(7TH GRADE LEVEL) Read the instructions and answer questions 16-18
Answer:
Equations
Step-by-step explanation:
16:
7 · (-3) = -21
-3 · 7 = -21
-21 ÷ 7 = -3
-21 ÷ (-3) = 7
17:
-4 · (-5) = 20
-5 · (-4) = 20
20 ÷ (-4) = -5
20 ÷ (-5) = -4
18:
1.5 · (-3) = -4.5
-3 · 1.5 = -4.5
-4.5 ÷ 1.5 = -3
-4.5 ÷ (-3) = 1.5
This is 7th grade?
Hope I helped :)
Answer:
16. 7 x -3= -21
-3 x 7= -21
-21/-3=7
-21/7=3
17. -4 x -5= 20
-5 x -4= 20
20/-4=-5
20/-5=-4
18. 1.5 x -3= -4.5
-3 x 1.5=-4.5
-4.5/-3=1.5
-4.5/1.5=-3

The following information is known about a savings account. Time = 6 years Interest rate = 1.9% Principal = $850 What amount of simple interest will be earned?
A. $16.15
B. $96.90
C. $946.90
D. $9,690.00
Answer:
I = PRT
T = 6
P = 850
I = 1.9% = 0.019
I = (850)(0.019)(6) = 96.90 <==

Use a graphing calculator to graph f(x) = x+cos(kx). Use calculus to determine which values of k lead to a function with no local maxima or minima. What conclusions can be drawn?
Answer:
Below, you can see the graph of the function:
f(x) = x + cos(k*x)
for different values of k, as follows:
red: k = 1
green: k = 2
orange: k = 0.
Now let's find the values of k such that our function does not have local maxima nor local minima.
First, remember that for a given function f(x), the local maxima or minima points are related to the zeros of the first derivate of f(x).
This means that if:
f'(x0) = 0.
Then x0 is a maxima, minima or an inflection point.
Then if a function is such that the f'(x) ≠ 0 , ∀x, then this function will not have local maxima nor minima.
Now we have:
f(x) = x + cos(k*x)
then:
f'(x) = 1 - k*sin(k*x)
This function will be zero when:
1 = k*sin(k*x)
1/k = sin(k*x)
now, remember that -1 ≤ sin(θ) ≤ 1
then if 1/k is smaller than -1, or larger than 1, we will not have zeros.
And this will happen if -1 < k < 1.
Find the slope of the line that passes through (10, 9) and (1, 1).
Simplify your answer and write it as a proper fraction, improper fraction, or integer.
Answer:
The slope of the line that passes through (10, 9) and (1, 1) will be:
[tex]m=\frac{8}{9}[/tex]Step-by-step explanation:
Given the points
(10, 9)(1, 1)The slope between (10, 9) and (1, 1) is given by
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(10,\:9\right),\:\left(x_2,\:y_2\right)=\left(1,\:1\right)[/tex]
[tex]m=\frac{1-9}{1-10}[/tex]
[tex]m=\frac{8}{9}[/tex]
Thus, the slope of the line that passes through (10, 9) and (1, 1) will be:
[tex]m=\frac{8}{9}[/tex]Solve for x. I really need help!

Find the slope of the line that passes through (-3, 2) and (6, 2).
Answer:
slope = 0
Step-by-step explanation:
(-3, 2) and (6, 2)
slope = (y1 - y2)/(x1 - x2)
remember, either x or y can be used but you have to be consistent
slope = (2-2)/(-3-6)
slope = 0/(-9)
slope = 0
Answer: no slope or 0
Step-by-step explanation:
The y-coordinates are the same for both points but the x coordinates are different. This signals a no-slope line, or a line where the slope is 0. Even if we apply the formula, which is [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], it still ends up with 0.

Dave bought 4 cookies at a bake sale if each cookie cost 0.85 and he paid with a twenty dollar bill how much change should he get back
Answer:
$16.60
Step-by-step explanation:
4 x 0.85 = $3.40
20 - 3.40 = 16.6
Dave should get back $16.60 in change.
Answer:
$16.6 dollars back
Step-by-step explanation:
The answer is $16.6 because 0.85 times 4 is 3.4 and 20 minus 3.4 is 16.6
a force of 10 newtons acts in a direction 75 above horizontal moving an object 15 meters from (0,0) to (15,0). What is the work done by the force?
a. 2.59 joules
b. 3.88 joules
c. 38.82 joules
d. 150.00 joules
Answer:
150 JoulesStep-by-step explanation:
Step one:
Given data
Force F= 10N
the distance is described by the coordinate = (0,0) to (15,0)
hence the distance = 15m in the x-direction.
Step two:
Required is the work done
we know that work done is expressed as
Wd= Force* Distance
Wd= 10*15
Wd= 150 Joules
Answer:
38.82

what is the measure of the angles in the triangle shown below.
Answer:
x = 35 degrees
Step-by-step explanation:
All angles in a triangle add up to 180 degrees.
Therefore, 48 + 97 + x = 180
Solve for x.
Thus, x = 180 - 48 - 97.
x = 35 degrees

factorise a³ - b³ + 4a-4b
Answer:
[tex]a^3-b^3+4a-4b:\:\left(a-b\right)\left(a^2+ab+b^2+4\right)[/tex]
Step-by-step explanation:
Given the expression
[tex]a^3-b^3+4a-4b[/tex]
solving the expression
[tex]a^3-b^3+4a-4b[/tex]
as
[tex]a^3-b^3[/tex][tex]\mathrm{Apply\:Difference\:of\:Cubes\:Formula:\:}x^3-y^3=\left(x-y\right)\left(x^2+xy+y^2\right)[/tex]
[tex]a^3-b^3=\left(a-b\right)\left(a^2+ab+b^2\right)[/tex]
also
[tex]4a-4b[/tex][tex]\mathrm{Factor\:out\:common\:term\:}4[/tex]
[tex]=4\left(a-b\right)[/tex]
so the expression becomes
[tex]=\left(a-b\right)\left(a^2+ab+b^2\right)+4\left(a-b\right)[/tex]
[tex]\mathrm{Factor\:out\:common\:term\:}\left(a-b\right)[/tex]
[tex]=\left(a-b\right)\left(a^2+ab+b^2+4\right)[/tex]
Therefore,
[tex]a^3-b^3+4a-4b:\:\left(a-b\right)\left(a^2+ab+b^2+4\right)[/tex]

A 9 kg log is being dragged along flat ground by a 120 N force at an angle of 45°. If
the log accelerates at a rate of 0.78 m/s2, what is the normal force acting on the log?
9514 1404 393
Answer:
3.347 N
Step-by-step explanation:
The vertical component of the dragging force is (120 N)/√2, so the net downward force is the difference between that due to gravity and the upward component of the dragging force.
(9.8 m/s²)(9 kg) -(120 N)/√2 = 3.347 N
The normal force acting on the log is 3.347 N.
