Find
y
'
and then find the slope of the tangent line at
(
2
,
225
)
. Round the slope and y-intercept to 3 decimal place.

Answers

Since we are given the point, all we need to find is the slope to discover the tangent line.
To find the slope, you plug in 2 for y’ as it is the x-value of the point.

y’ = 2((2)^2+2(2)+7)(2(2)+2) = 180

Plug in the point and the slope in the point-slope formula

y - y1 = m(x - x1)

y - 225 = 180(x - 2)

Solve for y

y = 180x - 360 + 225

y = 180x - 135

Which inequality matches the graph?A)x > -2B)x < -2C)x = -2D)x ≤ -2

Answers

Answer:

the answer is D

Step-by-step explanation:

the answer is D because you know that the dot on the graph is filled in which means it has to be either _< or >_ and then because the line is pointing to the left of -2 so will the greater than or less than sign so X<_ -2 which means x can be anything less than or equal than -2.

Answers

Answer:

(- 11)

Answer b is correct

Step-by-step explanation:

To find this you can use

y = mx + c

Here,

m = slope

c = y - intercept

( -5, 4) = ( x ,y)

Let us solve now .

[tex]y = mx + c[/tex]

[tex]4 = - 3 \times - 5 + c \\ 4 = 15 + c \\ 4 - 15 = c \\ - 11 = c[/tex]

Therefore,

c = (-11)

That means y - intercept is ( -11 )

Answers

5+0.4+0.03+0.007 is the answer

The expanded form of the given decimal number is 5+0.4+0.03+0.007.

What is expanded from of a decimal number?

Unlike whole numbers, decimal numbers can also be written in the expanded form. For writing the decimals in expanded form, we multiply each of the decimal digits with increasing exponent values of (1/10).

The given decimal is 5.437

Now, the expanded form is

5+4/10+3/100+7/1000

= 5+0.4+0.03+0.007

Therefore, the expanded form of the decimal 5.437 is 5+0.4+0.03+0.007.

Answers

Answer:

f(2) = -3

Step-by-step explanation:

Given the graph of a negative-sloped function:

In order to determine the value of a function given that x = 2, simply locate the x-coordinate of 2 in the graph, and find its corresponding y-coodinate. Doing so will provide you the corresponding output value of y = -3. Therefore, the value of the function at x = 2 is f(x) = -3, or f(2) = -3.

Lynn put 3 7/8 gallons of gas in her gas tank. If there are now 18 1/6 gallons in the tank, how many gallons did she start with?
x - gallons she started with

Answers

Answer:

14.3 gallons      = 4 + 7.25/25  or 14.29 gallons.

Explanation:

18 1/6 gallons - 3 7/8 = 14.29

18 - 3 = 15

1/6 - 7/8 = 15 - 0.70833333333 = 14.2916666667

You need to be careful here if you use basic subtraction, simply as two minus would change to addition.

First change the mixed number of gallons into improper fractions.

3 7/8 ——> 31/8
18 1/6 ——> 109/6

Then find the LCM ( Lowest Common Multiple) in this case of the denominators it would be 24.

Convert both fractions as a factor of 24;

31/8 ——> 93/24
109/6 ——> 436/24

Then you want to take away the amount she was left with from how many she had added;

436 93 343
——— minus ——— = ———
24 24 24


As a mixed number this could be written

7
as 14 —-

What is mean by Percentage?

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

Given that;

Karl buys a discounted baseball bat that normally costs $347.25 using a coupon for a 35% disount.

Now,

Since, Karl buys a discounted baseball bat that normally costs $347.25 using a coupon for a 35% discount.

Hence, The discount price = 35% of $347.25

                                          = 35/100 × $347.25

                                          = $121.54

Thus, The sale price = $347.25 - $121.54

                                = $225.71
