Footballs sell for $27.99 each at Dicks Sporting Goods and $21.59 each at Big 5. If the coach buys a dozen footballs, how much c

klasskru [66]

Answer:

The money he can save by buying them at Big 5 is $76.80.

Step-by-step explanation:

Given:

Footballs sell for $27.99 each at Sporting Goods.

Footballs sell for $21.59 each at Big 5.

The coach buys a dozen footballs.

Now, to find the amount he save by buying them at Big 5.

So, first we find the cost of footballs at Sporting Goods and at Big 5.

1 Dozen = 12 pieces.

Thus, the cost of footballs at Sporting Goods =

$\$27.99\times 12 =\$335.88$

And, the cost of footballs at Big 5 =

$\$21.59\times 12=\$259.08.$

Now, to get the amount coach can save by buying them at Big 5, we subtract both the cost as the cost of Sporting Goods is more than the Cost of Big 5:

The amount coach can save by buying them at Big 5 =

$\$335.88-\$259.08=\$76.80.$

Therefore, the amount he can save by buying them at Big 5 is $76.80.

Find the x-intercept of the function f(x) = a^x + 1 - 1.

babymother [125]

I am not certain of what you wrote for the function but will assume that is likely exponential function or quadratic function.

First, (quadratic function) To solve this, you must know the quadratic formula. The x-intercept is value(s) that has the output value(y) of 0.

If the vertex of the quadratic function of (0,0), there is only one x-intercept. The number and value of the x-intercept depends on the slope and vertical displacement.

Second, (exponential function) note that there is no x-intercept. For instance, if a is 2, is there such value y that 2^y is 0? The smallest exponential value that is an integer is 1. Even broadening the limit to rational numbers, no such exponential value can have the result of 0. Therefore, in the basic form of exponential function, there is no x-intercept.
