3n - 7m for n = 5 amd m = 4

Answers

Answer 1

Answer:

-13

Step-by-step explanation:

first you will subsitute 5 for n in the  equation to get 3(5)-7m

next you will subsitute 4 for m in the equation to get 3(5)-7(4)

then solve: 3x5= 15

7x4= 28

15-28= -13

Answer 2
-13
3x5=15
7x4=28
15-28= -13

Find the coordinates of H if X(-8, 4) is the midpoint of GH and G(2, -9).

Answers

Step-by-step explanation:

Hey there!

The given midpoint is; X(-8,4) and G(2,-9).

To find: H

Now; You need to use formula for midpoint.

[tex]midpoint(x) = ( \frac{x1 + x2}{2} , \frac{y1 + y2}{2} )[/tex]

Put all values.

[tex]( - 8,4) = (\frac{ 2 + x}{2} , \frac{ - 9 + y}{2} )[/tex]

As they are equal, their corresponding elements are equal.

[tex] - 8 = \frac{2 + x}{2} [/tex]

[tex] - 16 - 2 = x[/tex]

x = -18

[tex]4 = \frac{ - 9 + y}{2} [/tex]

[tex]4 \times 2 = - 9 + y[/tex]

[tex]8 + 9 = y[/tex]

[tex]y = 17[/tex]

Therefore, y = 17.

Therefore, H =( -18,17).

Hope it helps....

Answer:

(-18, 17)

Step-by-step explanation:

Given Line segment GH with midpoint X(-8, 4) and G(2, -9)To findCoordinates of H(x, y)Solution

Using midpoint formula

(2 + x)/2 = -8 ⇒ x + 2 = -16 ⇒ x = -18(-9 + y)/2 = 4 ⇒ y - 9 = 8 ⇒ y = 17

So the coordinates of H are

(-18, 17)

Which type of discontinuity exists at x=0?​

Answers

Answer:

removable

Step-by-step explanation:

f(x) = cos(1/x^2) at x = 0;

For the function f(x) = cos(1/x^2) let's substitute the value of 0 in for x...

= cos(1/(0)^2)

= cos(1/0)

Now remember that x/0 is undefined. Removable discontinuity is undefined at the point x₀, and hence our solution is "removable."

Problem 2, Part (a)

A = event elevator's 1st stop at the 2nd floor

P(A) = 3/4

Since the elevator needs to go up one floor

B = event elevator has its 2nd stop at the 3rd floor

P(B given A) = probability event B happens given event A happened

P(B given A) = 3/4

-----------

P(A and B) = P(A)*P(B given A)

P(A and B) = (3/4)*(3/4)

P(A and B) = 9/16

Answer: 9/16

===============================================================

Problem 2, Part (b)

A = event elevator's 1st stop at the 2nd floor

P(A) = 3/4

B = event elevator has its 2nd stop at the 3rd floor

P(B given A) = 3/4

C = event elevator has its 3rd stop at 4th floor

P(C given (A and B)) = 3/4

-----------

P(A & B & C) = P(A)*P(B given A)*P(C given (A and B))

P(A & B & C) = (3/4)*(3/4)*(3/4)

P(A & B & C) = 27/64

Answer: 27/64

It takes 66 pounds of seed to completely plant a 7-acre field.
How many acres can be planted per pound of seed?
acres per pound

Answers

Answer:

Approximately 0.11 acres can be planted with one pound of seed

Step-by-step explanation:

You use the rule of 3

66 pounds / 7 acres = ? pounds / 1 acre

? = 66 x 1 ÷ 7

? = 66 ÷ 7

? ≈ 9.23 pounds / acre

Now you know how many pounds you have for 1 acre. You reuse the formula from before

9.23 pounds / 1 acre = 1 pound/ ? acres

? = 1x1 ÷ 9.23

? = 1 ÷ 9.23

? = 0.11 acres/pound

Verify the answer:

0.11 x 9.23 ≈ 9.33, which is approximately 1 pound

Answer:

90 pounds per acre

What is triangle?

A triangle is a polygon with three edges and three vertices. The sum of all the angles of a triangle is 180 degrees. Mathematically -

∠x + ∠y + ∠z = 180°

The sum of two sides of a triangle is greater then the third side. Mathematically -

a + b > c

There are different types of triangles such as -

equilateral triangle , scalene triangle , isosceles triangle etc.

Given is a triangle PQR and line segment AB, which is parallel to QR.

[A] -

ΔPQR is similar to ΔPAB as -

∠P = ∠P (Common)

∠PAB = ∠PQR (Corresponding angles)

∠PBA = ∠PRQ (Corresponding angles)

Using AAA similarity rule, ΔPQR is similar to ΔPAB.

[B] -

Line segment AB corresponds to line segment QR

[C] -

∠A in ΔPAB corresponds to ∠Q.

Therefore, the answers to all parts are given above.
