Write the quadratic equation in standard form.
Answer:
2x² + 6x + 15 = 0
Step-by-step explanation:
Given quadratic equation is,
-2x² - 6x = 15
We have to convert this equation in the standard form of the quadratic equation,
ax² + bx + c = 0
(-2x² - 6x) = 15
-2x² - 6x - 15 = 0
2x² + 6x + 15 = 0

10x+18=8x+4 please and thank you
Answer:
x = -7
Step-by-step explanation:
10x + 18 = 8x + 4
take away 4 from both sides
10x + 14 = 8x
take away 10x from both sides
14 = -2x

An account earns simple interest. Find the annual interest rate. Interest = $60 principle = $500 time = 2 years Please help!!
Answer:
A = $560.00
Step-by-step explanation:
I = A - P = $60.00
Formula:
[tex]A = P(1 + rt)[/tex]
First, converting R percent to r a decimal
r = R/100 = 6%/100 = 0.06 per year.
Solving our equation:
A = 500(1 + (0.06 × 2)) = 560
A = $560.00
The total amount accrued on a principal of $500.00 at a rate of 6% per year for 2 years is $560.00.

Answer:
The answer is Exponential decay, 25% decrease
Step-by-step explanation:
In f(x) = 16(0.75)x the (0.75) does not have a 1 so it is decreasing and if it is only 75% of 16 then it would be losing 25% each time

Karen and Ricardo are 279 miles apart driving towards each on the same route. Karen drives at a speed of 59 miles per hour and Ricardo drives at a speed of 65 miles per hour. In how many hours will they meet?
Answer:
They will meet in 2.25 hours or 2 hours 15 minutes
Step-by-step explanation:
At any point in time;
distance = speed * time
Let the number of hours at which they meet be x
In x hours, the distance traveled by Karen will be 59 * x = 59x miles
In same x hours, the distance traveled by Ricardo will be 65 * x = 65x miles
Since they are traveling in opposite directions, the distance traveled at that time by Karen will be less than what Ricardo has traveled since he is traveling at a greater speed
However, the sum of whatever they have traveled will be equal to the distance between them
thus;
59x + 65x = 279
124x = 279
x = 279/124
x = 2.25 hours
?????????????????????????????????????????????????
Answer:
a) 0
b) -5
Step-by-step explanation:
We want to find f(x) = -4
This means find the value of x where y=-4
The value of x where y=-4 is x=0
Then find f(2)
This means find the value of y when x =2
The value of y when x=2 is -5

What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
We have,
Dave and 6 friends went to dinner.
Total amount of meal= $84

What is revenue?Revenue is the money generated from normal business operations, calculated as the average sales price times the number of units sold. It is the top line (or gross income) figure from which costs are subtracted to determine net income. Revenue is also known as sales on the income statement.
Total Revenue = Number of Units Sold X Cost Per Unit
According to the question
a> The company wants to reduce total expenses to $1,300.
Then expenses would i cut is from
Rent expenses as all other expenses are very important but we can try to lower out rent expenses by $1,300.
b>After the decision the impact will be on profit is
It will increase our profit by $1,300 as
Profit = Sales - Expenses
c>if the company increases prices 20%
i.e
If price will be increases then revenue will also increase by 20%
As Total Revenue = Number of Units Sold X Cost Per Unit
Therefore ,
Total Revenue = 356500 * 1.2
= 427800
d> If the cost of supplies (inputs) decreases,
The impact on profit is it will increase
as if cost of supplies decreases that is it will decrease the supplies expenses also which will cost in less expense and higher profit .
e> If the supply of a product goes down,
It will lower the revenue or sales also
as Total Revenue = Number of Units Sold X Cost Per Unit
But if supply of a product goes down and price per unit increase it will maintain the sales or revenue .

What is the inverse of the function g(x)=x^3/8+16?
The inverse of the function for [tex]g^{}(x) = \frac{x^{3} }{8}+16[/tex] is [tex]g^{-1}(x)=2\sqrt[3]{x-6}[/tex]
What is inverse of the function?"The inverse function of a function f (also called the inverse of f ) is a function that undoes the operation of f. The inverse of f exists if and only if f is bijective, and if it exists, is denoted by [tex]f^{-1}[/tex]."
We have
[tex]g^{}(x) = \frac{x^{3} }{8}+16[/tex]
Replace g(x) with y
[tex]y =[/tex] [tex]\frac{x^{3} }{8}+16[/tex]
Interchange the variables
[tex]x= \frac{y^{3} }{8}+16[/tex]
Rewrite the equation as
[tex]\frac{y^{3} }{8}+16= x[/tex]
⇒[tex]\frac{y^{3} }{8}= x-16[/tex]
Multiply both sides of the equation by 8
[tex]8.\frac{y^{3} }{8}=8(x-16)[/tex]

math question, evaluation
Answer:
P = 131 degrees
Step-by-step explanation:
We know that the sum of the interior angles of a triangle is 180 degrees
The exterior angles shown form a straight line with the corresponding interior angle
So the two interior angles can be calculated
The sum of two angles on a straight line is 180 degrees
By subtracting the exterior angles from 180, we can get the two interior angles which we can add to the angle at P to give 180
Thus;
P + (180-162) + (180-149) = 180
P + 18 + 31 = 180
P = 180-31-18
P = 131
A rectangular deck is 9 meters long by 7 meters wide. What is the length someone would walk
if they started at a corner and walked diagonally to the other corner?
Answer:
11.4 metres
Step-by-step explanation:
Use Pythagoras theorem for a right-angled triangle
a^2 + b^2 = c^2
if you cut the rectangle in half, it will become a right angled triangle.
a and b are two sides of the rectangle, while c is the diagonal or hypothenuse
so 9^2 + 7^2 = c^2
81 + 49 = c^2
c^ 2 = 130
square root 130 = c
you should get approximately 11.4 metres

Choose the function whose graph is given by:
O A. y= -0.5sin x
O B. y= cos X
Oc. y= 0.5cos x
OD. y= cos(2x)
(Ignore the answer selected I don’t know it it’s correct)
Using translation concepts, the function whose graph is plotted is given by:
y = 0.5cos(x).
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.
In this problem, the y-intercept is different of zero, hence it is a cosine function. The amplitude is of 0.5, hence the function is multiplied by 0.5, that is, y = 0.5cos(x), which means that option C is correct.

A. Survey all customers as they arrive at the store on a Monday.
B. Survey all customers who purchase shoes
C. Survey every 10th customer to enter the store.
D. Survey all customers who leave the store without making a purchase
Answer:
C
Step-by-step explanation:
This method is the best because it will survey the customers under one condition : every 10. If the store gets a lot of customers, then this should be easier to do. The rest are mostly dependent on what they do and that influences the survey. However, C makes it so that every 10 people are surveyed.
Answer:
A isnt the correct answer. B doesnt seem reasonable because its one specific item. D means they arent exactly a customer since they didnt buy anything therefore the answer would be C
