x = (3/2)² = 9/4

Then add the result to both sides

x² + 3x + (9/4) = 10 + (9/4)

Combine terms on the right,

(x + 3/2)² = 49/4

Taking under root,

x + 3/2 = ± 7/2

Now,

x = 7/2 - 3/2 = 2

x = -7/2 - 3/2 = -5

Hence, the solution of the given quadratic equation is 2 and -5.
