What is Pythagorean theorem?

Pythagorean theorem, the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)—or, in familiar algebraic notation, a2 + b2 = c2.

Here, given that,

she leaves the health club and bikes 16 miles south.

Then, She then runs 12 miles west.

so, we have,

It must be, hypotenuse = 16 miles

                  base= 12 miles

We have to find, the height.

by Pythagorean theorem, we get,

the distance Jane's trainer bikes=√16²-12² miles

                                                       =√32 miles

                                                       =5.66 miles

So. she travels in total = 28 miles

22.34 miles much farther does Jane travel than her trainer.

In 1992, Disney created a one-of-a-kind special pin. Each year, the pin’s value appreciates by a constant amount. In 1997, the pin was valued at $350. In 2002, it was valued at $600. Let x be the number of years since 1992 and y be the value of the pin in dollars. Write a linear equation in slope-intercept form that models this situation.

Answers

Answer:

[tex]y = 50x + 50[/tex]

Step-by-step explanation:

Given

x = years since 1992.

y = value of pin

This means that

[tex]x = 1[/tex] ----- in 1992

[tex]x_1 = 6[/tex]; [tex]y_1 = 350[/tex] ---- in 1997

[tex]x_2 = 11;[/tex] [tex]y_2 = 600[/tex] ---- in 2002

Required

Determine the line equation in slope intercept form

First, we need to determine the slope (m) of the line

[tex]m = \frac{y_2 - y_1}{x_2- x_1}[/tex]

[tex]m = \frac{600 - 350}{11- 6}[/tex]

[tex]m = \frac{250}{5}[/tex]

[tex]m = 50[/tex]

The equation is then calculated using:

[tex]y - y_1 = m(x - x_1)[/tex]

Recall that

[tex]x_1 = 6[/tex]; [tex]y_1 = 350[/tex]

[tex]m = 50[/tex]

So, we have:

[tex]y - 350 = 50(x - 6)[/tex]

[tex]y - 350 = 50x - 300[/tex]

[tex]y = 50x - 300 + 350[/tex]

[tex]y = 50x + 50[/tex]

Answer:

Answer Down Below

Step-by-step explanation:

Q's Asked: Which of the following options is an equivalent function to f(x) = 4(3)2x?

Possible answers:

f(x) = 36^x

f(x) = 4(9)^x

f(x) = 144^x

f(x) = 4(6x)

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

My answer: I Think the correct answer is (B) .

The reason why I think the answer is (b) is bc:

[tex]f(x) = 4(3)^{2x}[/tex] =36

Calculations on How I got 36.

Frist we calculate the exponents [tex]\left(3\right)^2[/tex] --> [tex]\left(3\right)^2=9[/tex]--->  =9

then we Multiply 4*9 which gives us : 36.

The reason why Its (B) is bc:

f(x) = 4(9)^x

which means 4 times nine is...... 36. thats the answer (B) f(x) = 4(9)^x

A farmer grows a particular plant that has a gene that can be manipulated to control the age t at which the plant matures. The number of seeds S(t) produced by a plant maturing at age t is S(t)=−0.3t2+30t+0.2 seeds per mature plant A farmer asks the geneticists to genetically engineer a plant line that accounts for the fact that on his farm, only P(t)=90000t+100, plants mature to age t. What age of maturity should the geneticist select for the plants to maximize the seed production of the farmer's crop?a. Between 130 and 140 days b. Between 120 and 130 days

Answers

Answer:

The correct option is;

Between 40 and 50 days

Step-by-step explanation:

The number of seeds that are produced by a plant maturing at age t, S(t), is given as follows;

S(t) = -0.3·t² + 30·t + 0.2

The proportion of plants maturing at age (t) in the plants to be engineered by the geneticist P(t) = 90000/(t + 100)

The number of seeds produced by the plants  = S(t) × P(t) = (-0.3·t² + 30·t + 0.2)×(90000/(t + 100))

To find the maximum number of seeds, we differentiate using an online tool, and equate to zero to get;

d((-0.3·t² + 30·t + 0.2)×(90000/(t + 100)))/dt = (-27000·t² - 5400000·t + 269982000)/(t + 100)² = 0

(-27000·t² - 5400000·t + 269982000)/(t + 100)² = 27000(t - 41.419)(t + 241.419)/(t + 100)² = 0

t = 41.419 or t = -241.419

Therefore, in order to maximize the production of seed of the crops of the farmer, the geneticist should select between 40 and 50 days.

The formula for the area of a triangle is A =12bh, in which b represents the length of the base and h represents the height. If a triangle has an area of 232 mm 2 and the height is 16 mm, what is the measure of the base? The measure of the base is mm.

Answers

Answer:

Step-by-step explanation:

Write it out: A = 1/2(bh)

substitute values: 232 = 1/2(16b)

Simplify: 232 = 8b

Divide each side by 8: b = 29

The base is 29 millimeters

2/3 = 1 X ?

? = 2/3

area = L * W

where area = 2/3 mile²

       length  = 1 mile

2/3 = 1 (W)

2 = 3W

W = 2/3 mile

m<QRS=48°

m<RSQ=69°

m<RQS=63°

Step-by-step explanation:

Since we know that the measures of the angles of any triangle is 180°, we can form this equation: 7a-1+10a-1+9a=180°

Then, we can use simple algebra to solve for a and plug in that value into the equations that the degrees represent to get our angle measures.

7a-1+10a-1+9a=180°

26a-2=180°

26a=182°

a=7

Now, plug in that value of a and you have your anlage measures!! Hope this helps!! :)
