Answer:

C. Scalene

Step-by-step explanation:

Scalene triangles have three different side lengths. This triangle has three different side lengths from the points given so it must be scalene.

Equilateral would be three identical side lengths.

Isosceles would have two identical side lengths.

Answer:

1. the range is the biggest number minus the smallest number.

2. for IQR order the data in ascending order, find the median, calculate the median for both the upper and lower halves of the data and the IQR is the difference between the two.

3. MAD is when you find the mean then add all the data values together and divide by the amount of data you have. Lastly, do the data value minus the mean.

harina [27]

Answer:

If gabe has a gift card for $50 then it will cover the cost of jeans.

Step-by-step explanation:

Given:

Gabe is buying a pair of jeans at a local store that are priced at $45.

He knows that the country he lives in has an 8% tax added onto the list price.

Now, if gabe has a gift card for $50 to get will it cover the cost of jeans.

Price of a pair of jeans = $45.

Tax = 8%.

Now, getting the amount of jeans including tax:

$45 + 8% of $45.

= $45+\frac{8}{100} \times 45$

$=45+0.08\times 45$

$=45+3.6$

$=48.6$

Thus, the amount of jeans including tax = $48.60.

As, given Gabe has gift card of $50.

Now, subtracting the amount of jeans from amount of gift card:

$50-48.60=1.40$

So, $1.40 is still remaining.

Therefore, if gabe has a gift card for $50 then it will cover the cost of jeans.

Graph f(x) =-2x^+16x-30 by factoring to find the solutions, then find the coordinates of the vertex, and the axis of symmetry. I

fredd [130]

Answer:

Observe attached image

Function zeros:

(3, 0), (5, 0)

Vertex:

(4, 2)

Axis of symmetry:

 $x =4$ 

Step-by-step explanation:

First factorize the function

$f (x) = -2x ^ 2 + 16x-30$

Take -2 as a common factor.

$-2(x ^ 2 -8x +15)$

Now factor the expression $x ^ 2 -8x +15$

You must find two numbers that when you add them, obtain the result -8 and multiplying those numbers results in 15.

These numbers are -5 and -3

Then we can factor the expression in the following way:

$f (x) = -2(x-5)(x-3)$

The quadratic function cuts the x-axis at x = 3 and at x = 5.

Now we find the coordinates of the vertex.

For a function of the form $ax ^ 2 + bx + c$ the x coordinate of its vertex is:

$x = \frac{-b}{2a}$

In the function $f (x) = -2x ^ 2 + 16x-30$

$a = -2\\b = 16\\c = 30$

Then the vertice is:

$x = \frac{-16}{2(-2)}\\\\x = 4$

The y coordinate of the symmetry axis is

$y = f (4) = -2 (4) ^ 2 +16 (4) -30\\\\y = 2$

The axis of symmetry is a vertical line that cuts the parabola in two equal halves. This axis of symmetry always passes through the vertex.

Then the axis of symmetry is the line

$x = 4$

The solutions and the vertice written as ordered pairs are:

Function zeros:

(3, 0), (5, 0)

Vertex:

(4, 2)
