Step-by-step explanation:
y = -3x² + mx + 10
dy/dx = -6x + m.
When dy/dx = 0, -6x + m = 0. => x = m/6.
We have y = -3(m/6)² + m(m/6) + 10 = 37.
=> -m²/12 + m²/6 = 27
=> -m² + 2m² = 324
=> m² = 324
=> m = 18 or m = -18.
What is the range of the function Rx) = 4x + 9, given the domain D = {-4, -2, 0, 2}?
A.
R= (-7, 1, 9, 17)
B.
R = {1, 7, 9, 17)
C.
R = (-17. -9,-1, 17)
D.
R= (-7, -1.9, 17)
Answer:
-7, 1, 9, 17
Step-by-step explanation:
F1=4*4+9=-16+9=-7F2=4*2+9=-8+9=1F3=4*0+9=0+9=9F4=4*2+9=8+9=17Prove or disprove that point (4.00, 4.50) lies on circle O centered at the origin.
Answer:
(4.0 , 4.5) to the center is not the distance of radius
Step-by-step explanation:
circle formula centered at origin: x² + y² = r²
x² + y² = 6² = 36
(4)² + (4.5)² = 16 + 20.25 = 36.25 ≠ 36

Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define Systems
3x - 2y = 0
4x + 2y = 14
Step 2: Solve for x
Elimination
Combine equations: 7x = 14Divide 7 on both sides: x = 2Step 3: Solve for y
Define equation: 3x - 2y = 0Substitute in x: 3(2) - 2y = 0Multiply: 6 - 2y = 0Isolate y term: -2y = -6Isolate y: y = 3What is an equation of the line that passes through the point (-1,-3)(−1,−3) and is perpendicular to the line x-2y=14x−2y=14?
Answer:
No Solution
Step-by-step explanation:
The equations given are:
x-2y=14
14x-2y=14
The only solution to this system is (0, -7) and therefore there is No Solution.

A pair of congruent angles are described as follows: One angle measures nine more than six times a number, and the other angles described as being thirty less than nine times a number. What is the measure of the angles in degrees?
Answer:
87 degrees
Step-by-step explanation:
congruent means equal to set each expression equal to each other:
9 + 6n = 9n - 30
39 = 3n
n = 13
substitute 13 into each expression; make sure they are both equal

In 2010, there were 12.4 million citizens of a certain country diagnosed with diabetes. This number of cases represents an increase of about 396% over the number of cases in 1973. How many cases of diabetes were there in 1973?
Answer:
3,131,313
Step-by-step explanation:
Let X represent the number of cases with diabetes in 1973.
An increase of 396% in diabetes cases in 1973 would be;
12.4 million = 396/100 × X
12.4 million = 396X/100
Cross multiply
12.4 million × 100 = 396X
X = [(12.4 million × 100) / 396]
X = 3,131,313
Therefore, the number of diabetes cases in 1973 is 3,131,313 cases

PLEASE HELP ASAP
Answer:
20%
Step-by-step explanation:
So, I would set this up as a proportion-
72 x
90 100
Cross multiply-
100 x 72 = 7200
Divide-
7200/90 = 80
Subtract-
100 - 80 = 20
So, it is a 20% decrease

Alex is a stockbroker. Earns % commission each week. Last week, sold $ worth of stocks. How much did he make last week in commission? If he averages that same amount each week, how much did he make in commission in 2011?
Answer:
a. $896
b. $46,592
Step-by-step explanation:
a. Alex earns 14% of the amount of stock he sells in a week.
The week before he sold $6,400. This means that his earnings in commission are:
= 14% * 6,400
= $896
b. Commission for the year:
If he makes $896 per week, there are 52 weeks in a year. Per year he would make:
= 896 * 52
= $46,592
