Answer:
36.5
Step-by-step explanation:
y= -x²+73x-520
which can be represented as ax²+bx+c
a= -1, b= 73, c = -520
for maximum value of y,
the formula is
c - (b² / 4a)
= -520 - (73² / 4×(-1))
= -520 - (5329 / -4)
= -520 + 1332.25
= 812.25
Solving for x,
812.25 = -x²+73x-520
or, x²-73x+ 1332.25 = 0
Solving,
x= 36.5

Solve the equation. u+3=7
Answer: 4
Step-by-step explanation:
u+3=7
u=7-3
u=4
The discriminant if a quadratic equation is negative. One solution is 4 + 7i. What is the other solution? *
7 - 4i
4 - 7i
- 4 + 7i
7 + 4i
==========================================================
Explanation:
When you have a quadratic in the form ax^2 + bx + c = 0, where a,b,c are real numbers, then a negative discriminant leads to having a pair of complex roots. The roots come in conjugate pairs meaning that p+qi is one root while p-qi is the other root. The p,q are real numbers.
In the case of 4+7i being one root, we have p = 4 and q = 7, since it matches with p+qi. The other root must be 4-7i since it matches with p-qi.
In short, we flip the plus to a minus when going from 4+7i to 4-7i. All of this applies when we have a,b,c as real numbers.
If we allowed a,b,c to be complex numbers, then the roots may not necessarily come in conjugate pairs.

Answer:
175.2 square feet
Step-by-step explanation:
The lateral area is the total area of the side faces. It excludes the area of the top and bottom "bases" of the prism.
It can be found by adding the areas of the four rectangles. The two you can't see have the same areas as the two you can see.
Since the height of each rectangle is 4 feet. the total area will be the product of that and the perimeter of the prism.
LA = Ph . . . . perimeter times height
LA = 2(L+W)h . . . . the perimeter is twice the sum of length and width
LA = 2(12.3 ft + 9.6 ft)(4 ft) = 2(21.9 ft)(4 ft) = 175.2 ft²
The lateral area of the prism is 175.2 ft².
__
The attachment shows scribbling on two of the faces that contribute to the lateral area. As stated above, the other two faces are the same size as these.

Step-by-step explanation:
20% of 85.73 is 17.15
to finish, you’ll just need to add 85.73 with 17.15 to get you answer,
the total cost of the meal is $102.9
brainliest? ..if you don’t mind
Answer:
$102.876 or $102.88

What is the Slope-Intercept Form of 16x + 4y = 44
Answer:
Y=-4x+11
Step-by-step explanation:
So first you gotta realize that slope intercept from is
y=mx+b
So you have the equation of
16x+4y=44 as the initial response
Now you just have to isolate it into the from of y=mx+b
SO first subtract 16x on both sides to isolate the 4y since its the initial response as y=mx+b
Then when that is done you should have the answer of
4y= 44-16x
Now You have to isolate the “y”.
By dividing 4 on both sides to get the new equation which will be
y= 11-4x
You can leave it like that or just move around the (x) to make it more plausible as the answer of y=mx+b
y= -4x+11
However you would put it, that is the answer
y= -4x+11
And
y= 11-4x
Matt is ordering basketball jerseys For his country's league. Last year he ordered 512 jerseys. 64 those jerseys were orange. If he ordered 600 jerseys this year, how many of them will be Orange if the ratio of orange jerseys to all the jerseys remain the same? Round to the nearest whole number.
Answer:
75
Step-by-step explanation:
Step 1
Matt is ordering basketball jerseys For his country's league. Last year he ordered 512 jerseys. 64 those jerseys were orange.
The ratio of all Jerseys to Jerseys that are Orange =
512 : 64
8 : 1
Step 2
If he ordered 600 jerseys this year, how many of them will be Orange if the ratio of orange jerseys to all the jerseys remain the same?
Since we are maintaining the ratio in step 1
Let the number of orange jerseys = x
600 : x = 8 : 1
Hence
600/x = 8/1
Cross Multiply
8 × x = 600 × 1
8x = 600
x = 600/8
x = 75
Therefore, this year, the number of orange jerseys = 75

Find the missing term(s) of the geometric sequence: 39, a2 , 975, ... Hint: r can be positive or negative.
9514 1404 393
Answer:
±195
Step-by-step explanation:
For some common ratio r, your missing term satisfies ...
39r = a2
a2·r = 975
So, ...
975 = 39r^2
25 = r^2
r = ±√25 = ±5
The missing term a2 = 39r could be either of 195 or -195.

Answer:
The volume of this figure is approximately 418.88 centimeters squared!
Step-by-step explanation:
The volume for a right circular cone is V = (π)(r^2)(h/3)
Substituting known values is as follows:
V = (π)(r^2)(h/3)
V = (π)(4^2)(25/3)
V = (π)(16)(25/3)
V ≈ 418.88 cm^3

Step-by-step explanation:
1. Formula for simple interest,
[tex]a = p(1 + rt)[/tex]
where
a = Final amount
p = Principal amount
r = annual interest rate
t = time in years
given p = 1250
r = 4.25/100 (r is a raw number, not percentage, so we need to divide 100 here to get the raw number)
t=4
Substitute values into formula to get a.
[tex]a = 1250(1 + (\frac{4.25}{100})(4)) \\ = 1250(1 + 0.17) \\ = 1250(1.17) \\ = 1462.50dollars[/tex]
Let's use the simple interest to calculate Henry's final amount first.
p = 5000
r = 4.2/100
t = 4
[tex]a = 5000(1 + ( \frac{4.2}{100} )(4)) \\ = 5000(1 + 0.168) \\ = 5000(1 .168) \\ = 5840 \: dollars[/tex]
To calculate the interest paid, just use the final amount minus the principal amount
[tex]a - p = 5840 - 5000 \\ = 840dollars[/tex]
Now we will do the exact same method for Ingrid.
p = 5,000
r = 3.9/100
t = 6
[tex]a = 5000(1 + ( \frac{3.9}{100} )(6)) \\ = 5000(1 + 0.234) \\ = 5000(1.234) \\ = 6170 \: dollars[/tex]
[tex]a - p = 6170 - 5000 \\ = 1170dollars[/tex]
Difference in interest between 2 of them =
Interest of Ingrid Loan - Interest of Henry Loan
= 1170 - 840
= $330

At Penny's Pie Shop, it costs $4 for
1
4
of a pie. What is the cost of a whole pie?
Simplify your answer and write it as a proper fraction, mixed number, or whole number.
Answer:
$16
Step-by-step explanation:
$4 for 1/4 of a pie, means that it isn't an entire pie. Luckily for us, this is simple multiplication. You would multiply like so:
4 x 4 = 16
And you'd get your answer, since 4/4 equals 1 whole.
