Answer:
a) The acceleration between 20 and 40 seconds is equal to the slope in that range.
Remember that for aline that passes through the points (a, b) and (c, d) the slope is:
slope = (d - b)/(c - a)
In this case we can see the points:
(20s, 2m/s) and (40s, 4m/s)
Then the slope (and thus the acceleration) is:
slope = (4m/s - 2m/s)/(40s - 20s) = (2m/s/20s) = 0.1 m/s^2
The acceleration between 20 seconds and 40 seconds is 0.1 m/s^2
b) The total distance travelled is equal to the area under the curve.
So we could just count the number of squares, this is the easy way.
We can see that each square measures 10 seconds by 1 m/s, then the "area" of each square represents:
a = (10s)*(1m/s) = 10m
This means that each square represents a distance of 10 meters.
We can count that:
between 0s and 10s we have 1 whole square.
between 10s and 20s we have 2 whole squares.
between 20s and 30s we have 2 and half squares.
between 30s and 40s we have 3 and half squares.
Then the total number of squares under the curve is:
1 + 2 + 2.5 + 3.5 = 3 + 2.5 + 3.5 = 3 + 6 = 9
So we have 9 whole squares under the curve, and each square represents a distance of 10 meters, so the total distance traveled is:
Distance = 9*10m = 90m
c) We have an isosceles triangle where we know that one side measures 8.2 cm and another side measures 9.4cm
An isosceles triangle has two equal sides and one different.
So if we want to have the maximum perimeter, the two equal sides must have the longest side length (9.4 cm)
Then the (largest) perimeter of the triangle (the sum of the lengths of all 3 sides) is:
8.2cm + 9.4cm + 9.4cm = 27cm
Choose the solution to this inequality.
72≥b+95
Answer:
B. [tex]b \leq 1\frac{7}{10}[/tex]
Step-by-step explanation:
Isolate b in order to solve the inequality. Subtract [tex]\frac{9}{5}[/tex] on both sides of the inequality, then simplify. (You will need to convert the fractions in order to subtract and simplify further.)
[tex]\frac{7}{2} \geq b + \frac{9}{5} \\\frac{7}{2} -\frac{9}{5} \geq b + \frac{9}{5} -\frac{9}{5} \\\frac{35}{10} -\frac{18}{10}\geq b\\\frac{17}{10} \geq b\\1\frac{7}{10} \geq b[/tex]
Thus, [tex]b \leq 1\frac{7}{10}[/tex].

b

A weight of 6 lb stretches a spring a distance of 12 in. Find the constant k for the spring.
Answer:
Let F = the force (6 lbs) and x be the distance that the spring is stretched (12 inches).
F = kx
6 lb = k*(12 in.)
6/12 = k = 0.5 lb/in.
A weight of 6 lb stretches a spring a distance of 12 in. The constant k for the spring will be 0.5 lb/in.
How to obtain acceleration from force applied on an object?If the object is of mass m kg and force applied on it is of F N in the direction of motion, then the acceleration of that object is evaluated as:
a= F/m
Given; A weight of 6 lb stretches a spring a distance of 12 in.
Also,
Let F = the force and x be the distance that the spring is stretched
F = kx
6 lb = k*(12 in.)
6/12 = k = 0.5 lb/in.
Therefore, the constant k for the spring will be 0.5 lb/in.

Three runners in a relay race share the 8-mile distance equally. How many miles does each runner travel?
Answer: 2 2/3 miles
Step-by-step explanation:
From the question, we are informed that three runners in a relay race share the 8-mile distance equally.
The number of miles that each runner travel will be the total miles divided by number of runners. This will be:
= 8/3
= 2 2/3 miles

Given:
[tex]\Delta MAT\cong \Delta MHT[/tex] and [tex]m\angle 2=82^\circ[/tex].
To find:
Whether [tex]m\angle 1=47^\circ[/tex] is possible or not.
Solution:
We have,
[tex]\Delta MAT\cong \Delta MHT[/tex]
[tex]\angle AMT\cong \angle HMT[/tex] (CPCTC)
[tex]m\angle 3=m\angle 8[/tex] ...(i)
And,
[tex]m\angle 1=m\angle 8[/tex] ...(ii) (Vertically opposite angles)
From (i) and (ii), we get
[tex]m\angle 1=m\angle 3[/tex] ...(iii)
Now,
[tex]m\angle 1+m\angle 2+m\angle 3=180^\circ[/tex] (Linear pair)
[tex]m\angle 1+82^\circ+m\angle 1=180^\circ[/tex] (Using (iii))
[tex]2m\angle 1=180^\circ-82^\circ[/tex]
[tex]2m\angle 1=98^\circ[/tex]
Divide both sides by 2.
[tex]m\angle 1=\dfrac{98^\circ}{2}[/tex]
[tex]m\angle 1=49^\circ[/tex]
The measure of angle 1 is 49 degrees so it cannot be equal to 47 degrees.
Therefore, the required answer is "no", the given statement [tex]m\angle 1=47^\circ[/tex] is not possible.

Step-by-step explanation:
pretty sure you multiply the base times the height. But first you have to take out all triangwkes which leaves you with two of them.
so 8x4 for the top one and then 14x4.5 for the bottom one.
then for the triangles the one on the left is 5.6x4
the right one is 4.5x14
then divide both triangles answers into two. That should be the triangle areas. Then add the two triangles pieces together.
once don’t add the squares areas with the triangles and that’s THE AREAAAA

Which costs more per issue, 18-issue subscription for $40.50 or a 12-issue subscription for $33.60?
Answer:
12-issue subscription
Step-by-step explanation:
18-issue sub = $40.50 ÷ 18 = $2.25/issue
12-issue sub = $33.60 ÷ 12 = $2.8/tissue
=> The 12-issue subscription costs more per issue (2.8 > 2.25)
Answer:
so you would divide the cost by the issue
the 18 issue is $2.25 per issue
the 12 issue is $2.80 per issue
the 12 issue costs more

A boat which moves a 15 miles per hour without a current goes 36 miles upstream and 36 miles back in 5 hours. Find the speed of the current
Answer:
3 mph
Step-by-step explanation:
UPSTREAM:
distance = 36 miles ;
Speed = 15-c mph ;
TIME, t = distance / speed = 36/(15-c)
Downstream :
distance = 36 miles ;
speed = 15+c mph ;
time, t = 36/(15+c)
upstream time + downstream time = 5 hrs
36/(15-c) + 36/(15+c) = 5
36(15+c) + 36(15-c) = 5(15-c)(15+c)
1080 = 5(225 - c²)
1080 / 5 = 225 - c²
216 = 225 - c^2
216 - 225 = c²
-9 = c²
c = 3

What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
y = 4x +2 is an equation.
x + 2x + 3 = 4 is an equation.
We have,
y = 9x
The rate of change of this equation can be calculated by finding its differentiation.
Now,
y = 9x
Differentiating with respect to x we get,
dy/dx = 9dx/dx
dy/dx = 9
