Answer:

See explanation

Step-by-step explanation:

Car A: Started at 0 and ended at 300, thus, car A travels 300 miles.

It travels 6 hours, so car A speed is $\frac{300}{6}=50$ mph.

Car B: Started at 100 and ended at 300, thus, car B travels 300-100=200 miles.

It travels 5 hours, so car B speed is $\frac{200}{5}=40$ mph.

Since 50>40, car A traveled faster than car B.

The graph for the car A is steeper than the graph for the car B.

Martin wants to build an additional closet in a corner of his bedroom. Because the closet will be in a corner, only two new wall

Gekata [30.6K]

The relationship between the length & the width of the closet and the length of the wall is an illustration of a linear equation.

The equation for f(l) is: $f(l) = 1.5l$ .
The desired length and width are 8m and 4m

Given that:

$l = 2w$

Divide both sides by 2

$w = 0.5l$

Equation of f(l)

The sum of the length and the width is represented as: f(l).

So, we have:

$f(l) = l + w$

Substitute $w = 0.5l$

$f(l) = l + 0.5l$

$f(l) = 1.5l$

See attachment for the graph of f(l)

The desired dimension

From the question, we understand that the total length is 12m.

This means that:

$f(l) = 12$

So, we have:

$1.5l = 12$

Divide both sides by 1.5

$l = 8$

Recall that:

$w = 0.5l$

$w = 0.5 \times 8$

$w = 4$

Hence, the desired length and width are 8m and 4m, respectively.

Changle. Show all work. Round each length to the nearest tenth and each angle to the

Sedaia [141]

Answer:

Part 1) $BC=12.2\ units$

Part 2) $m\angle A=55^o$

Part 3) $m\angle C=35^o$

Step-by-step explanation:

Part 1) Find AC

we know that

In the right triangle ABC of the figure

Applying the Pythagorean Theorem

$AC^2=AB^2+BC^2$

substitute the given values

$AC^2=7^2+10^2$

$AC^2=149\\AC=12.2\ units$

Part 2) Find the measure of angle A

we know that

In the right triangle ABC

$tan(A)=\frac{BC}{AB}$ ----> by TOA (opposite side divided by the adjacent side)

substitute the values

$tan(A)=\frac{10}{7}$

using a calculator

$m\angle A=tan^{-1}(\frac{10}{7})=55^o$

Part 3) Find the measure of angle C

we know that

In the right triangle ABC

$m\angle A+m\angle C=90^o$ ----> by complementary angles

substitute the given value

$55^o+m\angle C=90^o$

$m\angle C=90^o-55^o=35^o$
