Answer:

D

Step-by-step explanation:

By looking at this scatter plot we can see that the points generally go down when looking at the graph from left to right.

This somewhat straight line that is created is going in a negative direction.

That means that it is not only a linear finction, but is also negative.

Answer:

58 ft

Step-by-step explanation:

So I attached a diagram that illustrates the triangle that is formed. We know an angle, as well as the hypotenuse. We are looking for the height, or in other words the opposite side of the angle. There is a trigonometric function defined as: $sin(\theta) = \frac{opposite}{hypotenuse}$ . Using this we can plug in known values and solve for the opposite side, which I'll simply represent as x.

$sin(46) = \frac{x}{80}$

Multiply both sides by 80

$sin(46) * 80 = x$

Calculate sin(46) using a calculator (make sure it's in degree mode)

$0.7193398 * 80 = x$

Simplify

$57.547 \approx x$

Round this to the nearest foot

$58 \approx x$

The difference between a number x and 3 is at least nine Write an inequality for the following sentence.

dybincka [34]

Answer:

3 - x ≥ 9

Step-by-step explanation:

At least in inequality means greater than or equal to (≥)

Difference in mathematics means subtraction

The difference between a number x and 3

3 - x

is at least nine

3 - x ≥ 9

The inequality for the sentence is

3 - x ≥ 9

Truck that delivers essentials in remote areas can travel 85 kilometers. Which

Mashcka [7]

Answer:

v = 85/t

Step-by-step explanation:

Velocity is the change in displacement of a body with respect to time. It is expressed as

velocity = displacement/time

v = d/t

Given

d = 85km

t = t

Substitute tis parameters into the function;

v = 85/t

Hence the velocity v as a function of travel time t in hours is expressed as;

v = 85/t

the function y=-2(x-3)^2+4 shows the daily profit (in hundreds of dollars) of a hot dog stand wherex is the price of a hot dog (

Pavlova-9 [17]

Step-by-step explanation:

$y=-2(x-3)^2+4$

To interpret the zeros of this function , put y =0

$0=-2(x-3)^2+4$

$0+2(x-3)^2=4$

$2(x-3)^2=4$

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

$(x-3)^2=2$

Taking square root on both sides:

$(x-3)=\pm \sqrt{2}$

So, we got values of x :

1) $x=3+\sqrt{2}=1.59$

2) $x=3-\sqrt{2}=4.41$

This means the person will have profit if price of a hot dog ranges from $1.59 to $4.41.
