what’s the slope of (9,3) and (2,11)

Answers

Answer:

slope = - [tex]\frac{8}{7}[/tex]

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (9, 3) and (x₂, y₂ ) = (2, 11)

m = [tex]\frac{11-3}{2-9}[/tex] = [tex]\frac{8}{-7}[/tex] = - [tex]\frac{8}{7}[/tex]

Answer:

[tex]\boxed {m = -\frac{8}{7}}[/tex]

Step-by-step explanation:

Use the Slope Formula to help you determine the slope of two given points:

[tex]m =\frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex]

First point: [tex](x_{1}, y_{1})[/tex]

Second point: [tex](x_{2}, y_{2})[/tex]

-Apply the two given points onto the formula:

First point: [tex](9, 3)[/tex]

Second point: [tex](2, 11)[/tex]

[tex]m =\frac{11 - 3}{2 - 9}[/tex]

-Solve for the slope:

[tex]m =\frac{11 - 3}{2 - 9}[/tex]

[tex]m =\frac{8}{-7}[/tex]

[tex]\boxed {m = -\frac{8}{7}}[/tex]

Therefore, the slope is [tex]-\frac{8}{7}[/tex].

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.

Answers

Answer:

Step-by-step explanation:

The measure of ∠A will be 50°.

What is mean by Triangle?

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

Δ ABC ≅ Δ DEF

And, m ∠A = (x + 30)°, m ∠C = 45°, and m ∠D = 80°

Now,

Since, Δ ABC ≅ Δ DEF

Hence, m ∠A = m ∠D

Substitute all the values, we get;

m ∠A = m ∠D

x + 30 = 80

Subtract 30 both side, we get;

x = 80 - 30

x = 50°

Thus, The measure of ∠A will be 50°.

What is the width plz help needed quickly brainiest will be given to whoever answers correctly

Answers

Answer:

2/3

Step-by-step explanation

The length of the park has been cut off in the question but if it is one mile, like I think it is, then this is the answer.

A = 2/3

A = L x W

2/3 = 1 X ?

? = 2/3

Answer:

width = 2/3 mile

Step-by-step explanation:

area = L * W

where area = 2/3 mile²

length = 1 mile

width = ?

2/3 = 1 (W)

2 = 3W

W = 2/3 mile

therefore the width = 2/3 mile

length = 1 mile

I took the test!!!

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

Step-by-step explanation:

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.
