The answer would be 6

Steps: The equation of a circle is (x – h)² <span>+ (y – k)</span>²<span> = r</span>²; since we are trying to find the radius we are going to focus on the r². Now if you look the equation has the 36 filled in as the r² so r² = 36; we now have to isolate the r to get the radius, how do we get the radius? We Square root the r² and 36. After we get r = 6, The radius is 6 units

Making coconut cookies. The recipe calls for 420 g of coconut and 120 g of sugar. Only has 252 g of coconut. How much sugar must
geniusboy [140]

Answer: 72 grams.

Step-by-step explanation:

Let be "s" the amount of sugar in grams that  must be used for 252 grams of coconut to keep the same ratio of coconut to sugar.

Knowing that in the recipe for the coconut cookies, should be 420 grams of coconut and 120 grams of sugar, and you only have 252 grams of coconut, you can set up this proportion to find "s":

\frac{420grams}{120grams}=\frac{252grams}{s}

Now, you need to solve for "s":

\frac{420grams}{120grams}=\frac{252grams}{s}\\\\s(\frac{420grams}{120grams})=252grams\\\\s=(252grams)(\frac{120grams}{420grams})\\\\s=72grams

deff fn [24]

Answer:

below

Step-by-step explanation:

You've been asked to use specific x-values. Simply replace the x in the equation for each of your x-values then graph.

first equation!!

(x,y)

y=-2x+5

x-value: -2

y=-2(-2)+5

y=4+5

y=9

(-2, 9)

x-value: -1

y=-2(-1)+5

y=2+5

y=7

(-1, 7)

x-value: 0

y=-2(0)+5

y=0+5

(0, 5)

x-value: 1

y=-2(1)+5

y=-2+5

y=3

(1, 3)

x-value: 2

y=-2(2)+5

y=-4+5

y=1

(2, 1)

second equation :)

(x,y)

y=x^2 +2

x-value: -2

y=-2^2 +2

y=4+2

y=6

(-2, 6)

x-value: -1

y=-1^2 +2

y=1+2

y=3

(-1, 3)

x-value: 0

y=0^2 +2

y=0+2

(0, 2)

x-value: 1

y=1^2 +2

y=1+2

y=3

(1, 3)

x-value: 2

y=2^2 +2

y=4+2

y=6

(2, 6)

third equation

(x,y)

y=√2 x+1

x-value: 1

y=√2 1+1

y=1+1

y=2

(1, 2)

x-value: 4

y=√2 4+1

y=2+1

y=3

(4, 3)

x-value: 9

y=√2 9+1

y=3+1

y=4

(9, 4)

x-value: 16

y=√2 16+1

y=4+1

y=5

(16, 5)

x-value: 25

y=√2 25+1

y=5+1

y=6

(25, 6)

fourth (last) equation :-)

(x,y)

y=4/x

x-value: -4

y=4/-4

y=-1

(-4, -1)

x-value: -2

y=4/-2

y=-2

(-2, -2)

x-value: -1

y=4/-1

y=-4

(-1, -4)

x-value: 0

y=4/0

y=0

(0, 0)

x-value: 1

y=4/1

y=4

(1, 4)

x-value: 2

y=4/2

y=2

(2, 2)

x-value: 4

y=4/4

y=1
