Answer:

C. 9

Step-by-step explanation:

y = -4x^2 + 2kx

subtitute 3:

y = -4(9)^2 + 2k(9)

y = -4(81) + 18k

let y = 0

=> 0 = -324 + 18k

=> k = 324/18 = 9

this is my calculations hope it helps

Answer:

  ΔABC ≅ ΔEFD

Step-by-step explanation:

The congruence statement will list corresponding parts of the figures in the same order.

The left side of the statement is ΔABC, so we need to find the parts that correspond to A, B, and C, and list them in the same order. We notice that A is the marked angle, as is E. B is the other end of the line segment with 1 hash mark, as is F. Then corresponding vertices are ...

Consequently, the congruence statement must be ...

  ΔABC ≅ ΔEFD

Answer: A

Step-by-step explanation:

You have:

[tex]20cos(\frac{2\pi }{5} x)=10\sqrt{2}[/tex]

Begin by dividing both sides by 20 to get:

[tex]cos(\frac{2\pi }{5} x)=\frac{\sqrt{2} }{2}[/tex]

Take the arccosine of both sides to get:

[tex]arccos(cos(\frac{2\pi }{5} x))=arccos(\frac{\sqrt{2} }{2})[/tex]

[tex]\frac{2\pi }{5} x=arccos(\frac{\sqrt{2} }{2} )[/tex]

First of all, lets find the right side. Cosine of what gives sqrt 2 over 2? That would be pi/4, plus 2npi. Another solution would be 7pi/4, plus 2npi. We have:

[tex]\frac{2\pi }{5} x=\pi /4+2n\pi[/tex]

[tex]\frac{2\pi }{5} x=7\pi /4+2n\pi[/tex]

Isolate 'x' to get:

[tex]x=\frac{5}{2\pi } (\pi /4+2n\pi)=\frac{5}{8} +5n[/tex]

[tex]x=\frac{5}{2\pi } (7\pi /4+2n\pi)=\frac{35}{8} +5n[/tex]

Answer:

75%

Step-by-step explanation:

Given:

Total = 16 buttons

Large = 12 buttons

To Find:

What percentage of the buttons were large?

Solution:

Since, we know that it asking for percentage(%) of buttons were large. As well as total is 16 buttons and 12 button were large.

Thus,

Formula : a/b × 100

Let's

a = 12

b = 16

Therefore,

12/16 × 100

.75 × 100

= 75%

Hence, the percentage of the buttons that Rita bought were large is 75%

hope this helps.

Answer:

x=0.38

Step-by-step explanation:

3x+0.15=1.29    1. -0.15 on both sides

3x=1.14  2. /3 on both sides

x=0.38

well, the total amount is "x", which oddly enough is 100%, and we also know that 22% of that is 27.9 millions, so

[tex]\begin{array}{ccll} \stackrel{millions}{amount}&\%\\ \cline{1-2} x & 100\\ 27.9& 22 \end{array} \implies \cfrac{x}{27.9}=\cfrac{100}{22} \\\\\\ 22x=2790\implies x=\cfrac{2790}{22}\implies x\approx 127[/tex]

The ground speed of the plane is 402 mph

We have given,

A plane leaves an airport traveling at 400 mph in the direction n 45° e. a wind is blowing at 40 mph in the direction n 45° w.

Now, Draw a right triangle with 400 and 40 as the two legs.

This is a right angle because 45 degrees NE is perpendicular to 45 degrees NW.

So, the two side lengths are 400 and 40

Using the Pythagorean theorem,

(a^2 + b^2 = c^2)

[tex]400^2+40^2=c^2\\\\c^2=160000+1600\\c^2=161600\\c=401.99[/tex]

Therefore the answer is 401.995, or 402mph.

Answer: $7,500

Step-by-step explanation:

Use the formula: SI = P(1 + rt)

SI = 5000(1 + 0.05[10])

SI = 5000 + 2500

SI = $7,500

After 10 years, your balance should be $7,500

Answer:

An arithmetic sequence is an ordered set of numbers where the difference between each consecutive term is the same (this is called the "common difference").

The formula for each term in an arithmetic sequence is:

[tex]\sf a_n=a+(n-1)d[/tex]

where:

Example

Sequence:  3, 10, 17, 24, 31, ...

The first term in the sequence is 3, therefore a = 3

The common difference can be found by subtracting one term from the next:  d = 10 - 3 = 7

Substituting these values into the equation for the nth term:

[tex]\implies \sf a_n=3+(n-1)7[/tex]

[tex]\implies \sf a_n=3+7n -7[/tex]

[tex]\implies \sf a_n=7n -4[/tex]

Therefore, if we want to find the 5th term of the sequence, simply input
n = 5 into the found equation:

[tex]\implies \sf a_5=7(5)-4=31[/tex]

Yes we can find terms

Step-by-step explanation:

Answer:

∠1 = 130°

∠2 = 50°

∠3 = 130°

Step-by-step explanation:

As we can see Angles 1 and 50° are on a straight line. As :

Angles on a straight line add up to 180. So :

50 + ∠1 = 180

∠1 = 180-50

∠1 = 130

As we can angles 1 and 2 are on a straight line. As :

Angles on a straight line add up to 180. So :

∠1 + ∠2 = 180

As we worked out ∠1 we can substitute that in to work out ∠2 :

130 + ∠2 = 180

∠2 = 180-130

∠2 = 50

As we can angles 2 and 3 are on a straight line. As :

Angles on a straight line add up to 180. So :

∠2 + ∠3 = 180

As we worked out ∠2 we can substitute that in to work out ∠3 :

50 + ∠3 = 180

∠3 = 180-50

∠3 = 130

Answer:

58

Step-by-step explanation:

First, we subtract 32 from 90(90deg-32deg) since the entire corner of the problem is the main area we will be focusing on. We get 58deg, and that's your answer!

Answer:

x = 58

Step-by-step explanation:

Look at the picture I have below.

It shown a complementary and supplementary angle.

As we can see there is complementary and supplementary angle in the given picture you have.

Also note that:

Complementary = 90 degree

Supplementary = 180 degree

Since we are solving for x and it close to complementary thus the equation can be written as:

x + 32 = 90

Subtract both sides by 32

x + 32 - 32 = 90 - 32

90 - 32 = 58

Hence x = 58

The given information none of the statements about triangle LMN confirmed as true.

Based on the given options, "Check all that apply," I'll evaluate each statement about triangle LMN:

The triangle is scalene: A scalene triangle is a triangle with three unequal side lengths. Since no information is provided about the side lengths of triangle LMN,  determine if it is scalene. Thus, it cannot be confirmed as true.

The triangle is equilateral: An equilateral triangle is a triangle with three equal side lengths. Without any information about the side lengths of triangle LMN, determine if it is equilateral. Thus, it cannot be confirmed as true.

The triangle is isosceles: An isosceles triangle is a triangle with at least two equal side lengths. Without any information about the side lengths of triangle LMN,  determine if it is isosceles. Thus, it cannot be confirmed as true.

The triangle is a right triangle: A right triangle is a triangle with one right angle (90 degrees). No information is given about the angles of triangle LMN, so determine if it has a right angle. Thus, it cannot be confirmed as true.
