(x+3)^2+(y-1)^2=18
x and y always lie and you must square 9

The answer is 1 or A.

$(x-h)^{2}+ (y-k)^{2}= r^{2}$

$(x+3)^{2}+ (y-1)^{2}=81$

Answer:

Step-by-step explanation:

A triangles angles always sum up to 180 degrees. Since you already have 1 angle which is 43 degrees you will do 180-43 which is 137. The only angles that add up to 137 degrees is letter B.

Write an equation to represent Catherine's profit (p) from selling cupcakes for one month Catherine sells cupcakes, c, for 1.50

Archy [21]

Answer:

$\text{p}=\$1.20\text{c}-\$20$

Step-by-step explanation:

GIVEN: Catherine sells cupcakes c for $\$1.50$ each, The ingredients for each cupcake cost her $\$0.30$ , and the sum of all her other expenses is $\$20/\text{month}$ .

TO FIND: Equation to represent Catherine's profit from selling cupcakes.

SOLUTION:

Cost of ingredients for each cupcake $=\$0.30$

sum of all other expenses $=\$20/\text{month}$

Selling price of each cupcake $=\$1.50$

Total cupcakes sold $=\text{c}$

Now,

As we know that $\text{Net profit}=\text{Selling price}-\text{Cost price}-\text{Other expense}$

putting values,

$\text{p}=\$1.50\text{c}-\$0.30\text{c}-\$20$

$\text{p}=\$1.20\text{c}-\$20$

Hence the equation to represent Catherine's profit (p) from selling cupcakes for one month Catherine sells is $\text{p}=\$1.20\text{c}-\$20$

A diagonals of a parallelogram measures 37 inches. The size measures 35 inches and 1 foot. Is the parallelogram a rectangle?

Lostsunrise [7]

No, a parallelogram is not a rectangle. meaning it has a completely different area formula, I know it sucks.

Formula: base × height

I don't use feet and inches. sorry I couldn't provide with to much help.
