Answer:

(- 2, 1 ) and (1, 4 )

Step-by-step explanation:

Given the 2 equations

y = - x² + 5 → (1)

- x + y = 3 → (2)

Rearrange (2) expressing y in terms of x by adding x to both sides

y = x + 3 → (3)

Substitute y = x + 3 into (1)

x + 3 = - x² + 5 ( subtract - x² + 5 from both sides )

x² + x - 2 = 0 ← in standard form

(x + 2)(x - 1) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 2 = 0 ⇒ x = - 2

x - 1 = 0 ⇒ x = 1

Substitute these values into (3) for corresponding values of y

x = - 2 : y = - 2 + 3 = 1 ⇒ (- 2, 1 )

x = 1 : y = 1 + 3 = 4 ⇒ (1, 4 )

Mica stands 75 feet away from the base of a tree and looks up towards the top of the tree at a 51 degree angle.

Answers

Answer:

Height of the tree =  92.61 feet

Step-by-step explanation:

Given: Distance between base of tree and Mica = 75 feet

Angle of elevation to the top of tree = 51°

Assuming we have to find the height of the tree = H

This can be found by applying simple trigonometry.

The height of the tree becomes perpendicular and distance between base of tree and Mica is base.

Then,  tan51° = H/75

⇒ H = 75× tan51° = 92.61 feet

A gaming
console costs
$300 and has
8% tax. How
much is the tax?

$30 or $24?

Answers

Answer:

24

Step-by-step explanation:

8 percent of 300 is 24.

that should be right

Answer:

$24

Step-by-step explanation:

The tax is how much more you have to pay based on a percentage of the initial cost. The tax percent in this case is 8%. Since the console costs $300, we take 8% of $300 and charge it as the tax.

$300 * 8% = $300 * 0.08 = $24

If done by hand,  move the decimal place on 0.08 to the left 2 times

0.08

00.8

008

This will give you 8. Multiply 8 by $300 which will give you $2400, next move the decimal to the right 2 times.

$2400.

$240.0

$24.00

Now you have $24

A farmer planted corn in a square field. One side of the field measures 39 yards. What is the area of the cornfield?

Answers

Answer:

The area of the cornfield is 1,529 yards.

Step-by-step explanation:

In this case, since the statement indicates that it is a square field, you have to use the formula to calculate the area of a square, which is:

A=a², where:

A is the area

a is the lenght of side

The statement says that one side measures 39 yards, so this would be a, and you can replace this value on the formula:

A=39²

A=1,521

According to this, the answer is that the area of the cornfield is 1,529 yards.

Step-by-step explanation:

A cube has the same dimensions on each side, and the unit is 1 unit cube, none of the other options match.

You can easily rule out, B & D. That leaves you with A & C, and A makes the most sense, since 1 cubic unit would be the volume, and this question is only asking for the side length.
