Answer:
v=± 47=±6.8557
Step-by-step explanation:
(1): "v2" was replaced by "v^2".
(2) Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation: v^2-(47)=0
The value of v is ± 6.856.
What is a perfect square ?A number when taken square root gives an integer is a perfect square and when a number is not a perfect square and we have taken it's square root the number is an irrational number.
According to the given question v² = 47.
∴ v = ±[tex]\sqrt{47}[/tex].
We know that v is between 6 and 7 but more closer to 7 as [tex]\sqrt{49}[/tex] is ±7 and [tex]\sqrt{36}[/tex] is ±6 we we can write an approximate value of v which is ±6.9 or we can use a calculator for which v = ± 6.856.

The lengths of salamanders have a normal distribution with mean 15cm, and standard deviation 2cm. In a collection of 300 salamanders, about how many have length greater than 16.8cm? (round answers to the nearest hundredth and show your work in the sketch area at left)
Answer:
55.22 salamanders
Step-by-step explanation:
Z score formula is given as:
Z score = x - μ/σ
x = 16.8 cm
μ = mean = 15cm
σ = standard deviation 2cm
Z score = 16.8 - 15/2
= = 0.9
Probability value from Z-Table:
P(x<16.8) = 0.81594
P(x>16.8) = 1 - P(x<16.8)
1 - 0.81594
= 0.18406
In a collection of 300 salamanders, about how many have length greater than 16.8cm?
= 300 × 0.18406
= 55.218 salamanders
Approximately to the nearest hundredth = 55.22 salamanders
Therefore, 55.22 salamanders have length greater than 16.8cm

The linear parent function,f(x)=x ,was transformed to create a graph g(x)=−f(x).
Which statement about the graph is true?
The graph of f is reflected over the x-axis to create the graph of g.
The graph of f is shifted 1 unit down to create the graph of g.
The graph of f is shifted 1 unit left to create the graph of g.
The graph of f is shifted 1 unit right to create the graph of g.
Answer:
The graph of f is shifted 1 unit down to create the graph of g.
Step-by-step explanation:
i took the test earlier and got this answer
The linear parent function f(x) = x is reflected over the x-axis to create the grap of g(x) = - f(x).
What is translation?There are four different kinds of translation: stretching, shrinking, rotating, and shifting.
When shifting, the entire graph is moved in the XY direction. When expanding and contracting a graph, we do so by a factor of k. When rotating a graph, we do so either clockwise or counterclockwise.
We know that when we change the sign of x in a function it is rotated about
the y-axis and when we change the sign of y in a function it is rotated about the x-axis.
f(x) = y = x and g(x) = - f(x) = - y.

If the equation of a line is y= - 2/3 x - 2 at what.point on the graph would I find the y- intercept?
Answer:
(0, -2)
Step-by-step explanation:
The slope equation is written as y = mx + b where m is the slope and b is the y-intercept. In this equation the slope, which is m, is -2/3 and the y-intercept is -2, which is the value of b. So the y-intercept on the graph would be found at point (0, -2)
Let y = mx +b, where m is the slope of the equation and b is the y-intercept.
So from the equation [tex]y=-\frac{2}{3}x-2[/tex] You'd find the y-intercept at (0,2). Alternative way, you can find the y-intercept by substituting x = 0 so -2x/3 will be 0 because x = 0 and -2x(0)/3 = 0-2 = -2.
So from the y = mx + b, you would find the y-intercept at (0,b)

The grocery store is selling 4 bags of bananas for $22.52. How much would it cost to buy 2 bags.
A. $22.52
B. $12.38
C. $11.26
D. $5.63
Please give me the steps if u know the answer
Answer:
the answer is c 11.26 just subtract from the actual number
First we must write down the information given
1. The store is selling 4 bags of bananas
2. 4 bags of bananas cost 22.52
3. We need to find the cost of 2 bags of bananas
If we know that 4 bags of bananas cost 22.52, and we know that we need 2 bags. We also know that 4 / 2 = 2
So, what we need to do is divide the cost of 4 bags by 2.
22.52 / 2 = 11.26
Which means, that the cost of 2 bags is C.

60+x-45+x=180
60-45+2x=180
15+2x=180
2x=180-15
2x=165

x=82.5
Answer:
x = 82.5
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180, that is
x + x - 45 + 60 = 180, that is
2x + 15 = 180 ( subtract 15 from both sides )
2x = 165 ( divide both sides by 2 )
x = 82.5

Xavier buys 4 snacks and
2 cans of soda. Each
snack costs $1.25, and
each can of soda costs s
dollars. Xavier's total for
the snacks and soda was
$8. How much did each
can of soda cost?
Answer: Each can of soda costed $1.50
Step-by-step explanation:
The total cost was $8
Xavier's bought 4 snacks; each $1.25
4 x 1.25 = $5
How much for 2 cans of soda?
Well we know how much the snacks were ($5) and the total cost was $8, so the 2 cans costed $3 because 5 + 3 = 8. But how much did each can cost? Each can costed $1.50 because if the 2 cans costed $3, and we wanted to know how much 2 costed, we would have to divide 3 by 2 which is 1.50. So each can costed $1.50
