Answer:
x^2 = 10
x = square root symbol with 10 underneath
Or x = 3.16227 (round to appropriate place)
—————
x^3 = 316
x = cubed root symbol with 316 underneath
or x = 6.81128 (round to appropriate place)
I answered them two different ways, because sometimes your teacher wants you to leave it under the square root or cube root symbol, when it can’t be solved to an exact integer.

lim(x --> 3)(-5x^ 2 -2x+4)
A. -47
B. 47
C. 0
D. 3
Hi there!
[tex] \large{lim_{x \longrightarrow 3}( - 5 {x}^{2} - 2x + 4)}[/tex]
Simply substitute x = 3 in the expression.
[tex] \large{ - 5 {(3)}^{2} - 2(3) + 4} \\ \large{ - 5(9) - 6 + 4} \\ \large{ - 45 - 6 + 4} \\ \large{ - 47}[/tex]
Questions can be asked through comment.
Furthermore, limit is like substituting a value. Note that limit is about an approaching value. This is a basic limit.
Hope this helps, and Happy Learning! :)
How many coins make $7.68 in cents
Find x. Round to the nearest tenth
A: 5.0
B: 7.8
C: 3.9
D: 4.6
Answer:
D
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos40° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{x}{6}[/tex] ( multiply both sides by 6 )
6 × cos40° = x , then
x ≈ 4.6 ( to 1 dec. place ) → D
Find the volume and surface area of a sphere with a radius of 6cm.
Find the area of the triangle
The area is __yd^2
Answer:
area of triangle = 4.5*6/2 = 13.5 sq.yd.
Step-by-step explanation:
The area of a right triangle is half of the product of the sides adjacent to the right angle.
Here the sides adjacent to the right angle are 6 yd and 4.5 yd.
Therefore the
area of triangle = 4.5*6/2 = 13.5 sq.yd.
Find the slope of the graph below. Help fast
Answer:
2x
Step-by-step explanation:
(5,5) is a point (I reckon it is from the screenshot you sent at least)
(0,-5) is a point
-5 - 5 = -10
0 - 5 = -5
-10/-5
Slope = 2x
Answer:
Two Possible Points:
5,5 and 6,7
7 - 5 2
____ = _____ = your slope is 2
6 - 5 1
When picking two points subtract the y(rise) from eachother first which will be your numerator and the x(run) from eachother in the same exact way you subtracted to the y which will be your denominator.

A pet store owner had her staff count the number of fish in each tank. Which interval has the fewest tanks?
What is 66.6% as a fraction ( simplest form )
the only solution to x² + bx + c = 0
is x = 5
work out the values of b and c
Answers:
b = -10
c = 25
=================================================
Explanation:
If x = 5 is the only solution then (x-5) is the only factor. Turns out we have repeated solutions and repeated factors. Meaning (x-5)(x-5) = (x-5)^2 is what we're after.
Expand that out to get
(x-5)^2
x^2 - 5x - 5x + 25
x^2 - 10x + 25
Then compare this to x^2 + bx + c to find
b = -10
c = 25
If you were to solve x^2-10x+25 = 0, you'll find that x = 5 is the only root.
calculate which number after an increase of 36%, is 170
Hello there I hope you are having a Great day, Percentage increase = 36% × 170 = 36 ÷ 100 × 170 = 36 × 170 ÷ 100 = 6,120 ÷ 100 = 61.2 So the Answer would be 61.2 Hopefully that helps you :)
PLEASE HELP ME I WILL HIVE BRAINLYEST
Answer:
Step-by-step explanation:
a). Points on a number line are,
x = -7, 1
Number of small blocks between x = -7 and 1 is 8.
Distance = 8
b). Difference between two points x = -7, 1 will be,
1 - (-7) = 1 + 7
= 8
-7 - 1 = -8
c). Absolute value of each difference,
|1 - (-7)| = 1 + 7
= 8
|-7 - 1| = |-8|
= 8
Use what you know about similarity and proportions to solve for x in the triangles below. Show all work.
4
10
5
x + 5
Answer:
Value of x = 7.5 unit
Length of side = 12.5 unit
Step-by-step explanation:
Given that both triangles are similar because all angles are equal;
So, the ratio of similar lines is in the same proportion.
[x + 5] / 5 = 10 / 4
4[x + 5] = 50
4x + 20 = 50
4x = 50 - 20
4x = 30
x = 30 / 4
x = 7.5
So,
Value of x = 7.5 unit
Length of side = x + 5
Length of side = 7.5 + 5
Length of side = 12.5 unit

Find missing measure (No.6)
Answer:
Step-by-step explanation:
6 no
1.angle 2=92 degree(being vertically opposite angle)
2.angle 1+33+92=180(sum of interior angles of a triangle)
angle 1+125=180
angle 1=180-125
angle 1=55
3.angle 3+angle 2+115+90=360(sum of four angles is always 360 degree)
angle 3+92+205=360
angle 3+297=360
angle 3=360-297
angle 3=63

Find the length of the arc.
Answer:
[tex]\frac{5\pi }{2}\:ft[/tex] (Option D)
Step-by-step explanation:
GIVEN :-
Angle subtended by the arc at center (θ) = 90°Radius of the circle = 5 ft.TO FIND :-
Length of the arcGENERAL FORMULAE TO BE USED IN THIS QUESTION :-
Lets say an arc subtends ∠θ at the center of the circle whose radius is 'r'.
[tex]=> Length \; of \; the \; arc = \theta \times \frac{\pi r}{180}[/tex]
SOLUTION :-
Length of the arc = [tex]\theta \times \frac{\pi r}{180} = 90 \times \frac{5\pi }{180} =\frac{5\pi }{2}[/tex]
If a movie begins at 5:10 p.m. and runs for 1 hour and 45 minutes, what time will the movie end?
(Answer:_:__p.m.)
Answer:
6:55 p.m
