Answer:

(D)

Step-by-step explanation:

Two triangles are similar if it satisfies the following properties:

1) Corresponding angles are congruent.

2) Corresponding sides are all in same proportion.

Here, ΔSTU and ΔVWX are given, where ∠S is congruent to ∠V.

To prove these two triangles similar, we need one more corresponding angle to be congruent.

And from all the options, (d) Angle U is congruent to angle X. will help in proving ΔSTU and ΔVWX similar triangles.

Therefore, (d) is correct.  

Answer:

d)Angle U is congruent to angle X.

Option 2

Step-by-step explanation:

When completing a proof, the statements and reasons should be directly connected. Since the reason listed next to the missing statement is Def of Complimentary Angles, the statement must be about angles adding to 90 degrees. The definition of Complimentary Angles is that two angles add to 90. This means option 2 is the answer.

Answer: The common denominator for 3/8 and 1/3 is 24

Step-by-step explanation:

3/8 and 1/3 can be multiplied by each other in the numerator and denominator: 3/8(3/3) = 9/24 and 1/3(8/8) = 8/24

Answer:

3250 is your total; p = 50n + 1900 is your equation.

Step-by-step explanation:

"p" represents total pay; "n" represents the number of copies he sells.

Base salary is 1900, and each copy sold gives him an extra 50

p = 50n + 1900 is your equation.

If he sells 27 copies. Plug in 27 for n

p = 50n + 1900

p = 50(27) + 1900

Simplify. Remember to follow PEMDAS. First, multiply, then add.

p = 50(27) + 1900

p = 1350 + 1900

p = 3250

Find the ratio of the two similar sides that both dimensions are given.

The smaller triangle aide that is 4 units is the similar side of the larger triangle given as 8 units.

8 / 4 =2, this means the larger triangle is 2 times the size of the smaller triangle, which also means the smaller triangle is 1/2 the size of the larger triangle.

X on the smaller triangle is 1/2 11 units which equals 5.5 units.

Y is 2 times 3, which equals 6 units.

x = 5.5

y = 6

Answer:

15x + 150

Step-by-step explanation:

Answer:

x=22, y=48

Step-by-step explanation:

If this is an isosceles triangle, then <G is equal to <J

<g = <j

x+44 = 3x

Subtract x from each side

x+44-x = 3x-x

44= 2x

Divide each side by 2

44/2 = 2x/2

22= x

The three angles of a triangle add to 180 degrees

<G + <J + <H = 180

x+44 + 3x + y = 180

22+44 +66 + y = 180

Combine like terms

132+ y =180

Subtract 132 from each side

132-132+y = 180-132

y = 48

Answer:

z1=3 cos (52 + i sin 52)

z2 =3 cos (124 + i sin 124)

z3 = 3 cos (196 + i sin 196)

z4 =3 cos (268 + i sin 268)

z5= 3 cos (340 + i sin 340)

Step-by-step explanation:

To find the fifth roots of 243 (cos 260° + i sin 260°).

z ^ 1/5 = r^1/5 ( cis ( theta + 360 *k)/5)  where k=0,1,2,3,4

So the first root of 243 (cos 260° + i sin 260°)  

is z1 =  243^1/5 ( cis ( 260 + 360 *0)/5)  

          3 cis ( 260/5)

        = 3 cis (52)

        = 3 cos (52 + i sin 52)

The second root of  243 (cos 260° + i sin 260°)  

is z2 =  243^1/5 ( cis ( 260 + 360 *1)/5)  

          3 cis ( 620/5)

        = 3 cis (124)

        = 3 cos (124 + i sin 124)

The third root of  243 (cos 260° + i sin 260°)  

is z3 =  243^1/5 ( cis ( 260 + 360 *2)/5)  

          3 cis ( 980/5)

        = 3 cis (196)

        = 3 cos (196 + i sin 196)

The fourth root of  243 (cos 260° + i sin 260°)  

is z4 =  243^1/5 ( cis ( 260 + 360 *3)/5)  

          3 cis ( 1340/5)

        = 3 cis (268)

        = 3 cos (268 + i sin 268)

The fifth root of  243 (cos 260° + i sin 260°)  

is z5 =  243^1/5 ( cis ( 260 + 360 *4)/5)  

          3 cis ( 1700/5)

        = 3 cis (340)

        = 3 cos (340 + i sin 340)

Simple interest rate = 3%.

Since the given invested amount = $5000, number of years of investment = 4 years, interest earned = $600. 600 = 5000 × R × 4, 600 = 20000R, Dividing both sides by 20000, we get 0.003 which is 3%.

Answer: C

Step-by-step explanation:

A rectangle has 90° angles.  So, the diagonal cuts the rectangle into two right triangles where the length (base) and the width (side) are the legs of the right triangle and the diagonal is the hypotenuse. Thus, the Pythagorean Theorem can be used: (leg a)² + (leg b)² = (hypotenuse)²

14² + 6² = hypotenuse²

196 + 36 = hypotenuse²

232 = hypotenuse²

√232 = √hypotenuse²

15.23 = hypotenuse

Factor theorem: if x-k is a factor of p(x), then p(k) = 0. The same can be said in reverse: if p(k) = 0, then x-k is a factor of p(x).

In this case, x-1 = x-k so k = 1. We'll plug this into f(x) below

f(x) = 14x^99 - 65x^56 + 51

f(1) = 14(1)^99 - 65(1)^56 + 51 ... replace every x with 1

f(1) = 14(1) - 65(1) + 51

f(1) = 14 - 65 + 51

f(1) = -51 + 51

f(1) = 0

The result is 0, so h(x) = (x-1) is a factor of f(x) = 14x^99-65x^56+51

Answer: Choice A) yes

This is an exponential function. Since each year the value of the bike decreases by 5%, each year, the value of the bike is 100%-5%=95% of it's original value. So after x years, the value of the bike would be 200(0.95)^x.

Answer:

(200 - (200 x 5 / 100))^Y

Step-by-step explanation:

As the initial value of the bike is $200, that would be a fixed number in our equation. Each year, this will lose 5% of its value, therefore, it would be another fixed value in it. Then, we have to exponentiate it by the number of years that have passed since the initial value (Y). As a result, the equation to model the situation would be this one:

(200 - (200 x 5 / 100))^Y

Answer:

m ≠5

Step-by-step explanation:

We cannot divide by zero, so the denominator cannot equal zero.  That is the only restriction on the domain.

4m-20 ≠ 0

Add 20 to each side

4m-20+20 ≠20

4m ≠20

Divide each side by 4

4m/4 ≠20/4

m ≠5

Answer:

m ≠ 5

——

Step-by-step explanation:

Make the equation equal to zero.

4m - 20 = 0

Solve for the restriction.

4m - 20 = 0

Add 20 to both sides.

4m = 20

Divide both sides by 4.

m = 5

Answer:

m ≠ 5

TJKL - different letters

for the first place you have 4 letters to choose from

for the second place you have 3 letters to choose from

for the third place you have 2 letters to choose from

for the last place you have only one letter

Therefore your answer is:

Set up the equation: 2x+37+3x+y=180 ⇒ 4x+y=143

2x+y+3y-21=180 ⇒2x+4y=201.

Solving for x and y, you get that y=37, thus making x=26.5

Now, for b to be perpendicular to a, 2x+37 must equal 90.

2*26.5+37=90, so b is perpendicular to a.

Whether 'b' is perpendicular to 'a' is determined by their dot product. If the dot product of 'b' and 'a' is zero, then 'b' is perpendicular to 'a'. However, without knowing the specific components of these vectors, a precise computation can't be made.

In mathematics, particularly in vector algebra, vectors are said to be perpendicular or orthogonal if their dot product is zero. This is because the dot product of two vectors encapsulates the angle between them, defined as A·B = |A||B|cos(θ), where θ is the angle. If θ is 90 degrees (indicating the vectors are perpendicular), cos(θ) becomes 0, thus the dot product should be zero.

Therefore, to determine whether 'b' is perpendicular to 'a', we need to compute their dot product. If their dot product equals zero, then we can conclusively say that 'b' is perpendicular to 'a'. Beyond this, you'd need to provide the components of vectors 'a' and 'b' for a specific computation.
