Answer:
Step-by-step explanation:
w = width
3w = three times the width
3w-7=7 feet less than three times the width
l = length = 3w-7
A=length × width (lw)
66 = (3w-7) × (w)
66 = 3w^2 - 7w
3w^2 - 7w -66 =0
factor
3 = 3 × 1 and 66 = 6 × 11,
6 × 3 = 18, 11 × 1 = 11, 18 - 11 = 7
(3w )(w )=0 so far
(3w )(w 6)=0 so far
(3w 11)(w 6)=0 so far
(3w+11)(w-6)=0
w-6=0
w=6
3w=3*6=18
3w-7=3*6-7=18-7=11
w=6 feet
l=11 feet
If g(3) = 5 and g(-1) = 5, explain why g(x) does not have an inverse.
g(x) cannot have an inverse because it gives the same output value for two individual input values.
In this case, g(x) is 5 when x is both 3 and -1. Hence, g(x) does not have an inverse.

Find the derivatives.
f ' (0) exists if the limit,
[tex]\displaystyle \lim_{h\to0}\frac{f(0+h)-f(0)}h[/tex]
exists, and f ' (0) has the value of this limit.
In order for this limit to exist, both limits from either side of h = 0 must exist.
Suppose h < 0. Then 0 + h is also negative, so by definition of f(x) we have
f (0 + h) = ((0 + h) + 1)² = h ² + 2h + 1
Then in the limit, if h is approaching 0, it must be from below or from the left:
[tex]\displaystyle \lim_{h\to0^-}\frac{f(0+h)-f(0)}{h} = \lim_{h\to0^-}\frac{(h^2+2h+1)-1}{h} = \lim_{h\to0^-}(h+2) = 2[/tex]
Now suppose h > 0, so that 0 + h is positive and h approaches 0 from above or from the right. Then
f (0 + h) = 2 (0 + h) + 1 = 2h + 1
and
[tex]\displaystyle \lim_{h\to0^+}\frac{f(0+h)-f(0)}h = \lim_{h\to0^+}\frac{(2h+1)-1}{h} = \lim_{h\to0^+}2 = 2[/tex]
Both one-sided limits match, so f ' (0) = 2.

100 points !!!!
Answer:
D
Step-by-step explanation:
The graph G(x) is moved to the left by 1.
So it would be G(x) = (x+1)^2
The equation of the blue graph is,
⇒ g (x) = (x + 1)²
What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given that;
The equation of the red graph is,
⇒ f (x) = (x)²
Since, The blue graph is shift 1 unit from red graph.
Hence, The equation of the blue graph is,
⇒ g (x) = (x + 1)²
Thus, The equation of the blue graph is,
⇒ g (x) = (x + 1)²

The diameter of Jupiter is about 1.4 x 10 5 kilometers. The diameter of Mars is snout 6.8 x 10 3 kilometers. About how many times greater is Jupiter’s diameter of Mars
Answer:
Jupiter's diameter is "about" 21 times greater than Mars with an exact answer of around 20.588
Step-by-step explanation:
Jupiter = 1.4 x [tex]10^{5}[/tex] = 140,000
(1.4 "plus 5 places" is how I think of it to make it easier)
Mars = 6.8 x 10³ = 6,800
To find how many times greater Jupiter is than Mars we can divide tje diameter of Jupiter by Mars:
140,000 / 6,800 = 20.588235 etc
I am not sure how far you are rounding, but Jupiter's diameter is "about" 21 times greater than Mars

There are 3 milliliters of compound A used for every 5 milliliters of compound B. If a chemist wants to make 408 milliliters of the drug, how many milliliters of compound A are needed?
Answer:
153
Step-by-step explanation:
The formula is 3 mL of A to 5 mL of B.
Let's say the chemist uses just the numbers in the formula.
Add 3 mL of A to 5 mL of B.
3 mL + 5 mL = 8 mL
The chemist ends up with 8 mL of the drug.
He really want 408 mL.
408 mL is how many times greater than 8 mL?
408/8 = 51
He needs to use 51 times the numbers in the formula.
51 * 3 mL of A + 51 * 5 mL of B =
= 153 mL of A + 255 mL of B
= 408 mL of the drug
Answer: 153

Find the value of x......
Answer:
100
Step-by-step explanation:
Since, line a is parallel to line t ( from diagram ).
x - 30 and 70 are alternate interior angles.
Reason : -
Alternate interior angles are equal when two lines are parallel and cut by a transversal line.
x - 30 = 70
x = 70 + 30
x = 100

What is the equation of this line?
y=3/4x+2
y=4/3x−2
y=3/4x−2
y=−3/4x−2
Answer:
y=3/4x-2
Step-by-step explanation:
Y-Intercept is -2 so it can't be the first option.
Then for the slope it goes up 3 and over 4. So the slope is 3/4.
So the equation is y=3/4x-2
In the diagram shown, C is the midpoint of BD. What is the
length of AC?
Set up an equation based on the given information, solve
for x, and plug answer back in to answer the question
Answer:
AC = 20
Step-by-step explanation:
C is the midpoint of BD.
That means that BC = CD
BC = x + 4
CD = 3x - 10
x + 4 = 3x - 10 Subtract x from both sides
4 = 3x - x - 10 Combine
4 = 2x - 10 Add 10 to both sides
4 + 10 = 2x - 10 + 10 Combine
14 = 2x Divide by 2
14/2 = 2x/2 Combine
7 = x
AC = AB + BC
AC = 2x - 5 + x + 4
AC = 3x - 1
AC = 3*7 - 1
AC = 21 - 1
AC = 20

Length of the hypotenuse of the right angled triangle (h) = 2.5 cm
Length of one of the side (a) = 1.5 cm
Let the length third side be 'b' cm
By Pythagoras theorem
h² = a² + b²
Adding Values on both sides
⇒ (2.5)² = (1.5)² + b²
⇒ 6.25 = 2.25 + b²
⇒ 6.25 - 2.25 = b²
⇒ 4 = b²
⇒ √4 = b
⇒ 2 = b
⇒ b = 2
