The original price of a jacket was 72.50$ Maria used a coupon for 20% off to buy the jacket. How much did she pay before tax?
Afina-wow [57]

Answer: Maria payed $58.00 for her jacket BEFORE tax.

Step-by-step explanation:

To find the answer to this question, we must first multiply 72.50 by 0.20. After doing so, we get 14.5 (this is the sale money). Finally, we subtract $72.50-14.5 to get out answer, 58 dollars.

Determine the quadratic function f whose graph is given. The vertex is (1,-3) and y-intercept is -2
Nesterboy [21]

Answer:

Vertex form: f(x)=(x-1)^2-3

Standard form: f(x)=x^2-2x-2

Step-by-step explanation:

A quadratic function in vertex form is f(x)=a(x-h)^2+k where (h,k) is the vertex.

We are given h=1,k=-3.

Let's plug that in:

f(x)=a(x-1)^2-3.

Now let's find a.

We will use the y-intercept (0,-2) to find a.

f(0)=a(0-1)^2-3

-2=a(0-1)^2-3

-2=a(-1)^2-3

-2=a(1)-3

-2=a-3

1=a

So the function in vertex form is:

f(x)=(x-1)^2-3.

In standard form, we will have to multiply and combine any like terms.

Let's do that:

f(x)=(x-1)(x-1)-3

f(x)=x^2-x-x+1-3

f(x)=x^2-2x-2

A metallurgist is designing an experiment to determine the effect of flux, base metal, and energy input on the hardness of a wel
Anastasy [175]

Answer: 24

Step-by-step explanation:

Given : A metallurgist wants to study four different fluxes, two different base metals, and three different amounts of energy input.

i.e. 4 different choices for fluxes.

2 different choices for base metals.

3 different choices for amounts of energy input.

If each run of the experiment involves a choice of one flux, one base metal, and one amount of energy input.

Then , the number of runs are possible :-

4\times2\times3=24

Hence, there are 24 different runs are possible .
