Answer:

7.5 square miles

Step-by-step explanation:

Begin by counting the number of squares that the lake completely or almost completely covers. There are six of these, as indicated by an X. Then find the squares which are about half covered by the lake. These are indicated by a Y. There are three of these. The remainder of the squares that contain some portion of the lake are less than half covered, so we will not count them.

Irregular Object

1 square = 1 sq. mile

Each X counts as one square mile, and each Y counts as 0.5 (12) of a square mile.

(6 × 1) + (3 × 0.5) = 6 + 1.5 = 7.5

The area of the lake is about 7.5 square miles.

PLEASE HELP<br>L has y-intercept (0,5) and is perpendicular to the line with equation y=1/3x+1

marin [14]

Answer:

y=-3x+5

Explanation:

Given a line L such that:

• L has y-intercept (0,5); and

• L is perpendicular to the line with equation y=(1/3)x+1.

We want to find the equation of the line in the slope-intercept form.

The slope-intercept form of the equation of a straight line is given as:

$\begin{equation} y=mx+b\text{ where }\begin{cases}m={slope} \\ b={y-intercept}\end{cases} \end{equation}$

Comparing the given line with the form above:

$y=\frac{1}{3}x+1\implies Slope,m=\frac{1}{3}$

Next, we find the slope of the perpendicular line L.

• Two lines are perpendicular if the product of their slopes is -1.

Let the slope of L = m1.

Since L and y=(1/3)x+1 are perpendicular, therefore:

$\begin{gathered} m_1\times\frac{1}{3}=-1 \\ \implies Slope\text{ of line L}=-3 \end{gathered}$

The y-intercept of L is at (0,5), therefore:

$y-intercept,b=5$

Substitute the slope, m=-3, and y-intercept, b=5 into the slope-intercept form.

$\begin{gathered} y=mx+b \\ y=-3x+5 \end{gathered}$

The equation of line L is:

$y=-3x+5$

Brynn and Denise launch their rockets at the same time. The height of Brynn’s rocket, in meters, is given by the function f(x)=-

Vladimir [108]

Answer:

The height of rocket is 102.7 meter.

Step-by-step explanation:

Given : Brynn and Denise launch their rockets at the same time.

The height of Brynn’s rocket, in meters, is given by the function $f(x)=-4.9x^2+75x$ , where x is the number of seconds after the launch.

The height of Denise’s rocket, in meters, is given by the function

$g(x)=-4.9x^2+50x+38$ , where x is the number of seconds after the launch.

There is a moment when the rockets are at the same height.

To find : The height

Solution :

When the rockets have same height

So, $f(x)=g(x)$

$-4.9x^2+75x=-4.9x^2+50x+38$

$-4.9x^2+75x+4.9x^2-50x=38$

$25x=38$

$x=\frac{38}{25}$

$x=1.52$

Now, we put x value in any of the function to find height.

$f(x)=-4.9x^2+75x$ , x=1.52

$f(x)=-4.9(1.52)^2+75(1.52)$

$f(x)=-11.32096+114$

$f(x)=102.67$

Nearest tenth = 102.7

Therefore, The height of rocket is 102.7 meter.
