Answer:
0.46 newtons
Step-by-step explanation:
For these kinds of problems, you can employ the formula
[tex]E=\dfrac{F}{q}[/tex]
where E represents the field in N/C, F represents the force in newtons, and q represents the charge in coulombs. You can therefore set up the following equation:
[tex]1.4\times 10^4 N/C=\dfrac{F}{3.25\times 10^{-5}C} \\\\[/tex]
[tex]F=(1.4\times 10^4 N/C) \times (3.25 \times 10^{-5} C)=4.6 \times 10^{-1} N[/tex] (following sig figs)

A 40-question test has 108 possible points. There are m 4-point questions and n 2-point questions. How many of each type of questions are on the test?
Answer:
there are fourteen 4-point questions and twenty six 2-point questions.
Step-by-step explanation:
Given : A 40-question test has 108 possible points.
There are m 4-point questions and n 2-point questions.
So , equation for total number of questions in the test :
m + n = 40 | 4n + 2n = 108
Multiplying (i) by 2 , we get
2m + 2n = 80
Subtract (iii) from (ii) , we get
2m = 28
⇒ m = 28/ 2 = 14
Using value of m in (i) , we get
14 + n = 40 ⇒ n = 26
from this we get there are fourteen 4-point questions and twenty six 2-point questions.

On the map, one coordinate unit represents 100 feet. Her house is located at (8, 4) and the school entrance is located at (-4, -2). Each day, she walks directly from her house to the school entrance. To the nearest foot, what is the distance Kimmy walks to school each day?
Answer:
1342 feet
Step-by-step explanation:
Kimmy's house is located at (8, 4)
The school entrance is located at (-4, -2).
To find the distance Kimmy walks to school every day, we use the Distance formula:
[tex]\text{Distance =}\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Where [tex](x_1,y_1)=(8, 4),$ and (x_2,y_2)=(-4, -2).[/tex]
[tex]\text{Distance=}\sqrt{(-4-8)^2+(-2-4)^2}\\=\sqrt{(-12)^2+(-6)^2}\\=\sqrt{144+36}\\=\sqrt{180} \\=13.42$ Units\\Since 1 coordinate unit represents 100 feet.\\\\Distance walked by Kimmy to school every day\\=13.42*100 feet\\=1342 feet (to the nearest foot)[/tex]

Step-by-step explanation:
[tex]cos = \frac{adjacent}{hypotenuse}[/tex]
The hypotenuse of a right triangle is the angle that is opposite and not touching the 90 degree angle. In this case, the hypotenuse is 13.
The adjacent side is the side that is touching the angle but not the hypotenuse. That makes the adjacent side in this case 12.
That means that [tex]cos = \frac{12}{13}[/tex].

Brandon purchased a new guitar in 2012. The value of his guitar, t years after he bought it, can be modeled by the function A(t)=145(0.95)t.
Drag and drop the answer to the boxes below to complete the sentence.
145, 0.95
a decrease of, an increase of
5%, 45%, 95%
The rate of change in the value of the guitar is modeled by _____, which represents _____________ ______ per year.
Answer: The rate of change in the value of the guitar is modeled by 0.95, which represents a decrease of 5% per year.
Step-by-step explanation:
Hi, to answer this question we have to apply an exponential decay function:
A = P (1 - r) t
Where:
p = original price
r = decrease rate (decimal form)
t= years
A = price after t years
Replacing with the values given:
A(t)=145(0.95)t.
Where
0.95 = 1-r
0.95-1 = r
-0.05 =-r
0.05 =r
Converting to percentage form:
0.05 x 100 = 5%

What are the x-intercepts of y=4x^2-16
Answer:
(-2,0) and (2,0)
Step-by-step explanation:
To find the x intercepts of a graph, you need to set the y to 0. This is because a graph only intersects the x axis at the line y=0. Hence:
[tex]4x^2-16=0[/tex]
Factor:
[tex]4(x^2-4)=0 \\\\4(x-2)(x+2)=0 \\\\x=2,-2[/tex]
The x intercepts are at (-2,0) and (2,0). Hope this helps!
Answer:
The x intercepts are -2 and 2
Step-by-step explanation:
y=4x^2-16
Set equal to zero to find the x intercepts
0 =4x^2-16
Factor
0 = 4(x^2 -4)
Factor again, noticing the difference of squares ( a^2 - b^2) = (a-b)(a+b)
0 = 4(x-2) (x+2)
Using the zero product property
0 = x-2 0 = x+2
x =2 x = -2
The x intercepts are -2 and 2
If v varies directly as w, and v=24 when w=8, find the equation that relates v and w.
Answer:
v = 3w
Step-by-step explanation:
Given that
v ∝ w
The, v = k w ---------------(1)
Where k is the constant of proportionality
Now, v = 24, w = 8
Putting in (1)
24 = k(8)
Dividing both sides by 8, we get
k = 3
Putting k =3 in (1)
v = 3w
This is the required equation connecting both

What is the reference angle for a 240° angle? 30° 60° 180° 270°
Answer:
60°
Step-by-step explanation:
240° is between the two numbers 180°and 270°, So you're going to want to subtract 180 from 240 Thus, your answer will be 60!
hope you found this helpful :)
The reference angle is 60°. Option B
How to determine the angleSince 240° is in the third quadrant
Formula for reference angle in the third quadrant
Reference angle = ∝ - 180°
Reference = 240 - 180
Reference angle = 60°
Thus, the reference angle is 60°. Option B

Find the volume of the prism
pls!! show how you got the volume
Answer:
Step-by-step explanation:
The way you can solve this is by splitting the cube into two parts.
Split the top cube apart from the bottom cube and then find the volume of each and add them together.
The first cube on top would be 80x90x75= 540000 centimeters
The second cube would be 270x75x80=1620000 centimeters
540000+1620000=2160000 centimeters

What is the function of f(x)
Answer:
f(x) = 5/2x+7
Step-by-step explanation:
The y intercept is 7
We have 2 points (0,7) (2,12)
We can find the slope
m = (y2-y1)/(x2-x1)
= (12-7)/(2-0)
= 5/2
We can use slope intercept form
y = mx+b
y = 5/2x+7
f(x) = 5/2x+7

Step-by-step explanation:
Total surface area of all the lakes combined is 24.5×10¹⁰
What is the Total Surface Area?Total surface area refers to the area including the base(s) and the curved part. It is the total area covered by the surface of the object. If the shape has a curved surface and base, then the total area will be the sum of the two areas.
Given here; The surface area of the lakes and we are required to find The total surface area of all the lakes.
Thus we have TSA= (2.57 + 6.01+5.80+1.91+8.21)×10¹⁰
=24.5 ×10¹⁰
Hence, total surface area of all the lakes combined is 24.5×10¹⁰

At which root does the graph of f(x) = (x – 5)3(x + 2)2 touch the x-axis?
-5
-2
Ο Ο Ο Ο
2
5
Answer:
At x = -2 the graph of this polynomial will touch the x-axis.
Step-by-step explanation:
Recall the behavior difference between power functions of even and odd power. Odd powers are associated with the crossing of the x-axis, while even powers are associated with "touching" of the x axis.
in this cases, since they give you the function in factor form, the actual roots (x-values where the function adopts value zero) of the function are evident :
[tex]f(x)=(x-5)^3\, (x+2)^2[/tex]
It has a root at x = 5 [notice that at such x-value the factor (x-5) becomes zero], and this root is of multiplicity "3" (given by the power associated with the binomial factor for this root)
and has another root at x = -2 [notice that at such x-value the factor (x+2) becomes zero], and this root is of multiplicity "2" (given by the power associated with the binomial factor for it)
It is just the second root analyzed the one that shows an even power (2) associated to its binomial factor, and therefore it is at x= -2 that the graph of this function will show as "touching" the x axis.

Jade buys a blouse and a skirt for 3/4 of their original price. Jade pays a total of $31.50 for the two items. If the original price of the blouse is $18, what is the original price of the skirt?
Answer:
The skirt was originally 24 dollars
Step-by-step explanation:
3/4 ( b+s) = 31.50
where b is the original price of the blouse and s is the original price of the skirt
b = 18
3/4 ( 18+s) = 31.50
Multiply each side by 4/3
4/3 * 3/4 ( 18+s) = 31.50 *4/3
18+s =42
Subtract 18 from each side
18+s-18 = 42-18
s =24
The skirt was originally 24 dollars
