Answer:

(3, 2).

Step-by-step explanation:

It must be in the area containing  the squares

Answer:

u = 14

t =8

Step-by-step explanation:

To make the triangles congruent

3u = u+28

Subtract u

3u-u = u+28-u

2u = 28

Divide by 2

2u/2 = 28/2

u = 14

12t = 16t -32

Subtract 16t

12t-16t = 16t-32-16t

-4t = -32

Divide by -4

-4t/-4 = -32/-4

t = 8

Answer:

t = 8

u = 14

Step-by-step explanation:

For the triangles to be congruent, the sides must be equal.  Set each side on the first triangle equal to the corresponding side on the second triangle.  

Solve.

u + 28 = 3u

28 = 2u

14 = u

12t = 16t -32

-4t = -32

t = 8

The two values for t and u are 8 and 14, respectively.

Answer:

71

Step-by-step explanation:

Because this triangle is an isosceles, the base angles are equal

the top angle is 38 and triangles add up to 180

so 180-38=142

then divide that by 2

which is 71 so x=71

Question:

If cos(θ) =-8/17 and sin(θ) is negative, then sin(θ) = ___  and tan(θ) =___.

Answer:

[tex]Sin\theta = \frac{-15}{17}[/tex]

[tex]Tan\theta = \frac{15}{8}[/tex]

Step-by-step explanation:

Given

cos(θ) =-8/17

Required

sin(θ) = __

tan(θ) =__

The first step is to determine the length of the third side

Given that

[tex]cos(\theta) = \frac{Adj}{Hyp}[/tex]

Where Adj and Hyp represent Adjacent and Hypotenuse

[tex]cos(\theta) = \frac{-8}{17}[/tex]

By comparison

[tex]Adj = -8\ and\ Hyp = 17[/tex]

Using Pythagoras

[tex]Hyp^2 = Adj^2 + Opp^2[/tex]

By Substitution

[tex]17^2 = (-8)^2 + Opp^2[/tex]

[tex]289 = 64 + Opp^2[/tex]

Subtract 64 from both sides

[tex]289 - 64 = 64 - 64 + Opp^2[/tex]

[tex]225 = Opp^2[/tex]

Take square roots of both sides

[tex]\sqrt{225} = \sqrt{Opp^2}[/tex]

[tex]\sqrt{225} = Opp[/tex]

[tex]15 = Opp[/tex]

[tex]Opp = 15[/tex]

The question says that sin(θ) is negative; This implies that θ is in the third quadrant and as such

[tex]Opp = -15[/tex]

From trigonometry

[tex]Sin\theta = \frac{Opp}{Hyp}[/tex]

[tex]Sin\theta = \frac{-15}{17}[/tex]

Also from trigonometry

[tex]Tan\theta = Sin\theta / Cos\theta[/tex]

[tex]Tan\theta = \frac{-15}{17} / \frac{-8}{17}[/tex]

[tex]Tan\theta = \frac{-15}{17} * \frac{-17}{8}[/tex]

[tex]Tan\theta = \frac{-15 * -17}{17 * 8}[/tex]

[tex]Tan\theta = \frac{15 * 17}{17 * 8}[/tex]

[tex]Tan\theta = \frac{15}{8}[/tex]

Answer:

OC is not a function

Step-by-step explanation:

It's not a function because the x cannot repeat.

Answer:

(a)80 degrees and 100 degrees

(b)58 degrees and 122 degrees.

(c)36 degrees and 54 degrees

(d)50 degrees and 40 degrees

(e)150 degrees

(f)70 degrees and 110 degrees

(g)60 degrees

Step-by-step explanation:

Definitions

(a)

If 4x and 5x form a linear pair, then:

4x+5x=180

9x=180

x=20

The angles are 80 degrees and 100 degrees respectively.

(b)

If (2x - 10) and (3x + 20) are a linear pair, then:

2x-10+3x+20=180

5x+10=180

5x=180-10

5x=170

x=34

The angles are:

2x-10=2(34)-10=58 degrees

3x+20=3(34)+20=122 degrees.

(c)

A pair of complementary angles are in the ratio 2:3

The angles will be:

[tex]\dfrac{2}{5} \times 90^\circ =36^\circ\\\dfrac{3}{5} \times 90^\circ =54^\circ[/tex]

(d)

The difference of complementary angles is 10°

Let the first angle =x

Let the second angle =y

Difference: x-y=10

Since they are complementary, x+y=90

Solving the two simultaneously

[tex]x-y=10\\x+y=90\\-----\\2x=100\\x=50^\circ\\$Recall: $x-y=10\\50-y=10\\y=50-10\\y=40^\circ[/tex]

The two angles are 50 degrees and 40 degrees respectively.

(e)If an angle is 5 times its supplement

Let the supplement =x

The other angle =5x

Therefore:

5x+x=180

6x=180

x=30

The angle will then be: 5 X 30 =150 degrees

(f)If one angle is 40 more than the other and the two angles are supplementary

Let the first angle be x

The second angle will be: x+40

x+x+40=180

2x=180-40

2x=140

x=70

The two angles are 70 and 110 degrees respectively.

(g)

Let the angle =x

Its Supplement = 180 -x

Its complement =90 -x

The supplement of the angle is four times its complement.

180-x=4(90-x)

180-x=360-4x

4x-x=360-180

3x=180

x=60

The angle is 60 degrees.

calculator

Answer:

The yearly growth percentage is 5%

The worth of the company in 2010 is 433 million of dollars approximately

Step-by-step explanation:

The annual growth percentage;

We can write the equation of w as follows;

W = 266 (1 + 0.05)^t

Compare this with ;

W = I(1 + r)^t

Where W is the worth at a particular year

I is the initial worth at year 2000

r is the rate of increase per year

and t is the time since 2010

where it is the 0.05 that represents the yearly growth percentage (r)

0.05 as a percentage is 5/100 which is 5%

Now, we want to calculate the worth of the company in the year 2010

The first thing to do here is to calculate the value of t.

The value of t is the difference between the years 2000 and 2010 and that is 2010-2000 = 10 years

Now to find the worth at 2010, simply substitute that value of t = 10 in the equation

Thus;

W = 266(1.05)^10

W = 433.2859707228

Which is approximately 433

Answer:

380 square inches

Step-by-step explanation:

We are given the measurements of the Rectangular Prism as

8 inches by 9 inches by 10 inches

Where based on the order of arrangement:

8 inches = Length

9 inches= Width

10 inches = Height

Step 1

Find the amount of wrapping paper needed

Perimeter = 2L + 2W

= 2 × 8 + 2 ×9

= 16 + 18

= 34 inches

Base = L × W

= 8 × 9

= 72 inches

Surface Area of the Rectangular Prism =PH + 2B

Where P = Perimeter

H = Height

B = Base

= 34 × 10 + 2× 72

= 340 + 144

= 484 square inches

The area of the Rectangular prism = 484 square inches

Step 2

So we were told that she used wrapping paper the measured 2 feet by 3 feet.

We would convert the values in feet to inches

1 ft = 12 inches

Length = 2 ft = 2 × 12 = 24 inches

Width = 3 ft = 3 × 12 = 36 inches

We find the area of the wrapping paper

Length × Width = 24inches × 36 inches = 864 square inches.

Step 3

The amount of square inches of wrapping paper left over is calculated as:

Area of the wrapping paper used - Area of the Rectangular prism

= 864 square inches - 484 square inches

= 380 square inches.

Therefore, the amount of square inches of wrapping paper left over is 380 square inches.

Answer:

Step-by-step explanation:

The constant term of x^2 + 13x – 48 factors into either (3)(-16) or (-3)(16).

Note how 16 - 3 = 13, which is the coefficient of the middle term.  Thus, the factors are

(x + 16)(x - 3) which is equivalent to x^2 + 16x - 3x - 48, or x^2 + 13x - 48.

The factored form of the given polynomial  is (x - 3)(x + 6)

Since the equation is [tex]x^2 + 13x - 48[/tex]

Now

The four-term polynomial is

[tex]x^2 + 16x - 3x - 48[/tex]

x(x + 16) - 3(x + 16)

(x - 3)(x + 6)

Here polynomial represents the expression that includes the additions, subtraction, etc

Therefore, The factored form of the given polynomial  is (x - 3)(x + 6)

Answer:

r = -4

Step-by-step explanation:

If M is the midpoint of DE, that would mean that the distance from M to D and M to E would be the same.

This creates the equation 1-8r=13-5r.

Now it's just simple algebra.

You add 8r to both sides, creating 1=13+3r. Then, you subtract 13 from both sides, getting 3r=-12. Dividing both sides by 3 and solving for r, you get r=-4.

Checking our answer, you see that 1-8(-4)=1-(-32)=1+32=33, and 13-5(-4)=13-(-20)=13+20=33.

option d on edge trash

Step-by-step explanation:

Answer:

B.

Step-by-step explanation:

Well if the y intercept is -5 and the y intercept is the point on the line that touches the y axis we can cross out choices C. and D..

And the slope is positive so we can cross out A. So the final answer is B.

Answer:

B

Step-by-step explanation:

We can solve this by reasoning:

GIven that the equation is f(x) = (1/2)x - 5

we first notice that the gradient (represented by the x-coefficient) is (1/2). Because it is a postie value, we expect the graph to have a positive slope (i.e going from bottom left to top right).

By observing the choices, only B and C have this gradient, hence we can ignore A and C

Further, we can see that the constant term in the equation is (-5), this means that the y-intercept occurs at y = -5.

We can see that for C, the graph crosses the y-axis at y = 5, Hence we can ignore C, leaving B as the correct answer

Point (-3, 0) is required solution to the inequality. Hence option B. is correct.

Inequality can be define as the relation of equation contains the symbol of ( ≤, ≥, <, >) instead of equal sign in an equation.

As from graph,
The inequality can be define as -[tex]y > \frac{4}{3}x+4[/tex]
And the point(-3, 0) lies on the boundary line.
Which gives the solution to the given inequality.

Thus, point (-3, 0) is required solution to the inequality.
