3. 7.74 + 9.281 =

Varvara68 [4.7K]

Answer:

All answers are in explanation

Step-by-step explanation:

7.74 + 9.281 = 13.055

8.2 x 4.3 = 35.26

32.5 x 6.88 = 223.6

37.4 ÷ 5.5 = 6.8

16.85 ÷ 5 = 3.37

35.75 + 55.50 x 2 = 146.75

The equation d=4-1/15t represents your distance from home, d, for each minute you walk, t. If you graphed this equation, determi

lara [203]

Answer: the slope is -1/15 and it means that the distance from home decreases 1/15 units per minute of walk, which indicates the your are going home.

Explanation:

The equation d = 4 - (1/5)t has these features:

it is a linear (first degree) equation/
d is the dependent variable, distance from home.
t is the independent variable, minutes of walk
4 is the constant term and it is the value of d when t = 0, which means that it is the vertical axis intercept and represents the initial distance from home.
- ( 1/15) is the coefficient of the independent variable, it is the slope of the equation, and means the rate of change of the distance per minute of walk.
this slope, since it is negative, means that the distance decreases as times goes on. It means that each minute of walk the distance decreases 1/15 unit.
you can find when the distance is zero, by doing the variable d = 0:

d = 0 = 4 - (1/15)t ⇒ t = 4×15 = 60 min.

The given equation, d = 4 - (1/5)t is a linear equation, whose y-intercept form is y = mx + b.

m is the slope, therefore it is - 1/15.
4 is the y-intercept, therefore it is 4.

The domain of the function is the interval [0, 60], meaning that those are the minutes of the walk.

The range of the function is the interval [4, 0] meaning that the distance goes from 4 to 0 units.

You have plenty information to do the graph:

label the horizontal axis t in minutes
do marks at 0, 5, 10, 15, 20, 25, .... up to 60 on the horizontal axis
lable the vertical axis d
do marks at 4, 3, 2, 1, on the vertical axis
draw the points (0, 4) and (60,0)
draw a segment joining those two points.

You can see the graph in the image attached.

A rectangle has a length of x and a width of 5x^3+4-x^2. What is the polynomial that models the perimeter of the rectangle

sveticcg [70]

Answer:

$L= x$

And the width for this case is:

$W= 5x^3 +4 -x^2$

And we know that the perimeter is given by:

$P= 2L +2W$

And replacing we got:

$P(x) = 2x +2(5x^3 +4 -x^2)= 2x +10x^3 +8 -2x^2$

And symplifying we got:

$P(x)= 10x^3 -2x^2 +2x+8$

Step-by-step explanation:

For this problem we know that the lenght of the rectangle is given by:

$L= x$

And the width for this case is:

$W= 5x^3 +4 -x^2$

And we know that the perimeter is given by:

Find the value of y. 4 5 7 2

Debora [2.8K]

Angles (7x+17)° and (5x-5)° are consecutive interior angles, that means they add up to 180°.
So we can make an equation to solve for x, which eventually will help us solve for y.
180 = (7x+17) + (5x -5)

re arrange that:
180 = 7x + 5x + 17 - 5

180 = 12x + 12
- 12 -12

168 = 12 x
 12 12

14 = x

Now we will plug it into (5x - 5) to help us solve for y,
Angle (5x - 5) and (23y) are supplementary angles, meaning they equal to 180°.
 180 = (23y) + (5(14) - 5)

180 = (23y) + (70 - 5)

180 = 23y + 65
- 65 - 65

115 = 23y
23 23

___ = y

Good luck!
