Answer:
Step-by-step explanation:
1.
F=ma
89=68a
a=89/69 units/s²
2.F=ma
45=85 a
a=45/85=9/17 units/s²
Problem 1
Answer: Approximately 1.3 m/s^2
---------------
Work Shown:
We'll use the formula F = m*a, which is from Newton's second law.
The force applied is F = 89 newtons. The mass of the boulder is m = 69 kilograms. This means,
F = ma
89 = 69*a
a = 89/69
a = 1.28985507246377
a = 1.3
I rounded to 2 sig figs because the other given values (89 and 69) are to 2 sig figs as well.
=================================================
Problem 2
Answer: Approximately 0.53 m/s^2
---------------
Work Shown:
We'll follow the same idea as problem 1
This time we are given F = 45 and m = 85
So,
F = ma
45 = 85*a
85a = 45
a = 45/85
a = 0.52941176470589
a = 0.53
The acceleration is roughly 0.53 m/s^2, which means that for every second, the speed is increasing by roughly 0.53 m/s.

Answer:
You would need 16 pounds of apples!
Step-by-step explanation:
The table goes up by 3 for pounds of apples so you would do 10+3 which equals 13 and then add another three to get 16! Hope this helps.

When the positive integer m is divided by 6, the remainder is 5. What is the remainder when m+2 is divided by 6?
Answer:
The remainder is 1.
Step-by-step explanation:
First, you have to find the value of m. With the given information :
m ÷ 6 = 5
m = 5 × 6
m = 30 (no remainder)
if,
m = 30 + 5
m = 35 (with remainder as 5)
Next, you have to substitute m value into the expression, (m+2) ÷ 6 :
(35+2) ÷ 6
= 37 ÷ 6
= 6 1/6 (1 as a remainder)

What is the equation of the line that passes through the point (-5, -2) and has a
slope of -6/5
Answer:
Step-by-step explanation:
you are given the slope m = -6/5 and one point (x1,y1) as (-5,-2)
next use the point-slope formula [y-y1 = m(x-x1) ] and plug in the point and the slope
y-(-2) = -6/5(x-(-2)) ( they are making this tuff with all the minus signs :/ )
y+2 = -6/5(x+2) ( nice looks better, distribute the -6/5 )
y + 2 = -6/5x -12/5 (move the 2 over )
y = -6/5x - 12/5 -2 ( 2 = 10/5 )
y = -6/5x -12/5 - 10/5 (add the fractions )
y = -6/5x -22/5
that's in the form of the slope-intercept now [ y = mx + b ] so you're done :)
Describe the difference between slope and y-intercept
Answer:
The difference between slope and y-intercept, is y-intercept is a specific point. Y-intercept is when the line crosses the y-axis, or when x = 0. Slope is how much the y value changes when the x has changed +1, or -1, if that makes sense.

What is the equation for the graph shown below?
A. x^2 – 3x – 25
B. x^2 – 7x – 25
C. x^2 + 7x – 21
D. x^2 + 2x - 25
9514 1404 393
Answer:
D. x^2 + 2x - 25
Step-by-step explanation:
The y-intercept is -25, eliminating choice C. The axis of symmetry is negative, eliminating choices A and B. (The axis of symmetry is x = -b/(2a), so the coefficient of x must be positive for a negative axis of symmetry.)
The only viable choice is D:
x^2 + 2x - 25
_____
Additional comment
Though the y-intercept is in the right place, it seems to me the vertex and x-intercepts are slightly too far left for the given equation. That is why I chose to eliminate non-viable answers, rather than try to determine the equation directly. That is also why I elected to show a better graph of equation D.

What is the length segment of IL?
Answer:
IL = 11 cm
Step-by-step explanation:
Using the tangent ratio in right triangle IJL and exact value
tan45° = 1 , then
tan45° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{IL}{IJ}[/tex] = [tex]\frac{IL}{11}[/tex] = 1 , thus
IL = IJ = 11 cm
Answer:
11 cm
Step-by-step explanation:
Since m<IJL = 45 deg, and m<JIL = 90 deg, then m<ILJ is 45 deg.
That makes triangle IJL a 45-45-90 isosceles right triangle with congruent sides IJ and IL.
IL = IJ = 11 cm

We can see two main triangles from the image which are;
ΔVWX and ΔYZX
The two triangles are similar and using ratio of similar triangles, we have;
VW/WX = YZ/ZX
Plugging in the relevant values gives;
10/6 = YZ/3
Cross multiply to get;
YZ = 3 * 10/6
YZ = 5 miles
Since speed is given as 3.2 miles per hour and we know that formula for time is;
time = distance * speed
Then; time = 5 * 3.2
time = 16 hours
