The graph below have the same shape . What is the equation of the red graph ?
A. G(x) = (7-x)^2
B. G(x) = 1-x^2
C. G(x) = 7-x^2
D. G(x) = (1-x)^2
Answer:
Option B is correct .
Step-by-step explanation:
According to Question , both the graph have same shape . If we look at the the first graph it cuts x - axis at (0 , 2) and ( 0 , -2) . Hence x = 2 and -2 are the zeroes of the equation .
And ,the given function is ,
[tex]\implies f(x) = 4 - x^2 \\\\\implies f(x) = 4-x^2=0 \\\\\implies 2^2-x^2=0\\\\\implies (2-x)(2+x) = 0 \\\\\boxed{\red{\bf \implies x = 2 , (-2) }}[/tex]
• Hence ,we can can see that x = 2 and (-2) are the zeroes of graph.
This implies that if we know the zeroes , we can frame the Equation.
On looking at second parabola , it's clear that cuts x - axis at ( 1, 0 ) and (-1,0). So , 1 and -1 are the zeroes of the quadratic equation . Let the function be g(x) . Here , a and ß are the zeroes.
[tex] \begin{lgathered}\implies g(x) = (x-\alpha)(x-\beta) \\\\\implies g(x) = (1+x)(1-x) \\\\\boxed{\pink{\bf \implies g(x) = 1 - x^2}}\end{lgathered} [/tex]
Hence option B is correct .

Answer:
x = 3 ; y = 30
Step-by-step explanation:
Δ is equilateral or equiangular ⇒ m∠A = m∠B = m∠C = 60°
(2y)° = 60° ⇒ y = 30
(25x - 15)° = 60° ⇒ x = 3

Answer:
2 solutions
Step-by-step explanation:
Given the expression
2m/2m+3 - 2m/2m-3 = 1
Find the LCM of the expression at the left hand side:
2m(2m-3)-2m(2m+3)/(2m+3)(2m-3) = 1
open the bracket
4m²-6m-4m²-6m/(4m²-9) = 1
Cross multiply
4m²-6m-4m²-6m = 4m² - 9
-12m = 4m² - 9
4m² - 9+12m = 0
4m² +12m-9 = 0
Since the resulting equation is a quadratic equation, it will have 2 solutions since the degree of the equation is 2

The sales tax in a certain county is 7%. If an item marked at $19.94 is sold within the county, estimate the final cost of the item once tax is included.
Given:
Rate of sales tax = 7%
Marked price of an item = $19.94
To find:
The final cost of the item once tax is included.
Solution:
We have,
Rate of sales tax = 7%
Marked price of an item = $19.94
[tex]\text{Sales tax}=\dfrac{7}{100}\times 19.94[/tex]
[tex]\text{Sales tax}=1.3958[/tex]
Now, final cost of the item once tax is included is
[tex]\text{Final cost}=\text{Marked price}+\text{Sales tax}[/tex]
[tex]\text{Final cost}=19.94+1.3958[/tex]
[tex]\text{Final cost}=21.3358[/tex]
Therefore, the final cost of the item once tax is included is $21.3358.

Step-by-step explanation:
Car rideshare services are a popular option for people needing to move about in large cities. The scatterplot shows the distances of trips and fares, in dollars, for an adult living in a city over a period of a month. The value of r for the scatterplot is 0.950.
How would the value of the correlation coefficient change if the fares were plotted on the x-axis and distances on the y-axis?
The value of the correlation coefficient would be –0.950.
The value of the correlation coefficient would not change.
The value of the correlation coefficient would be closer to 0.
The value of the correlation coefficient would be closer to 1.
Answer:
The value of the correlation coefficient would not change.
Step-by-step explanation:
If the relationship between distance of trips and fares in dollars gives a correlation coefficient value of 0.950. This can be interpreted to mean that the relationship between both variables is strong and positive such that an increase in distance leads to corresponding increase in fares of the trip and vice versa. Thus, interchanging the axis upon which the variables are plotted would still tied the same correlation Coefficient value as the correlation coefficient does not depend on the axis upon which the variables are plotted.
Step-by-step explanation:
If its change it will not be right

Solve and state the correct answer for the trigonometric equation below
tan y = 6 - 4 cot y where
[tex] 0 \leqslant y \leqslant 360[/tex]
Answer:
y = {37.4°, 79.2°, 217.4°, 259.2°}Step-by-step explanation:
Given
tan y = 6 - 4 cot yWe now that
cot y = 1/tan ySubstitute tan y with x:
x = 6 - 4/xx² = 6x - 4x² - 6x + 4 = 0x² - 6x + 9 = 5(x - 3)² = 5x - 3 = ± √5x = 3 + √5x = 3 - √5Replace x with tan y:
tan y = 3 + √5 ⇒ y = arctan (3 + √5) ≈ 79.2° + 180°ktan y = 3 - √5 ⇒ y = arctan (3 - √5) ≈ 37.4° + 180°kAnswer is:
y = {37.4°, 79.2°, 217.4°, 259.2°}Discuss: a. The role of the expansion of 1/(1 - t) in powers of t in the explanation of the Basic Convergence Principle. b. The role of the Basic Convergence Principle in the explanation of the ratio test.
Answer:
See convergence analysis below
Step-by-step explanation:
For the expansion of 1/(1-t) in powers of t, we can recall that an infinite Geometric series with first term "1" and common ratio "t", in the case that the absolute value of "t" is smaller than 1, can be represented by:
[tex]\Sigma\limits^\infty_0\, t^n=\frac{1}{1-t} \\[/tex]
The condition for such, is that the absolute value of "t" is smaller than "1", which gives us the radius of convergence for this series "1" and the interval of convergence: - 1 < t < 1
Recall as well that using the geometric sequence [tex]1 + t + t^2 + t^3 +...[/tex]
The ratio test becomes [tex]\frac{a_{n+1}}{a_n} = t[/tex]
which is the SAME as the common ratio for the geometric sequence, and which in order to converge to the value [tex]\frac{1}{1-t}[/tex] requires that the absolute valu of the common ration be smaller than "1" rendering the same radius of convergence as discussed above.

sam drove 220 miles on 8 gallons of gas. find the unit rate.
Answer:
27.5
Step-by-step explanation:
Answer: I got 27.5
Step-by-step explanation:
This is a fraction equal to
220 miles ÷ 8 hours
We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 8
220 miles ÷ 8
8 hours ÷ 8
=
27.5 miles
1 hour
=
27.5 miles
hour
= 27.5 miles per hour

Given that y varies inversely with x, and y = 60 when x = 2, find x if y = 24
Step-by-step explanation:
xy = k, where k is a real constant.
When x = 2, y = 60.
=> (2)(60) = k, k = 120.
Hence when y = 24, x(24) = (120), x = 5.

If the length of a cube is 2cm then find the surface area of the cube?
Given:
Length of a cube is 2 cm
To Find:
Surface area of the cube
Solution:
A cube consists of 6 faces.
The area of each face = side x side
So, the total surface area of a cube = 6 x
side x side
Let a be the length of the given cube
: Surface area of a cube = 6a square
a = 2 cm (Given)
Surface area of cube = 6 x 22 =(6 x 4) = 24 cm square.
Hence, the surface area of the given
cube is 24cm square.

Each large roll of ribbon has 20yards. Each package takes 3 feet of ribbon. How many packages can be wrapped
Answer:
20
Step-by-step explanation:
20*3/3 = 20
The number of yards in 1 foot is 3 thus 20 packages can be wrapped.
What is unit conversion?To convert any unit into another is called a unit conversion.
In order to convert units, we need to care about their dimensions their dimension should not be changed.
As per the given,
Length of ribbon = 20 yards
Each package required = 3 feet
Since 1 yard = 3 feet so,
Each package required = 1 yard
The number of packages that can be wrapped = 20/1 = 20
Hence" The number of yards in 1 foot is 3 thus 20 packages can be wrapped".

Hellppp please!!! Find the area of the shaded region
Answer:
1600-400pi
Step-by-step explanation:
There are 2 semicircles making it a full circle. We are doing (40*40)-the area of the circle. We do 20*20 since that it is the radius and get 400. We then multiply it by pi. We get 400pi. Now we find the area of the square. This is 40*40 which gives us 1600. 1600-400pi is our answer
