A grocery store has received a shipment of apples.There are 15 boxes of apples,and each box contains 17 bags of apples. Each bag

gogolik [260]

Answer:

There are 3060 apples in the shipment.

Step-by-step explanation:

Given:

Number of boxes of apples = 15

Each boxes contains = 17 bags of Apples

hence 15 boxes will contains = Number of bags of apples in 15 boxes.

By Using Unitary Method we get;

Number of bags of apples in 15 boxes = $15\times 17= 255 \ bags \ of \ apples$

Hence 15 boxes contains = 255 bags of apples.

Also Given:

Each bag contains = 12 apples

255 bags contains = Number of apples in 255 bags

By Using Unitary Method we get;

Number of apples in 255 bags = $255\times12= 3060 \ apples$

Hence 255 bags of apples contains = 3060 apples.

Hence There are 3060 apples in the shipment.

The function y=−16x2+36 represents the height y (in feet) of an apple x seconds after falling from a tree. Find and interpret th

Lapatulllka [165]

Answer:

A. x-intercept=x=1.5 , y-intercept=y=36

B.the apple will hit the ground after x=1.5 seconds.

Step-by-step explanation:

A. X-intercept and Y-intercept:

X-intercept:

the point where the line passes through X-axis i.e. point where y=0

Y-intercept:

the point where the line passes through Y-axis i.e. point where x=0

Given Equation:

$y=-16x^2+36$

Finding X-intercept:

to find x-intercept, put y=0 in the given equation as

$0=-16x^2+36\\$

adding $-16x^2$ to both sides of the equation, we get

$16x^2=36$

dividing both sides by 16, we get

$x^2=\frac{36}{16}\\x^2=2.25$

taking√ on both sides of the equation, we get

$x=\sqrt{2.25}\\ x=1.5$

Finding Y-intercept:

to find y-intercept, put x=0 in the given equation

$y=-16(0)^2+36\\y=36$

thus x-intercept $=x=1.5$

and y-intercept $=y=36$

B.when will the apple hit the ground after x seconds?

In the given equation if x represent the time in seconds then y represents the height of the tree from which the apple is fallen down

so if the apple hits the ground, at this stage the height is zero so y=0, thus we get x as

$0=-16x^2+36\\$

dividing both sides by 16, we get

$x^2=\frac{36}{16}\\x^2=2.25$

taking√ on both sides of the equation, we get

$x=\sqrt{2.25}\\ x=1.5$

the apple will hit the ground after x=1.5 seconds.

The graph represents function 1 and the equation represents function 2:

Mazyrski [523]

Answer:

Step-by-step explanation:

subtract both slopes

in word problems:

"rate of change" means slope

1. horizontal line's slope is 0

2. number next to the x is the slope

y = 4x + 1 : slope is 4

3. "How much more" is word problems means subtract

4 - 0 = 4

horizontal and vertical lines' slopes are 0
