Step-by-step explanation:

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

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.

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%

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.

Answer:

The first blank is 9  for 9 cucumbers

The second blank is 8 dollars

Step-by-step explanation:

We can use ratios to solve

3 cucumbers           x cucumbers

--------------------- = ----------------------

2 dollars                   6 dollars

Using cross products

3*6 = 2x

18 = 2x

Divide by 2

18/2 = 2x/2

9 =x

We need 9 cucumbers

For the third row

3 cucumbers           12 cucumbers

--------------------- = ----------------------

2 dollars                   y dollars

Using cross products

3*y = 2*12

3y = 24

Divide by 3

3y/3 = 24/3

y = 8

We need 8 dollars

Answer:

10c - 5

Step-by-step explanation:

" the product" tells you you're multiplying 10 and c, and "5 less" means subtracting 5 from the other part of the expression.

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]

Domain:(−∞,∞),{x|x∈R}

Range:[2,∞),{y|y≥2}

The Domain is {1, 2, 3, 4} and the range is { 11, 18, 27, 38}

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

Answer:

each tangent is 20.785 ft long

Step-by-step explanation:

since the tangent forms a right angle with the radius, and a line from P to O bisects the 60° angle:

tan 30° = 12/x

0.5774 = 12/x

0.5774x = 12

x = 20.785 ft

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 %
