A principal needs to order 1,437 T-shirts for students at her school. She rounds to the nearest hundred

to estimate the number of T-shirts to order. Will there be enough T-shirts for all the students? Explain.

There will not be **enough T-shirts **for all the students

From the question, the given parameters are:

Number of T-shirt = 1437

From the question, we understand that the principal **approximates **the number of T-shirts to the **nearest hundred**

When the number of **T-shirts **is approximated to the nearest hundred, we have

Approximation = 1400

By comparison, 1400 is **less than** 1437

This means that the T-shirts will not be **enough**

2. Bob and Joy Salkind want to save $50,000 in 5 years for home improvement projects. If the

Bank of Aventura is paying 8% interest compounded quarterly, how much must they deposit

now to have the money for the project?

The amount of money should be **invested **to obtain **interest **of amount 50000$ is 34,000$(approximately)

The practice of adding **interest** to the **principal amount** of a loan or deposit is known as **compound interest**, sometimes known as interest on principal and interest**.** Reinvesting interest, or adding it to the lent **capital** rather than paying it out or seeking repayment from the borrower, results in interest being received on the principal amount plus interest collected previously.

[tex]{\displaystyle A=P\left(1+{\frac {r}{n}}\right)^{nt}}[/tex]

Where,A is the total sum.

P equals the initial principal amount.

The nominal yearly interest rate is r.

The compounding frequency is n.

t is the total amount of time that the interest is charged (expressed using the same time units as r, usually years).

The final value less the beginning investment yields the entire compound interest.

On substituting the values we get that initial investment of approximately 34000$

The **total area** for the **parallelogram**-shaped tiles Felix needs to buy exists 80cm² at the price of $40.

In calculating the **area **of a parallelogram, the **base **exists multiplied by the height, in an exact way as computing the area of a **rectangle**.

Given that, the base of one **parallelogram**-shaped tile exists 4cm with a height of 2 cm.

Area of one parallelogram shaped tile = 4cm × 2cm

Area of one parallelogram-shaped tile = 8cm²

**Total area** for the 5black and 5white tiles = 10 × 8cm²

Total area for the 5black and 5white tiles = 80cm²

1,936 divided by 8 in long division

Answer:

242.

Step-by-step explanation:

Basically, you have to put the 2 numbers "1936" and "8" down. After you put the 2 numbers down, you have to figure out how many times 8 goes into 19 which is 2 times.

You put the 2 above the 1 in 1936. After you put the 2 up there, you have to figure out 2 x 8 which is 16. You have to put the 16 below the 19 and subtract 19 by 16 which is 3.

After you finish that equation, you must bring the 3 down next to the 3 you wrote down on 19 - 16. The number turns into 33 and you have to figure out how many times 8 goes into 33 which is 4 times. You put the 4 next to the 2 above and then do 4 x 8 which is 32. You do 33 - 32 which is 1.

You bring the 6 down in 1936. It turns into a 16. You now have to figure out how many times 8 goes into 16 which is 2 times. You put 2 next to the 2 and the 4 above and that turns the number into 242.

You then have to do 2 x 8 which is 16 and put 16 under the 16 from 33 - 32. That'll make an equation which is 16 - 16 which is 0. There is no remainder and all the numbers were added above so 242 is your answer.

Find sin(2x), cos(2x), and tan(2x) from the given information.

tan(x) = − 4/3 , x in Quadrant II

**Answer:**

**Step-by-step explanation:**

Starting from tan x, you can find sec x, because of the trigonometric identity 1 + tan2 x = sec2 x.

1 + (-4/3)2 = 1 + 16/9 = 25/9 = sec2 x.

So sec x = ±√(25/9) = ±5/3. But since x is in Quadrant II, sec x has to be negative. That's because sec x has the same sign as cos x, because sec x = 1 / cos x. We know that cos x is negative is Quadrant II, therefore so is sec x. So sec x = -5/3.

Since sec x and cos x are reciprocals of each other, cos x = 1/sec x = -3/5.

Now use the identity sin2 x + cos2 x = 1, to find sin x:

sin2 x + (-3/5)2 = 1

sin2 x + 9/25 = 1

sin2 x = 16/25

sin x = ±4/5

Again, we know that sin x is positive in Quadrant II, so sin x = 4/5.

Now that we know sin x and cos x, we can use the double angle formulas to find sin 2x and cos 2x.

sin 2x = 2 sin x cos x = 2 (4/5) (-3/5) = -24/25

cos 2x = cos2 x - sin 2 x = (-3/5)2 - (4/5)2 = 9/25 - 16/25 = -7/25

Finally use the identity tan x = sin x / cos x to find tan 2x:

tan 2x = sin 2x / cos 2x = (-24/25) / (-7/25) = -24/-7 = 24/7

A triangle, ABC, has angle measures of 45°, 45°, and 90° and two congruent (equal) sides. How would this triangle be classified?

O Isosceles acute

O Scalene acute

O Scalene right

O Isosceles right

**Answer:**

(d) Isosceles right

**Step-by-step explanation:**

You want to know the classification of a triangle with angles 45°-45°-90°.

ClassificationThe largest angle is 90°, a right angle. Any triangle containing a right angle is a * right triangle*.

Two of the angles have the same measure. This means the triangle is an **isosceles triangle**.

**The triangle is classified as an isosceles right triangle**.

__

*Additional comment*

A triangle whose largest angle is less than 90° is an *acute* triangle. If the largest angle is greater than 90°, it is an *obtuse *triangle.

If no sides are the same length, the triangle is *scalene*. If two sides are the same length, the triangle is *isosceles*. If all three sides are the same length, it is an *equilateral* triangle.

Larger angles are opposite longer sides, so if angles are the same, their opposite sides are the same.

It can be worthwhile to remember that the side length ratios in an isosceles right triangle are 1 : 1 : √2.

You have to find a line perpedicular to the line y=1/2x-3 that passes through the point (-5,2)

Given one line, to find another one perpedicular to it, you have to keep in mind that the slope of the perpedicular line is the negative inverse of the slope of the first one, that is:

Let the given line be:

[tex]y_1=mx+b[/tex]And the perpendicular line

[tex]y_2=nx+c[/tex]The slope of the perpendicular line will be:

[tex]n=-\frac{1}{m}[/tex]So for the line

[tex]y=\frac{1}{2}x-3[/tex]The slope is

[tex]m=\frac{1}{2}[/tex]For the perpedicular line it will be:

[tex]\begin{gathered} n=-\frac{1}{\frac{1}{2}}=-1\cdot\frac{2}{1} \\ n=-2 \end{gathered}[/tex]Now that the slope of the perpendicular is determined, use the point slope form to find the equation of the perpedicular line:

[tex]y-y_1=m(x-x_1)[/tex]Replace the with m=-2 and (-5,2)

[tex]\begin{gathered} y-2=-2(x-(-5)) \\ y-2=-2(x+5) \\ y-2=-2x-10 \\ y=-2x-10+2 \\ y=-2x-8 \end{gathered}[/tex]The equation perpendicular to
