Answer
20 ?
Step-by-step explanation:
Answer: [tex]k=-20[/tex]
Move all terms to the left
[tex]2-k-(22)=0[/tex]
Add all the numbers together, and all the variables
[tex]-1k-20=0[/tex]
Move all terms containing k to the left, all other terms to the right
[tex]-k=20\\k=20/-1\\k=-20[/tex]

Determine two pairs of polar coordinates for (4,4) when 0° < θ < 360°
a(4√2, 45°), (-4√2, 225°)
b(4√2, 315°), (-4√2, 135°)
c(4√2, 135°), (-4√2, 315°)
d(4√2, 225°), (-4√2, 45°)
Answer: option a.
Step-by-step explanation:
In polar coordinates we have that:
x = r*cos( θ)
y = r*sin( θ)
we know that x = 4 and y = 4. now let's analyze the options:
a) x = 4√2*cos(45°) = 4 nice.
y = -4√2*sin(225°) = 4 nice
Option a is correct
b) x = 4√2*cos(315°) = 4 nice
y = -4√2*sin(135°) = -4 incorrect
option b is not correct
c) x = 4√2*cos(135°) = -4 incorrect
Option c is not correct
d) x = 4√2*cos(225°) = -4 incorrect
option d is not correct

1 min to fill 16.50 gallons what is the constant
Answer:constant is 2/33
Step-by-step explanation:
1 min to fill 16.50 gallons
Time(t) varies directly as volume(v)
t α v
t =k x v Where k is constant
1=k x 16.50
k=1/16.50
k=2/33
Constant is 2/33
Select the three side lengths, in centimeters (cm) that form a right triangle.
5 cm
6 cm
8 cm
10 cm
11 cm
12 cm
A right triangle can be made using the side lengths 3,4 5, so we can find multiples of those numbers. If you multiply 3,4 and 5 by 2 you get 6,8,10
The answer would be 6cm, 8cm, 10cm

Kevin goes to the grocery store and buys a box of cereal, a family size box of cereal, a candy bar, and a king sized candy bar. He notices that the family sized box of cereal is twice as big as the regular box of cereal and the king size candy bar is twice as big as the regular candy bar. Kevin believes that because the family sized box of cereal and king sized candy bar are twice the size that the volume is also twice the size. Is Kevin correct in his thinking?
a businesswoman sells a bag for $52.32, thereby making a profit of 9% on the cost of her. calculate the selling price the businesswoman should ask in order to make 20% profit
Answer: $57.6
Step-by-step explanation:
Given : A businesswoman sells a bag for $52.32.
Let cuurent selling price : SP = $52.32
As they are making 9% profit now.
That means SP= Cp +0.09 CP , where Cp is the cost price of bag.
i..e [tex]52.32=Cp(1+0.09) \ \text{[Substituted value of SP in LHS and taking Cp common outside in RHS]}[/tex]
[tex]\Rightarrow\ 52.32=Cp(1.09)\Rightarrow\ CP=\dfrac{52.32}{1.09}=48[/tex]
i..e Cost price of bag = 48
Selling price to gain 20% profit = Cp+0.20CP
= CP(1+0.20)
=48 (1.20)
= 57.6
Hence, the selling price the businesswoman should ask in order to make 20% profit = $57.6

Answer:
D. 96
F. 32
Step-by-step explanation:
The inequality 3x ≥ 96, means that x and 3 must be multiplied to get a product that is greater than 96. So to figure this out, you must plug in the numbers given for x, like so:
3x ≥ 96
A. 3(31) ≥ 96
93 ≥ 96 This is incorrect since 93 is not greater than 96
A tip that makes this easier is that, you can see that 31 multiplied by 3 is 93, which is only a couple numbers off 96, so all numbers after 31 will result in a product greater than 96. For example:
D. 3(96) ≥ 96
288 ≥ 96 This inequality is correct
F. 3(32) ≥ 96
96 ≥ 96
The inequality sign states that the number must be either greater or equal to 96, which it is.

Answer:
C. (5x + 6) (5x - 6)
Step-by-step explanation:
25 is a perfect square, meaning its two factors are identical (5), and 36 is also a perfect square with two identical factors (6). With this information, we can split the expression below like this:
[tex]25x^2 - 36\\(5x ) (5x )[/tex]
Since 36 is negative, we have to have a positive 6 and a negative 6:
(5x - 6) (5x + 6)
The height of a triangle is 18 inches. Find the length of the base if the area of the triangle is 63 square inches
Answer:
7 inches
Step-by-step explanation:
The area of a triangle is found by
A = 1/2 bh
We know the height is 18 and the area is 63
63 = 1/2 (b)(18)
63 = 9b
Divide each side by 9
63/9 = 9b/9
7 = b
The base is 7 inches
Answer:
7 inches
Step-by-step explanation:
Area = ½ base × height
63 = ½ × base × 18
63 = 9 × base
base = 7 inches

The value of cos(315°) is 0.7071 and the value of sin(315°) is -0.7071.
What are trigonometric ratios?The sides and angles of a right-angled triangle are dealt with in Trigonometry. The ratios of acute angles are called trigonometric ratios of angles. The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec).
Given that, cos(315°) and sin(315°).
So, the values are

What is the slope of the line
Answer:
4/5
Step-by-step explanation:
There are so many points on the graph whose coordinates are impossible to estimate. Look for two "nice" points--points with integer coordinates. The line passes through (-2, 0) and (3, 4).
Slope = rise / run. It's the ratio of vertical change to horizontal change as you move from one point on the line to another.
Moving from (-2, 0) to (3, 4), the vertical change is 4 - 0 = 4.
The horizontal change is 3 - (-2) = 5.
The slope is 4/5
To generate leads for new business, Gustin Investment Services offers free financial planning seminars at major hotels in Southwest Florida. Gustin conducts seminars for groups of 25 individuals. Each seminar costs Gustin $3,500, and the commission for each new account opened is $5,000. Gustin estimates that for each individual attending the seminar, there is a 0.01 probability that he/she will open a new account.
(a) Determine the equation for computing Gustin's profit per seminar, given values of the relevant parameters. Profit = (New Accounts Opened × ) –
(b) What type of random variable is the number of new accounts opened? (Hint: Review Appendix 11.1 for descriptions of various types of probability distributions.)
(c) Choose the appropriate spreadsheet simulation model to analyze the profitability of Gustin's seminars. (I) (II) (III) (IV) Would you recommend that Gustin continue running the seminars?
(d) How many attendees (in a multiple of five, i.e., 25, 30, 35, . . .) does Gustin need before a seminar's average expected profit is greater than zero?
Answer:
a) profit = (new account opened x 5000) -3500
b) Opening account is binomial distribution with n =25 and p = 0.01
c) Probability of loss is 0.77781 --I don't recommend the company that it running the seminar
d) n ≅ 71

A. True, a rhombus is a parallelogram with equal sides. A rhombus has four congruent sides.
B. True, but there are two other ways to find the area of a rhombus: there is the "diagonals" method and the "trigonometry" method.
C. False, the area of a rhombus is not less than the area of a parallelogram because it will depend on the diagonals.
D. False, a parallelogram is not always a rhombus because the dimensions and other attributes of a parallelogram may vary while the rhombus will remain equal for all aspects.
E. True, if you use the base times height formula but if you used any of the other formulas this would be false.
Find the equation of the line that has the given properties. Write the equation in slope-intercept form, if possible.
Contains (3, 3); perpendicular to the line y = 2x - 1
Answer:
y = (-1/2)x + 9/2
Step-by-step explanation:
the equation of a straight line can be written as;
y = mx + c ......1
Where;
m = slope
c = intercept
For two lines to be perpendicular their slope must be opposite reciprocal of each other.
m1 × m2 = -1 .....2
Given;
The equation Contains (3, 3); and perpendicular to the line y = 2x - 1
Slope of the given equation m1 = 2
Slope of the line m2; substituting m1 to equation 2.
2 × m2 = -1
m2 = -1/2
So,
y = (-1/2)x + c
To solve for c, let's substitute the given point on the line; (3,3).
3 = (-1/2)(3) + c
3 = -3/2 + c
c = 3 + 3/2
c = 9/2
Therefore, the equation of the line that has the given properties is;
y = (-1/2)x + 9/2
