450 is the correct answer
Marina86 [1]4 years ago
7 0

Answer:

450

Step-by-step explanation:

360 × 1.25 = 450

multiply by 1.25 because .25 is 25% and the 1 before it is to make sure you are finding the number plus the 25%, not just 25 percent of the number.

Please answer this question I need it i. Vertex and standard form.
Brums [2.3K]

Equation :

This parabola is facing downwards and highest point of the parabola is it's vertex.

Highest point is (-2,2)

so the vertex is (-2,2)

The graph is passing through (-1,0)

Equation in vertex form is

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

0 = a( - 1 + 2) {}^{2}  + 2 \\ 0 =a (1) {}^{2}  +2 \\  0 = a + 2 \\ a =  - 2

Substitute back in Equation

y =  - 2(x  + 2) {}^{2}  + 2

the graph has two x intercepts -1 and -3

that means (x+1) and (x+3) are the factors

multiply factors to get the equation in standard form

-2(x + 1)(x + 3) = 0 \\ -2(x {}^{2}  + x + 3x + 3) = 0 \\  -2( x {}^{2}  + 4x + 3) = 0

-2x^2-8x-6=0

Person A can make a cupcake in 5 minutes, Person B can make a cupcake in 9 minutes. In total they made 168 cupcakes. How many cu
Stolb23 [73]

Answer:

Person A made 108 cupcakes and person B made 60 cupcakes.

Step-by-step explanation:

Person A makes 1 cupcake in 5 minutes.

Say in x minutes A makes : \frac{x}{5} cupcakes

Person B makes 1 cupcake in 9 minutes.

Say in x minutes B makes : \frac{x}{9} cupcakes

Total cupcakes prepared by A and B in x minutes = 168

\frac{x}{5}+\frac{x}{9}=168

\frac{14x}{45}=168

x=\frac{168\times 45}{14}=540

So, cupcakes made by A = \frac{540}{5}=108

Cupcakes made by B = \frac{540}{9}=60

Person A made 108 cupcakes and person B made 60 cupcakes.
