notka56 [123]

Answer:

Average speed is 48 km per hour

Step-by-step explanation:

A student drove to the university from her home and noted that the odometer reading of her car increased by 16.0 km. The trip took 20.0 min. (a) What was her average speed? in km/hr

Distance traveled is 16 km and the time taken is 20 minutes

convert minutes into hour. to convert minutes into hour we divide by 60 because 1 hour = 60 minutes

\frac{20}{60} =\frac{1}{3}

so time = 1/3  and distance = 16

Average speed = distance by time

speed =\frac{16}{\frac{1}{3} } =\frac{48}{1}= 48

Average speed is 48 km per hour

Slope intercept form that passes though the point (-2,-3) and has a slope of 5/2
olganol [36]

\text{Given that,}\\\\(x_1,y_1) = (-2,-3), ~~\text{and slope,}~~m = \dfrac 52\\\\\\\text{Now,}\\\\y -y_1 =m(x-x_1)\\\\\implies y +3 = \dfrac52 (x+2)\\\\\implies y = \dfrac 52(x+2) -3\\\\\\\implies y = \dfrac{5}2 x + 5 -3 \\\\\\\implies y = \dfrac 52 x + 2\\\\\\\text{This is the slope-intercept form(y =mx+b)}.

1. A group of workers is harvesting berries at a constant rate. An equation that represents the number of baskets of berries the
lbvjy [14]

Answer: (a) The slope of the line is 5 and the y-intercept is (0,10). (b) The rate of change is 5 and the initial amount is 10.

Explanation:

The given equation is,

y=5x+10     .... (1)

(a)

The slope intercept form of the a line is,

y=mx+b      .... (2)

Where, m is slope and (0,b) is y-intercept.

On comparing (1) and (2) we get,

m=5, b=10

Therefore, the slope is 5 and the y-intercept is (0,10).

(b)

The rate of change is also known as slope therefore the rate of change is 5.

To find the initial amount put x=0 in the given equation.

y=5(0)+10=10

Therefore, the initial value is 10.

The rate of change represents the number of baskets of berries the workers picked increased by 5 units per unit of time.

The initial amount shows the number of  baskets of berries the workers picked before the workers starts harvesting.

(c)The graph is shown below.

Since x represents the time in hours, therefore x is always greater that or equal to 0.
