I must run 15 miles per week what will be the inequality

1 answer:

7 0

If x is the amount of miles you run per week, then you will need to run more than 15 miles per week. So your inequality would be

The slope of AB is 3 over 4 and point A is (2. 9). How many possible locations are there for point

nignag [31]

Answer:

Part 1) There are infinity locations for the point B

Part 2) see the explanation

Step-by-step explanation:

Part 1) How many possible locations are there for point B?

we know that

The equation of a line in point slope form is equal to

$y-y1=m(x-x1)$

where

$m=\frac{3}{4}$

$(x1,y1)=(2,9)$

substitute

$y-9=\frac{3}{4}(x-2)$

Convert to slope intercept form

$y-9=\frac{3}{4}x-\frac{6}{4}$

$y=\frac{3}{4}x-\frac{6}{4}+9$

$y=\frac{3}{4}x+\frac{30}{4}$

$y=0.75x+7.5$

Point B can be any point ( different from point A) that satisfies the linear equation

therefore

There are infinity locations for the point B

Part 2) Describes a method to location the point

To locate the point, one of the two coordinates must be known. The known coordinate is placed into the linear equation and the equation is solved to find the value of the missing coordinate

Example

Suppose that the x-coordinate of point B is 4

For x=4

substitute in the linear equation

$y=0.75(4)+7.5=10.5$

The coordinates of point B is (4,10.5)

A lawn sprinkler sprays water 4 feet in all direction as it rotates.

Ber [7]

Answer:

50.24 ft^2

Step-by-step explanation:

The radius of the circle in which the lawn sprinkler sprays water is 4 feet.

The formula to find the area of a circle is $\pi r^2$ , where r = radius and π, in this case, is 3.14.

3.14 × 4^2
3.14 × 16
50.24 ft^2

Therefore, the answer is 50.24 ft².

Plz help me!!<br><br> Step by step to understand the answer plz

Doss [256]

Answer:

2/3

Step-by-step explanation:

so the inverse takes us from the range to the domain... they tell us that f(4) goes to 5.. so if we were to take the inverse f $\left \[-1} \atop$ (5) it takes us back to 4... and the slope at 4 or the derivative was 2/3 so that's what we get for f $\left \ {{-1} \atop$ '(5) :)
