Answer:
a = -25
Step-by-step explanation: a+ 52/3 =9
multiply both sides by 3
3(a+52)/3 = 9.3
Simplify
a+52=27
Subtract 52 from both sides
a+52-52=27-52
Simplify
a= -25

Find the value of x in the triangle shown below 6 2
The value of x in the stated triangle is 6.32 based on given dimensions.
The stated triangle is right angled triangle and hence will follow Pythagoras theorem. The calculation will be done using the Pythagoras formula as stated -
Perpendicular² = Base² + Height²
Keep the values in formula to find the value of x
x² = 2² + 6²
Taking square on the Right Hand Side of the equation
x² = 4 + 36
Add the digits on Right Hand Side of the equation
x² = 40
x = ✓40
Taking square root
x = 6.32
Hence, the length of x is 6.32.

Step-by-step explanation:
2x²+8x-x-4
2x²+7x-4
Answer:
2x² + 7x - 4
Step-by-step explanation:
(2x + 1)(x + 4)
Each term in the second factor is multiplied by each term in the first factor, that is
2x(x + 4) - 1 (x + 4) ← distribute parenthesis
2x² + 8x - x - 4 ← collect like terms
= 2x² + 7x - 4
The price of a technology stock has risen to $9.82 today. Yesterday's price was $9.71. Find the percentage increase. Round your answer to the nearest tenth of a percent.
Answer:
9.71 ÷ 9.82 = .9987 or 1% .
The percentage increase is 1.1% to the nearest tenth
The calculation can be done as follows
Original price= $9.82
increase= $9.71
Change in price= 9.82-9.71
= 0.11
percent increase= 0.11/9.82 × 100
= 1.12
= 1.1 (to the nearest tenth)
Hence the percent increase is 1.1%

Y=x^2+4x+6 find the domain and range
Domain:(−∞,∞),{x|x∈R}
Range:[2,∞),{y|y≥2}
The Domain is {1, 2, 3, 4} and the range is { 11, 18, 27, 38}
What is Domain and Range?The range of values that we are permitted to enter into our function is known as the domain of a function. The x values for a function like f(x) make up this set. A function's range is the collection of values it can take as input. After we enter an x value, the function outputs this sequence of values.
Given:
Y=x^2+4x+6
As, we know that domain is the input value and range is the output value.
Then, x = 1
y = 1 + 4 +6
y= 11
and, x= 2
Y = 4 + 8 +6
Y = 18
and, x= 3
Y = 9 + 12 + 6
Y = 27
and, x = 4
Y = 16 + 16 + 6
Y = 38

which of the following best describes a cone
If f(x) = 2x^2 + 4x + 7, find f'(-5), using the definition of derivative. f'(-5) is the limit as x → -5
of the expression ?
The value of this limit is ?
Using the limit definition of the derivative, you have
[tex]\displaystyle f'(-5) = \lim_{x\to-5} \frac{f(x) - f(-5)}{x - (-5)} = \lim_{x\to-5} \frac{(2x^2+4x+7) - 37}{x + 5}[/tex]
Simplify the numerator:
(2x ² + 4x + 7) - 37 = 2x ² + 4x - 30
… = 2 (x ² + 2x - 15)
… = 2 (x + 5) (x - 3)
Then
[tex]\displaystyle f'(-5) = \lim_{x\to-5}\frac{2(x+5)(x-3)}{x+5} = \lim_{x\to-5} 2(x-3) = \boxed{-16}[/tex]
• • •
For your second question in the comments, if f(x) = -2x ² + 3x - 7, then by the definition of the derivative, you have
[tex]\displaystyle f'(x) = \lim_{h\to0}\frac{f(x+h)-f(x)}h = \lim_{h\to0}\frac{(-2(x+h)^2+3(x+h)-7) - (-2x^2 + 3x - 7)}h[/tex]
Simplify the numerator:
(-2 (x + h)² + 3 (x + h) - 7) - (-2x ² + 3x - 7)
… = (-2x ² - 4xh - 2h ² + 3x + 3h - 7) - (-2x ² + 3x - 7)
… = -4xh - 2h ² + 3h
Now compute the limit:
[tex]\displaystyle f'(x) = \lim_{h\to0}\frac{-4xh-2h^2+3h}h = \lim_{h\to0}(-4x-2h+3) = \boxed{-4x+3}[/tex]

Answer:
The owner will have to pay $ 125 after 2 hours.
Step-by-step explanation:
Given that the line graph shows the amount of water loss in a leaking tank during 7 hours, and the owner pays $ 1 for every 8 liters of water lost, to determine how much will he have to pay after 2 hours the following calculation must be performed :
((6000 - 5000) / 8) x 1 = X
(1000/8) x 1 = X
125 x 1 = X
125 = X
Therefore, the owner will have to pay $ 125 after 2 hours.

A survey was given to people who own a certain type of car. What percent of the people surveyed were completely satisfied with the car?
Answer:
65 percent
Step-by-step explanation:
The solution is 65 %
The percentage of people who were satisfied with the car is 65 %
What is Percentage?
A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the percentage of people who were satisfied with the car be = P
Now , the number of people who were satisfied with the car = 1625
The number of people who were somewhat satisfied with car = 665
The number of people who were not satisfied with the car = 210
The total number of people surveyed = number of people who were satisfied + number of people who were somewhat satisfied + number of people who were not satisfied
Substituting the values in the equation , we get
The total number of people surveyed = 1625 + 665 + 210
The total number of people surveyed = 2500 people
So , the percentage of people who were satisfied with car P = number of people who were satisfied with the car / total number of people surveyed
Substituting the values in the equation , we get
Percentage of people who were satisfied with car P = ( 1625 / 2500 ) x 100
Percentage of people who were satisfied with car P = 0.65 x 100
Percentage of people who were satisfied with car P = 65 %
Therefore , the value of P is 65 %
Hence , the percentage is 65 %

The number of bacteria in a certain population increases according to a continuous exponential growth model, with a growth rate parameter of 9.4% per hour.

Note: This is a continuous exponential growth model.
Do not round any intermediate computations, and round your answer to the nearest hundredth.
oo
E
Answer:
It takes 7.37 hours for the size of the sample to double.
Step-by-step explanation:
Continuous exponential growth model:
The continuous exponential growth model for populations is given by:
[tex]P(t) = P(0)e^{rt}[/tex]
In which P(0) is the initial population and r is the growth rate parameter, as a decimal.
Growth rate parameter of 9.4% per hour.
This means that [tex]r = 0.094[/tex]
So
[tex]P(t) = P(0)e^{rt}[/tex]
[tex]P(t) = P(0)e^{0.094t}[/tex]
How many hours does it take for the size of the sample to double?
This is t for which P(t) = 2P(0). So
[tex]P(t) = P(0)e^{0.094t}[/tex]
[tex]2P(0) = P(0)e^{0.094t}[/tex]
[tex]e^{0.094t} = 2[/tex]
[tex]\ln{e^{0.094t}} = \ln{2}[/tex]
[tex]0.094t = \ln{2}[/tex]
[tex]t = \frac{\ln{2}}{0.094}[/tex]
[tex]t = 7.37[/tex]
It takes 7.37 hours for the size of the sample to double.

If a line goes through the point (2, 7) and has a slope of -2, what is the equation of the line?
Answer:
y = -2x + 11
Step-by-step explanation:
Slope point equation:
y - y1 = m(x -x1)
y1 = 7 ; x1 = 7 , m = -2
y - 7 = -2(x - 2)
y - 7 = -2x -2*(-2)
y -7 = -2x + 4
y = -2x + 4 + 7
y = -2x + 11
