ella [17]

That would be-
f(t)=80t+4
How I worked that out-
f(x)=mx+b
b= the y intercept which is 4
mx= your slope, which is 80t
f(t) is your height

A contractor can pay his crew at most $250 a day. It costs $45 each day to operate the forklift and $60 a day for each crew memb

zzz [600]

The answer is B. His budget is $250 so it has to be less than or equal to. $60 a crew member (x = the crew members) and $45 to use the forklift, so $60x + $45 is less than or equal to $250

Find the gradient of the line Joining the points p(-2,6) and Q(3,-2)

Rudiy27

Answer:

$- \frac{8}{5}$

Step-by-step explanation:

$\boxed{gradient = \frac{y1 - y2}{x1 - x2} }$

(x₁, y₁) is the 1st coordinate while (x₂, y₂) is the 2nd coordinate.

Gradient of the line

$= \frac{6 - ( - 2)}{ - 2 - 3}$

$= \frac{6 + 2}{ - 5}$

$= - \frac{8}{5}$

What is the measurement of angle∠ADC?<br> 131<br> 121<br> 42<br> 47

Jet001 [13]

Answer: First option.

Step-by-step explanation:

For this exercise it is important to observe the picture given in the exercise and analize the information provided.

You can observe in the picture that the measure of the angle ADC can be obtained my adding the measures of the angles ADB and BDC. Therefore, knowing this, you can write the following equation:

$m\angle ADC=m\angle ADB+m\angle BDC$

You can identify in the picture that:

$m\angle ADB=89\°\\\\m\angle BDC=42\°$

Therefore, you can substitute those values into the equation and then evaluate in order to find the measure of the angle ADC.

You get that this is:

$m\angle ADC=89\°+42\°\\\\m\angle ADC=131\°$
