Answer 2

Answer:

Step-by-step explanation:

In a kite adjacent sides are equal.

GH = GF

2a - 4 = 30 {Add 4 to both sides}

2a = 30 +4

2a = 34 {Divide both sides by 2}

a = 34/2

a = 17

JF = JH

3b + 6 = 24 {Subtract 6 from both sides}

3b = 24 - 6

3b = 18 {Divide both sides by 3}

b = 18/3

b = 6

OPTION B

Pre-calc, Which statement correctly uses limits to determine a vertical asymptote of _____ (image attached)

Answers

Answer:

Option D

Step-by-step explanation:

Given the function [tex]g(x)=\frac{-7(x-5)^2(x+6)}{(x-5)(x+5)}[/tex], we see that [tex](x-5)[/tex] appears in both the numerator and denominator which cancel out to be [tex]\frac{-7(x-5)(x+6)}{(x+5)}[/tex]. This means that there's a vertical asymptote at [tex]x=-5[/tex] for the denominator to be 0.

Additionally, the limit of the function g(x) as x approaches -5 from the left side is -∞. The limit of the function g(x) as x approaches -5 from the right side is ∞. See the attached graph for a visual of these limits.

In conclusion, option D is correct.

Answers

Step-by-step explanation:

I'm assuming this is an isosceles triangle (cuz those two angles are equal right?)

since it's an Isosceles triangle,

y = 9

Answer:

y is 9, the sum of all angles is 180 degrees, so you take 180/9 and thats 20 but you can see 9 and y is about the same length so y is 9 and the other side is 11

Step-by-step explanation:

im guessing honestly but im pretty sure its 9, sorry if im wrong, have a good day :)

On a coordinate plane, triangles P Q R and S T U are shown. Triangle P Q R has points (4, 4), (negative 2, 0), (negative 2, 4). Triangle S T U has points (2, negative 4), (negative 1, negative 2), (negative 1, negative 4). Complete the statements to verify that the triangles are similar.

Answers

Answer:

See Explanation

Step-by-step explanation:

According to The Question,

Given That, On a coordinate plane, ΔPQR and ΔSTU are shown. ΔPQR has points (4,4) , (-2,0) , (-2,4). ΔSTU has points (2,-4) , (-1,-2) , (-1,-4).

We know, Two triangles are said to be similar if their corresponding angles are equal and the corresponding sides are in proportion.

The distance between two points on the coordinate plane is given as:

Distance = [tex]\sqrt{(x_{2}-x_{1})^{2} + (y_{2}-y_{1})^{2} }[/tex]

Therefore, in triangle PQR:

IQRI = [tex]\sqrt{(-2_{}-(-2)_{})^{2} + (4_{}-0_{})^{2} }[/tex] = 4

IPQI = [tex]\sqrt{(-2_{}-4_{})^{2} + (0_{}-4_{})^{2} }[/tex] = √52

IPRI = [tex]\sqrt{(-2_{}-4_{})^{2} + (4_{}-4_{})^{2} }[/tex] = 6

Now Similarly, In triangle STU

ISTI = [tex]\sqrt{(-1_{}-2_{})^{2} + (-2_{}-(-4)_{})^{2} }[/tex] = √13

ISUI = [tex]\sqrt{(-1_{}-2_{})^{2} + (-4_{}-(-4)_{})^{2} }[/tex] = 3

ITUI = [tex]\sqrt{(-1_{}-(-1)_{})^{2} + (-4_{}-(-2)_{})^{2} }[/tex] = 2

Now, Verifying that the triangles are similar

|QR| / |TU| = 4/2 = 2

|PR| / |SU| = 6/3 = 2

|PQ| / |ST| = √52 / √13 = 2

Hence, |QR| / |TU| = |PR| / |SU| = |PQ| / |ST|

Therefore, △PQR and △STU are similar triangles since the ratio of their sides are in the same proportion.

Answer: the answer is Complete the statements to verify that the triangles are similar.

StartFraction Q R Over T U EndFraction = ✔ 2

StartFraction P R Over S U EndFraction = ✔ 2

StartFraction P Q Over S T EndFraction = StartFraction StartRoot 52 EndRoot Over StartRoot 13 EndRoot EndFraction = ✔ 2

Therefore, △PQR ~ △STU by the ✔ SSS similarity

What is the area of the parallelogram?

Answers

Answer:

Step-by-step explanation:

The height is connected to the base of 16cm

Area = b * h

b = 16

h = 5

Area = b * h

Area = 16 cm * 5 cm

Area = 80 cm^2

Answer:

The area of parallelogram is 80 cm ².

Step-by-step explanation:

We have ,

A parallelogram having

Base = 16 cmLength = 13 cmHeight = 5 cm

To Find :-

The area of parallelogram

Solution :-

Using Formula

Area of parallelogram = base × height

substitute the values

Area of parallelogram = 16 cm × 5 cm

Answers

Answer:

32. ∛((x-7)/4) = f^(-1)(x)

33. -10x - 9

Step-by-step explanation:

32. We want to switch f(x) and x, and then solve for f(x) to get the inverse.

x = 4f(x)³ + 7

subtract 7 from both sides

x -7 = 4f(x)³

divide both sides by 4

(x-7)/4 = f(x)³

cube root both sides

∛((x-7)/4) = f(x)

make f(x) f^(-1)(x) because this is now the inverse

∛((x-7)/4) = f^(-1)(x)

the second answer is correct

33. for composition, we can treat (f · g) (x) as attached picture (content filter!), so we plug g(x) into f(x). This results in

2(-5x-7) + 5

expand

-10x - 14 + 5

add

what is the degree of the simplest polynomial with integer coefficients that has √2 , 2 , √2 + i , and 2 + 2i as some of its zeros?

a. 6
b. 7
c. 8
d. 9

Answers

If the polynomial has integer coefficients, then any complex roots with non-zero imaginary part must occur along with their conjugates. If a + bi is a root, then so is a - bi.

The given polynomial would then have at least 6 roots: √2, 2, √2 + i and √2 - i, and 2 + 2i and 2 - 2i. So the minimum degree is (A) 6.
