Answer and Step-by-step explanation:

For this triangle, to find x, we will use the cosine trigonometric function.

cosine functions look like this:

$cos(\theta) = \frac{adjacent}{hypotenuse}$

(The weird looking symbol is called theta, and represents an angle measurement)

Plug in the values into the equation.

cos(42) = $\frac{x}{15}$

Multiply both sides by 15.

15(cos(42)) = x

Plug into a calculator.

11.1472 is the answer.

Using the graph below, find the point(s) such that the sum of their coordinates is equal to 7.

gregori [183]

Answer:

Only A, B and C are the points whose coordinates are equal to 7.

Step-by-step explanation:

Considering the point A

As the location of point A is (0, 7)

The sum of their coordinates is equal to 0 + 7 = 7

Considering the point B

As the location of point B is (2, 5)

The sum of their coordinates is equal to 2 + 5 = 7

Considering the point C

As the location of point C is (6, 1)

The sum of their coordinates is equal to 6 + 1 = 7

Considering the point D

As the location of point D is (4, -3)

The sum of their coordinates is equal to 4 + ( -3 ) = 1

Considering the point E

As the location of point E is (1, -6)

The sum of their coordinates is equal to 1 + ( -6 ) = -5

Considering the point F

As the location of point F is (-2, -4)

The sum of their coordinates is equal to -2 + ( -4 ) = -2 - 4 = -6

Considering the point G

As the location of point F is (-5, -2)

The sum of their coordinates is equal to -5 + ( -2 ) = -5 - 2 = -7

Considering the point H

As the location of point H is (-4, 3)

The sum of their coordinates is equal to -4 + ( 3 ) = -4 + 3 = -1

From the above discussion, only A, B and C are the points whose coordinates are equal to 7.

Differential cos^2x dy/dx =e^y-tanx

gulaghasi [49]

Answer:

y=t−1+ce

−t

where t=tanx.

Given, cos

+y=tanx

⇒

+ysec

x=tanxsec

x ....(1)

Here P=sec

x⇒∫PdP=∫sec

xdx=tanx

∴I.F.=e

tanx

Multiplying (1) by I.F. we get

tanx

ysec

x=e

tanx

tanxsec

Integrating both sides, we get

tanx

=∫e

tanx

.tanxsec

xdx

Put tanx=t⇒sec

xdx=dt

∴ye

=∫te

dt=e

(t−1)+c

⇒y=t−1+ce

−t

where t=tanx

Y=6x/5 +27 find y-intercept and slope

mixas84 [53]

Answer:

General equation of a line is given by y = mx +c, where m is the gradient /slope, c is the intercept. To find for the intercept on y- axis, put x = 0.
$y = \frac{6(0)}{5 } + 27 \\ y = \frac{0}{5} + 27 \\ y = 27 \\ therefore \: the \: intercept \: on \: y \: is \: 27 \\$
By comparison,
$y = mx + \: c \\ y = \frac{6}{5} x \: +27 \\ m = \frac{6}{5 \: } \: \\ hence \: slope \: is \: \frac{6}{5}$

A rectangular plot measures 20 ft. By 30ft. A 3ft wide side walk surrounds it. Find the area of the side walk

r-ruslan [8.4K]

Answer:

336 feet²

Step-by-step explanation:

If we have a rectangle that is 30 by 20 feet, that means the area of that rectangle would be 20 × 30 feet squared, which is 600 ft².

If there is a 3 feet sidewalk surrounding it, that means that the end of the sidewalk will extend 3 feet extra around each side of plot. Since there are two ends to one side, that means an extra six feet is added on to each dimension. Therefore, 36 × 26 are the dimensions of the sidewalk+plot. 36 × 26 = 936 ft².

To find the area of the sidewalk itself, we subtract 600 ft² from 936 ft². This gets us with 336 ft².

Hope this helped!
