Answer:

42 square units

Step-by-step explanation:

Hello There!

The area of a trapezoid can be found using this formula

$a = \frac{a + b}{2} h$

where a and b are bases and h is height

if you look at the graph we can see that the lines are counting by 2 units

knowing this we want to find the dimensions

the shown trapezoid has the following dimensions

a =2*2 or 4

b=5*2 or 10

h=3*2 or 6

having found this information we then plug it into the formula

$a = \frac{4+ 10}{2} 6 \\ 4 + 10 = 14 \\ \frac{14}{2} = 7 \\ 7 \times 6 = 42$

so we can conclude that the area of the trapezoid is 42 square units

Solve the question below 77

Answer:

<em>The height of the monument is 124.8 ft</em>

Step-by-step explanation:

<u>Right Triangles</u>

The ratios of the sides of a right triangle are called trigonometric ratios. The tangent ratio is defined as:

$\displaystyle \tan\theta=\frac{\text{opposite leg}}{\text{adjacent leg}}$

The figure attached below shows the different distances involved in the problem. We heed to find the value of h, the height from Daniel's eyes. Then we'll add it to the 6 ft where his eyes are located from the ground.

Taking the angle of 68° as a reference:

$\displaystyle \tan 68^\circ=\frac{h}{48}$

Solving for h:

$\displaystyle h=48\tan 68^\circ$

Calculating:

h = 118.8 ft

The height of the monument is 118.8 ft + 6 ft = 124.8 ft

Find the angle x in this triangle

Romashka-Z-Leto [24]

Answer:

x = 36

Step-by-step explanation:

<em>A triangle has 180°</em>.

That <em>third angle is 360 - 8x</em>.

So the equation is: <em>180 = 2x + x + 360 - 8x</em>.

Simplify: 180 = -5x + 360

Add/Subtract: 5x = 180

Divide: x = 36.

The given two-parameter family is a solution of the indicated differential equation on the interval

mr_godi [17]

Answer:

I do 1 option for you as an example, you need to check the leftover by yourself.

Step-by-step explanation:

for d) y(0) = 0 and y'(pi) =0

$y(0) = C_1e^0cos(0)+ C_2 e^0 sin(0) = 0 \longrightarrow C_1 = 0$

$y(x) ' = C_1e^x cos(x) - C_1e^x sin (x) + C_2e^x sin(x) + C_2e^x cos(x)$

$y(\pi)'=C_1e^\pi cos(\pi)- C_1e^\pi sin(\pi)+ C_2e^\pi sin(\pi) + C_2e^\pi cos (\pi)$

Replace $C_1 = 0$ we have

$y'(\pi) = -C_2e^\pi = 0$

if and only if $C_2 =0$

Hence the given solution does not work.

then, d is NOT the correct answer.

The dogs in an animal parade are grouped by size. There are 18 small dogs, 12 medium-sized dogs, and 10 large dogs. If one dog i

ruslelena [56]

Answer:

0.3

Step-by-step explanation:

Given:

Number of small dogs = 18

Number of medium-sized dogs = 12

Number of large dogs = 10

To find: probability that a medium-sized dog will be chosen

Solution:

Probability refers to chances of occurrence of some event.

Probability = number of favourable outcomes/total number of outcomes

Total number of dogs = 18 + 12 + 10 = 40

Number of medium-sized dogs = 12

So,

probability that a medium-sized dog will be chosen = Number of medium-sized dogs/Total number of dogs = $\frac{12}{40}=0.3$
