The graph shows the girth of the trunk of a fir tree after different numbers of years: What does the y-intercept of the graph re

Talja [164]

The y-intercept represents the initial girth of the tree. Assuming that the X-axis represents time in this scenario (as it usually does) the y-axis, therefore, represents the girth of the tree. The y-intercept is located where X = 0. So if no time has passed then this must be the first measurement of the girth of the tree.

A 14.5-m fire truck ladder is leaning against a wall. Find the distance d the ladder goes up the wall (above the fire truck)

UkoKoshka [18]

Answer:

h = 7.47 m

Step-by-step explanation:

According to the question, we have a right triangle formed by the ladder with the wall and the floor.

The length of the ladder is the hypotenuse and the desired height is the opposite. This is due to the fact that "the ladder makes an angle of 21" 27" with the horizontal". Then, the trigonometric ratio to use is sine:

$sin(\theta)=\frac{opposite}{hypotenuse}$

Using the values given:

$sin(\21"27")=\frac{h}{14.5}$

Multiplying both sides by 14.5:

$14.5*sin(\21"27")=14.5*\frac{h}{14.5}$

$14.5*sin(\21"27")=h$

Then h = 7.47 m

Leslie used 20% of a half-gallon (64 ounces) of milk for a recipe. How many ounces of milk were left?

Lady_Fox [76]

Answer:

51.2 ounces.

Step-by-step explanation:

If its 20% of a 64 ounce half gallon, you just need to find the last 80% of the half gallon. Since you know it is 64 ounces you can divide it by 5 which gives you 12.8. 12.8 would be 20% so you just subtract 12.8 from 64 ounces which gives you 51.2.

9. Write The eQuaTION OF THE LINE THAT Passes THROUGH THE

lara31 [8.8K]

The final equation of line that passes through (9, 0) AND (0, -6) is:

$y=\frac{2}{3}x-6$

Further explanation:

The general form of equation of line is:

$y=mx+b$

Given

(x1,y1) = (9,0)

(x2,y2) = (0, -6)

We have to find the slope first:

$m=\frac{y_2-y_1}{x_2-x_1}\\= \frac{-6-0}{0-9}\\=\frac{-6}{-9}\\=\frac{2}{3}$

Putting the value of slope in general form

$y=\frac{2}{3}x+b$

To find the value of b, we have to put a point in the equation

Putting (9,0) in equation

$0=\frac{2}{3}(9)+b\\0=2*3+b\\0=6+b\\b=-6$

Putting the values of b and m in general form

The final equation of line that passes through (9, 0) AND (0, -6) is:

$y=\frac{2}{3}x-6$
