Write an English phrase as an algebraic expression for the sum of 14 and a number, divided by 5.
Answer:
X/5 = 14
Step-by-step explanation:
We know that the sum will be what the answer of the algebraic equation. We know that the unknown number will be divided by 5. We should mark the unknown number with a variable. I personally used X. So we should write X divided by 5 equals 14.

For the function, find the point(s) on the graph at which the tangent line has slope 2.
y=-0.025x^2 +4x
If y = -0.025x^2 + 4x, then
y' = -0.05x + 4
Set y' = 2:
2 = -0.05x + 4
-2 = -0.05x
40 = x
Go back to y to find the point:
y = -0.025(40)^2 + 4(40) = 120
So the point (40, 120) on y = -0.025x^2 + 4x will have tangent line with a slope of 2.
A point lies to the left of the y-axis
and below the x-axis. What can you conclude about the coordinates
of the point
The point lie in quadrant 3 and both x and y coordinates of the point will be negative.
What are trigonometric identities?Trigonometric identities are the functions that include trigonometric functions such as sine, cosine, tangents, secant, and, cot.
It is given that point lies to the left of the y-axis and below the x-axis
For an example of a point in quadrant 3 and left of the y axis and below the x axis would be (-3,-3).
Therefore, the values of tangent and cotangent will be positive, while the values of sin, cosine, cosecant, and secant will be negative if trigonometric values of triangles are used in quadrant 3.
The point lie in quadrant 3 and both x and y coordinates of the point will be negative.

In 13 liters of 18% salty solution we add 402g of salt. What is the concentration of the new mixture?
9514 1404 393
Answer:
21.1%
Step-by-step explanation:
Adding 402 g of salt to a solution whose volume is 130 × 100 mL will increase the concentration by (402/130)%, or about 3.09%.
When the concentration of 18% has 3.09% added to it, the concentration of the new mixture is about 21.1%.
_____
Additional comment
We understand the units of concentration used here to be (1 g)/(100 mL) = 1%. These units are often used for a solution with a dissolved solid.

Answer:
C y > 2x/3 + 1
Step-by-step explanation:
Dashed line eliminates any equation option with "equal to" in it
y rises 4 units as x increases 6 units between the blue points so slope is 4/6 = 2/3
y intercept is 1
Shaded blue area is above the dashed line so "greater than" rules apply

Given: ΔABC, CM⊥AB, BC = 5, AB = 7, CA = 4√2
Find: CM
Step-by-step explanation:
first finding the area of the triangle by Heron's formula.
s=(a+b+c)/2, a=BC=5 unit, b=AC= 4√2unit, c=AB=7unit.
s=(5+4√2+7)/2 = (12+4√2)/2 =2( 6+2√2 )/2 = 6+2√2 unit .
Now, the Heron's formula : √s(s-a)(s-b)(s-c)
> √ (6+2√2)[(6+2√2)-5][(6+2√2)-4√2][(6+2√2)-7]
we have use √2's value ; 1.414 to simplify.
please simplify it with the help of calculator or doin it in a copy, because it is very difficult to share the full calculation. AFTER CALCULATION,
> √196.0000 > 14(units)².
Now, we know that the area of triangle is 14(units)². and another formula of finding the area of triangle is ½(base)(height). let the height be h.
Area = ½(base)(height)
=>14= ½(7)h. (after cross multiplication)
=>(14×2)/7=h. (after cancellation)
=>2×2=h.
=> 4units = h.
Therefore, CM that is the height is 4units.
I have every time written units because the unit is not given or you have not posted if given in the question you will write that unit only like cm or m anything like that.

A builder of tract homes reduced the price of a model by 15%. If the new price is $255,000, what was it's original price? How much can be saved by purchasing the model?
Answer:
Original=$300000
Saved=$45000
Step-by-step explanation:
100%/15%=85%
85%=255000
1%=255000÷85=3000
100%=3000x100=300000
