Complete the square.................
Alenkinab [10]2 years ago

We can use completing the square.We add 16 and subtract 7 to both sides. Now we get m^2+8m+16=9. The left sides becomes (m+4)^2=9. Taking the square root of both sides and subtracting 4 we get -1 and -7.

At the local department store sweaters have been reduced to $15 this price is at 75% of the original price for sweaters given th
BartSMP [9]
Since 75% = 3/4
then $15 = 3/4 of the original price

Divide 15 ÷ 3 to get the 25% of the original price
(1/4 of the price)

15 ÷ 3 = 5

$5 is the 25% of the original price

so, if 25% + 75% = 100%
then $5 + $15 = $20

The original price for the sweaters was $20.

Which number in the monomial 125x^18y^3z^25 needs to be changed to make it a perfect cube
Oksana_A [137]

Hi,

You just have to change z^25 to z^24 or z^27.

125x^{18}y^3z^{24}=(5x^6*y*z^8)^3

On a bicycle trail, the city is painting arrows like the one shown below: Upper pointing arrow with height of 11 and length of 9
Studentka2010 [4]

The image of the arrow is missing, so i have attached it.

Answer:

A_t = 69.5 cm²

Step-by-step explanation:

In a second image attached, I have divided the arrow into triangle and rectangle.

From the second image,

A1 is area of triangle while A2 is area of rectangle

Area of triangle is; A1 = ½bh

Our triangle base is given as 9 cm.

To get the height, we will subtract the rectangle height of 8 cm from the total arrow height.

Thus; height of triangle; h = 11 - 8 = 3cm

Thus;

A1 = ½ × 9 × 3

A1 = 13.5 cm²

Formula for area of rectangle is;

A2 = length × breadth

A2 = 8 × 7

A2 = 56 cm²

Thus, total area of arrow is;

A_t = A1 + A2 = 13.5 + 56

A_t = 69.5 cm²

What is the image of (5, 4) when it is<br> rotated 180° about the origin?
nadezda [96]

Answer:

(-5, -4)

Step-by-step explanation:

When you rotate a point 180 degree about the origin, the x coordinate will becomes its opposite, as well as the y-coordinate.

So, as an example, if a point was at -3, 7, after a 180 degree rotation, it would be 3, -7.
