Answer:

See explanation

Step-by-step explanation:

Let (x,y) be the coordinates of the point which has to be dilated with the scale factor of k with the center of dilation at point (0,0) (the origin).

The dilation with the scale factor k and the center of dilation at the origin has the rule

(x,y)\rightarrow (kx,ky)

So, you have simply to multiply each coordinate of the point by k to get the image's coordinates.

I thought doubling everytime except for the number 19000 because if you do 250 × 2 = 500 so then you do 500×2=1000.

Cory made 4,500 g of candy. He saved 1 kg to eat later. He divided the rest of the candy over 7 bowls to
Olenka [21]

Answer: 500 g of candy in each bowl

Step-by-step explanation:

1,000 g = 1Kg

4,500 g - 1,000 g =  3,500 g of candy were divided over 7 bowls:

Each bowl contains = 3,500 g➗7 bowls = 500 g candy/bowl

Answer: 500 g of candy in each bowl

          - 4 x³ + x² - 4 x
            4 x³        + 4 x

Find the equation of the line using the point-slope forumla. Write the final equation using the slope-intercept form. parallel t
Greeley [361]

Answer:

see explanation

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

y = 3x - 2 is in this form with slope m = 3

• Parallel lines have equal slopes

Hence the slope of the parallel line = 3

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

here m = 3 and (a, b) = (- 3, - 14), hence

y + 14 = 3(x + 3) ← in point- slope form

Distribute and simplify

y + 14 = 3x + 9 ( subtract 14 from both sides )

y = 3x - 5 ← in slope- intercept form

if a tree casts an 8 meter shadow, and the angle from the ground to the tree is 30 degrees, what is the approximate height of th
Virty [35]
Using SohCahToa, we can find the height of the tree. Let the tree height be h. 8m is adjacent to the 30° angle.
\tan(30)  =  \frac{h}{8}  \\ h = 8 \tan(30)  \\ h = 4.62
The answer is A) 4.6 m
