The high temperature for a day in January is 7°F the low temperature that day was "-5°F" what is the difference in temperatures
Answer:
The answer is 12
Step-by-step explanation:
first you count 1,2,3,4,5,6,7
after you do that when you go down to the negatives you are at -1,-2,-3,-4,-5 which is 5 numbers
so 7+5=12
given PR with P(-6, -6) and R(-2, 10), if Q lies on PR such that the ratio of PQ to PR is 5:8 find the coordinates of Q
Lines can be divided into segments using ratios. The coordinates of Q when PR is divided into 5:8 is [tex](-4.462,0.154)[/tex]
Given that:
[tex]P (x_1,y_1) = (-6,-6)[/tex]
[tex]R (x_2,y_2) = (-2,10)[/tex]
[tex]m:n = 5:8[/tex] --- the ratio
The coordinate of Q is calculated using the following line ratio formula
[tex]Q = \frac{1}{m+n}(mx_2 + nx_1,my_2 + ny_1)[/tex]
So, we have:
[tex]Q = \frac{1}{5+8}(5\times -2 + 8\times -6,5\times 10 + 8\times -6)[/tex]
[tex]Q = \frac{1}{5+8}(-58,2)[/tex]
[tex]Q = (-58/13,2/13)[/tex]
[tex]Q = (-4.462,0.154)[/tex]
Hence, the coordinates of Q is [tex](-4.462,0.154)[/tex]

a) Find the slope of the curve y= x^3 + 3 at the point P(-2, -5)
b) Find an equation of the tangent line to the curve at P(-2, -5)
9514 1404 393
Answer:
a) 12
b) y +5 = 12(x +2)
Step-by-step explanation:
The slope of a function is its derivative.
a) The slope of y = x^3 +3 at any point is y' = 3x^2. So, at the point where x=-2, the slope of the curve is ...
m = 3(-2)^2 = 12 . . . . slope at (-2, -5)
__
b) The equation of the tangent line is most easily written using the point-slope form of the equation of a line.
y -k = m(x -h) . . . . . line with slope m through point (h, k)
y +5 = 12(x +2) . . . . line with slope 12 through point (-2, -5)

Equations are used to show the relationship between variables (usually x and y). The true statement about f(x) is that the range of f(x) is [tex]y \ge -8[/tex]
Given that:
[tex]f(x) = 2(x - 2)^2 - 8[/tex]
To identify the true statement, I will make use of graphical method.
See attachment for the graph of [tex]f(x) = 2(x - 2)^2 - 8[/tex]
From the attached graph, we can see that the graph as a minimum at:
[tex](x,y) = (2,-8)[/tex]
And it opens upward.
This implies that the minimum y-value of f(x) is at -8, and it has no maximum.
In other words, the range of the function is:
[tex]f(x) \ge -8[/tex]
Hence, the true statement is option (a):
The range of f(x) is [tex]y \ge -8[/tex]

Answer:
n = 25
Step-by-step explanation:
The smallest perfect square larger than 144 = 12² is 169 = 13². As it happens, the difference of these squares is 25, a number divisible by 5.
So n=25 will make all of the expressions have values that are natural numbers.

Of the 121,301,000 men in the U.S., 3.38% didn’t complete 9th grade. How many men is this?
Answer:
4099973
Step-by-step explanation:
I hope this is correct! :)
Sorry if I'm wrong...
Approximately 4,100,938 men in the U.S. didn't complete 9th grade. To find out how many men in the U.S. didn't complete 9th grade, we can use the percentage given and calculate it as follows: Number of men who didn't complete 9th grade = (Percentage of men who didn't complete 9th grade / 100) * Total number of men in the U.S.
Given:
Percentage of men who didn't complete 9th grade = 3.38%
Total number of men in the U.S. = 121,301,000
Let's calculate:
Number of men who didn't complete 9th grade = (3.38 / 100) * 121,301,000
Number of men who didn't complete 9th grade ≈ 4,100,938
So, approximately 4,100,938 men in the U.S. didn't complete 9th grade.
