No!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! NO NO NO NO NO... SEE BELOW!!!!!!

Step-by-step explanation:

LOL I like caps!!! and !'s

To question

If 5x3 is 5 $x^3$ then...

5x^3 times 2 equals 10x^3 no 10x^6

So the end result will be 10 $x^3\\$ + 9

you can see that there is 8 cm in middle of the trapezoid. above the trapezoid, it says 6 cm, below the trapezoid, it says 11 cm

aniked [119]

Answer:

The measure of the longer base is:

9 centimeters

Step-by-step explanation:

We know that the area of a trapezoid with height h and two parallel bases b and b' is given by the formula:

Here we have:

The area of a trapezoid is 30 square centimeters. The height is 4 centimeters. The shorter base measures 6 centimeters.

Given f(x)=3x+5 describe how the graph of g compares with the graph of f. g(x)=3(0.1)+5

mrs_skeptik [129]

The given function f(x) is:

$f(x)=3x+5$

And the other given function g(x) is:

$g(x)=3(0.1x)+5$

g(x) in comparison with f(x) has the next transformation:

1. g(x)=f(bx): g(x)=3(0.1x)+5. This is a horizontal stretch: the x-coordinates will change as:

$(x,y)\rightarrow(\frac{x}{0.1},y)$

This is the graph of both functions:

The red-one is f(x) and the blue-one is g(x).

Then for example when the coordinates of f(x) are (1,8) for g(x) the coordinates will be:

$(\frac{1}{0.01},8)=(10,8)$

Then, the slope of f(x) has a greater value than the slope of g(x), since the change on the x-axis is bigger in the g(x) graph for the.

Question 10 The hypotenuse of a right triangle is I m longer than the longer leg. The other leg is 7 m shorter than the longer l

bonufazy [111]

Answer:

5, 12, 13

Step-by-step explanation:

let x be the longer leg then x + 1 is the hypotenuse and x - 7 the shorter leg

Using Pythagoras' identity in the right triangle

x² + (x - 7)² = (x + 1)² ← expand using FOIL

x² + x² - 14x + 49 = x² + 2x + 1

2x² - 14x + 49 = x² + 2x + 1 ( subtract x² + 2x + 1 from both sides )

x² - 16x + 48 = 0 ← in standard form

(x - 4)(x - 12) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 4 = 0 ⇒ x = 4

x - 12 = 0 ⇒ x = 12

x = 4 , then x - 7 = 4 - 7 = - 3 ← not possible

x = 12, then x - 7 = 12 - 7 = 5 and x + 1 = 12 + 1 = 13

The lengths of the 3 sides are

longer leg = 12 m , shorter leg = 5 m and hypotenuse = 13 m

Please helppp!!!! I’ll give you a crown!!

Shkiper50 [21]

Answer:

I think the answer is 2

Step-by-step explanation:

I it is perpendicular to y=2x-3 then the x value has to be -1 meaning that the x value has to be -2x

so we have Y=-2x+c

We know the Y value is -3 from the co ordinates (0,-3)

so now we have -3=-2x+c

we also know x=0 from the co-ordinates (0,-3)

so we now have -3=-2*0+c

-3=0+c

to make the equation work c has to be -3 meaning that we now have

-3=0-3 which is

Y=-2x-3

A class trip to a beach has been planned for your senior trip. The resort only allows swimming when the temperature is between 7

Bad White [126]

Answer:

$\large\boxed{C.\ 75$

Step-by-step explanation:

x - the temperature

y - the number of people

the temperature is between 75 degrees and 110 degrees:

75 < x < 110

the room for 50 people:

0 < y ≤ 50
