Draw a right triangle with one leg value is 4 and the other leg value is 3. Use the triangle to find the exact values of the six

Nina [5.8K]

Step-by-step explanation:

Draw a right triangle with one leg value is 4 and the other leg value is 3

The triangle is attached below

To find hypotenuse , use Pythagorean theorem

$c^{2} =a^{2} +b^{2} \\c^{2} =3^{2} +4^{2} \\\\c^{2} =25 \\\\c=\sqrt{25} =5$

opposite side = 4, adjacent side =3 and hypotenuse = 5

Apply trigonometric ratios

$sin(A)=\frac{opposite}{hypotenuse}=\frac{4}{5}$

$cos(A)=\frac{adjacent}{hypotenuse}=\frac{3}{5}$

$tan(A)=\frac{opposite}{adjacent}=\frac{4}{3}$

$cosec(A)=\frac{hypotenuse}{opposite}=\frac{5}{4}$

$sec(A)=\frac{hypotenuse}{adjacent}=\frac{5}{3}$

$cot(A)=\frac{adjacent}{opposite}=\frac{3}{4}$

Based on information in the table, which equation can be used to model the relationship between x and y?.

Ivahew [28]

The relationship between y and x is y = 5x + 15.

<h3>Linear equation</h3>

A linear equation is in the form:

y = mx + b

where y, x are the variables, m is the rate of change (slope) and b is the initial value of y (y intercept).

From the table, using point (5, 40) and (25, 140):

$y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-40=\frac{140-40}{25-5} (x-5)\\\\y=5x+15$

The relationship between y and x is y = 5x + 15.

Given s = 10 and h = 15. Find the total surface area of the square prism.

anastassius [24]

Answer:

150

Step-by-step explanation:

h = hight

s = sides

surface = 10 x 15

surface = 150

(V = 10 x 10 x 15

(V = 100 x 15)

(V = 1500)

(Base area = B)

(B = Lenght x Width)

(B = 10 x 10)

(B = 100)

i think of a number. if i divide the sum of 6 and the number by 3, the result is 4 more than one quarter of the number. find the

slega [8]

Answer:

-12

Step-by-step explanation:

Let the number be A

Given if you divide the sum of six and the number A by 3 , the result is 4 more than 1/4 of A

That’s

6+A/3 = 4+1/4 of A

6+A/3 = 4+1/4 x A

6+A/3 = 4+A/4

Cross multiply

4(6 + A) = 3(4 + A)

Distribute

4 x 6 + 4 x A = 3 x 4 + 3 x A

24 + 4A = 12 + 3A

Subtract 24 from both sides to eliminate 24 on the left side

24 - 24 + 4A = 12 - 24 + 3A

4A = -12 + 3A

Subtract 3A from both sides so the unknown can be on one side

4A - 3A = -12 + 3A - 3A

A = -12

Check

6+(-12)/3 = 4 +(-12)/4

6 -12/3 = 4 -12/4

-6/3 = -8/4

-2 = -2

kenny6666 [7]

Answer:

Workland has lower productivity but higher real GDP per person than Laborland.

Step-by-step explanation:

Consider the provided information.

Workland has a population of 10,000, of whom 7,000 work 8 hours a day to produce a total of 224,000 final goods.

Productivity = Output / Input

For Workland productivity is:

$\frac{224,000}{7,000 \times 8}=\frac{224,000}{56,000}= 4$

Laborland has a population of 5,000, of whom 3,000 work 7 hours a day to produce a total of 105,000 final goods.

For Laborland, productivity is:

$\frac{105,000 }{3,000\times 7}=\frac{105,000 }{21,000 }= 5$

Thus, Laborland has higher productivity .

To figure real GDP per person, divide output by population:

For Workland,

$\frac{224,000}{10,000}= 22.4$

for Laborland,

$\frac{105,000 }{5,000 }= 21$

Thus, Workland has a higher real GDP per person.
