Answer:
Value of k is 74Step-by-step explanation:
Here we have been provided with the values of n and w that is 4 and -6 respectively.
Equation that we have,
k = 5n² + wSubstituting the values of n and w in the equation,
[tex] \implies \: \sf{k \: = \: 5(4) {}^{2} \: + \: ( - 6)}[/tex]
[tex]\implies \: \sf{k \: = \: 5(4 \times 4) \: + \: ( - 6)}[/tex]
[tex] \implies \: \sf{k \: = \: 5 \: (16) \: + \: ( - 6)}[/tex]
Multiplying 16 by 5,
[tex]\implies \: \sf{k \: = \: 5 \: \times 16 \: + \: ( - 6)}[/tex]
[tex]\implies \: \sf{k \: = \: 80 \: + \: ( - 6)}[/tex]
[tex]\implies \: \sf{k \: = \: 80 \: - \:6)}[/tex]
Subtracting 6 from 80,
[tex]\implies \: \red{\bf{k \: = \: 74}}[/tex]
Therefore, value of k is 74..!!

d. Who scored the least? _______
2. Vincent's weight is 6 kilograms more than Ezekiel's weight Daniel's is 3 kilograms less than Ezekiel's weight. The average weight of the 3 boys is 63 kilograms.
a. What is the weight of Vincent? ________
b. What is the weight of Ezekiel? ________
c. What is the weight of Daniel? _________
d. What is the total weight of the three boys? ____
Need Answer!! A.S.A.P
Formula to find average:
Total value / number of values
____________
1. Krista = 30
a) Des = 2(30) - 20 = 40
b) Dodie = 30 - 4 = 26
c) Average score = 40 + 30 + 26 / 3 = 32
d) Dodie scored the least marks.
_____________
2. Ezekiel = x
Vincent = 6 + x
Daniel = x - 3
Average = 63
63 = x + 6 + x + x - 3/3
63 × 3 = x + 6 + x + x - 3
189 = 3x + 3
189 - 3/3 = x
62 = x
a) Vincent = 6 + x = 68 kg
b) Ezekiel = x = 62 kg
c) Daniel = x - 3 = 59 kg
d) Total weight = 62 + 68 + 59 = 189 kg

. Find the remainder when x3 - 9x2 + 6x + 2 is divided by x - 1
Answer:
0
Step-by-step explanation:
when f(x) is divided by (x - h) then the remainder is f(h)
f(x) = x³ - 9x² + 6x + 2 with h = 1 , then
f(1) = 1³ - 9(1)² + 6(1) + 2 = 1 - 9 + 6 + 2 = 0
since the remainder is 0 then (x - 1) is a factor of f(x)
A round race track has a radius of 75 yards. What is the circumference of the race track?
Answer:
471.24
Step-by-step explanation:
The formula for circumference is 2×pi×r. Replace the r with 75 and multiply.
circumference of the race track = 471.24 yards.
What is circle?A circle is a two-dimensional figure formed by a set of points that are at a constant or at a fixed distance (radius) from a fixed point (center) on the plane. The fixed point is called the origin or center of the circle and the fixed distance of the points from the origin is called the radius.
Given,
radius of race track r = 75 yards
circumference of the park = 2πr
= 2×3.1416×75
= 471.24 yards
471.24 yards is the circumference of the race track.

Find the cost of purchasing 30 roses. Show how you know.
Answer:
90 dollars
Step-by-step explanation:
so first you need to solve for the rate of change or slope with the equation
y 2 - y1 / x2 - x1
here i think the independent variable is number of roses since the dollars rely on the number of roses (sorry for my explanation its kinda bad)
so since number of roses is independent we know that it is x and that the price in dollars is y
anyways we have to substitute two values into the equation
y 2 - y1 / x2 - x1
(3, 9) (6, 18)
18 - 9 / 6 - 3
9 / 3
3
knowing that the rate of change is 3, to find the price for 30 roses all we have to do is:
let p be price
p = 3x
p = 3(30)
p = 90 dollars

Which values complete the function?
F(x)= (X- ) (x+ )
Answer:
f(x)= -1(x-3)(x+4)
First blank: -1
2nd blank: 3
3rd blank: 4
Step-by-step explanation:
When the parabola is flipped upside down (opened downward) there should be a negative in front. So the first blank is -1. Also, this parabola has not been stretched or smashed, that's why the value is a 1. Again, negative, because its reflected (flipped).
The other two blanks will come from the x-intercepts. The curve crosses the x-axis at 3 and -4.
If x = 3, then
subtracting 3 from both sides
x - 3 = 0
That x-3 is the
x - blank in the problem. Fill in a 3.
If x = -4, then adding 4 to both sides,
x + 4 = 0
Likewise, this x+4 is the
x + blank
in the question. Fill in a 4.

You are considering adding a new food product to your store for resale. You are certain that, in a month, the minimum demand for the product will be 6 units while the maximum demand will be 8 units. The estimated demand for this new product in any given month is 6 units (p=0.1), 7 units(p=0.4), and 8 units(p=0.5). If you choose to purchase 7 units for resale this month, what is the probability of selling all 7 units?
Answer:
Using EMV analysis, the number of units of the new product should be purchased for resale = Purchase 7.
The maximum EMV of profit you can make is 270.
Explanation:
We can use the following method to solve the given problem
Solution:
Using EMV analysis,
EMV (Purchase 6 for resale)= 6(40)(0.1) + 6(40)(0.4) + 6(40)(0.5)=240
EMV (Purchase 7 for resale) = [6(40)-60](0.1) +7(40)(0.4) + 7 (40)(0.5) = 270
EMV (Purchase 8 for resale) = [6(40)-2(60)] (0.1) + [7 (40) - 60] (0.4) + 8(40)(0.5)= 260
Largest EMV= 270; Choose to purchase 7 units for resale.

A person distributed his property of Rs 1000000 among his three sons and one daughter. Each son got 27% of the property. How much did the daughter get?
[tex] \mathscr{HELP!!}[/tex]
Answer:
Rs 190000
Step-by-step explanation:
Total property = Rs 1000000
For 1 son= 27% of the property
For 3 sons=27%×3= 81%
For daughter=100%-81%=19%
Now,
For daughter
19% of Rs 1000000
19/100 × Rs 100000
Rs 190000
Hence the daughter will get Rs 190000
1. The diagram shown is two intersecting lines. The measure of <5is 47°.
(a) What is the measure of 27 ? How do you know. Explain your answer in complete sentences.
(b) Suppose the measure of 26 can be represented by (2x - 5). What equation can be written to solve
for the value of x?
(c) What is the value of x?
The measure of ∠7 is 47°. Angle 7 is a vertical angle to angle 5
Suppose the measure of ∠6 is represented represented by (2x - 5), the equation that can be use to solve for x is 42 + 2x = 180
The value of x is 69
Vertical opposite anglesVertically opposite angles are angles that are opposite one another at a specific vertex and are created by two straight intersecting lines.
Vertical opposite angles are congruent. Therefore,
a. ∠5 ≅ ∠7 (vertical angles)
Therefore, angles 5 and 7 are congruent angles.
∠7 = 47°
b. Suppose ∠6 = 2x - 5 . let's find x
Therefore,
∠5 + ∠6 = 180(angle on a straight line)
The equation to solve the above is as follows:
47 + 2x - 5 = 180
42 + 2x = 180
2x = 180 - 42
2x = 138
x = 138 / 2
x = 69

Answer:
a) <5 and <7 have congruent angles. That means that both angles are equal, they have the same measure. This means that the measure of <7 is 47°.
<7 = 47°
b) 5 and 6 are adjacent, so this is the equation that we have to do to solve for the value of x.
<5 + <6 = 180°
47° + (2x - 5)° = 180°
c) To solve the linear equation we need to isolate x.
47° + (2x - 5)° = 180°
(2x - 5)° = 180° - 47° = 133°
2x - 5 = 133
2x = 133 + 5 = 138
x = 138/2 = 69
What is the rectangular form of the polar equation?
Answer:
C
Step-by-step explanation:
r - rcosθ = 6
r - x = 6
r = 6 + x
r² = (6 + x)²
x² + y² = 36 + x² + 12x
y² = 36 + 12x
12x = y² - 36
x = y²/12 - 3

Larry wanted to buy a notebook computer. He had $700 to spend. The salesman tried to
sell Larry a computer that cost $850, but Larry said that was too expensive. The
salesperson said he could give Larry 25% off of the price if he used a coupon. Sales ta
is 9%. Could Larry afford the computer? How much would it cost?
Answer:
yes, $694.88
Step-by-step explanation:
You have to find the cost after applying the coupon and sales tax. First remove 25% from the price by finding 75% of the price. 850*.75=$637.5 after applying the coupon. Then you would have to increase it by 9% to account of sales tax, so multiply by 1.09. 637.5*1.09= $694.88 after sales tax. This means that Larry can very narrowly afford the computer.

If the function g(x) goes through the point
(-1,11), then the function -g(x) must go
through what point?
-
Help
Answer:
(-1,-11)
Step-by-step explanation:
Since the Transformation happened to the g(x)
where we multiplied g(x) by -1 and g(x) represents the y-value
so the y-value will be multiplied by -1
New y-value = 11*-1 = -11
so the New Point will be (-1,-11)

area is 310.4 ft2. What is the length of the apothem?
• How can you draw a diagram to help you solve the problem?
• How can you use the area of a regular polygon formula?
Answer:
9.7 ft
Step-by-step explanation:
Use the formula for the area of a regular polygon with "n" sides with lengths "s" and apothem a:
A= 1/2 ans
1. Substitute A= 310.4
2. n= 8 (for octagon)
3. s = 8 (length of side)
310.4 = 1/2 (a)(8)(8)
310.4= 32a
a= 9.7 ft
Length of apothem: 9.7 ft
