Answer:
W = kq1q2 / r
Step-by-step explanation:
W varies jointly as the product of q1 and q2 and inversely as radius r
Product of q1 and q2 = q1q2
W = (k*q1"q2) / r
W = kq1q2 / r
Where,
W = work
q1 = particle 1
q2 = particle 2
r = radius
k = constant of proportionality
The answer is W = kq1q2 / r
Using proportions, it is found that the formula is:
[tex]W = k\frac{q_1q_2}{r}[/tex]
Work varies jointly as the charges, thus, the charges are in the numerator.Inversely as the radius, thus, the radius is in the denominator.There is a constant of proportionality k, which multiplies the fraction;Then, the formula is:
[tex]W = k\frac{q_1q_2}{r}[/tex]

When Isabel makes salad dressing, she likes to make it with 3 parts olive oil to 2 parts balsamic vinegar. If Isabel has 120 milliliters of olive oil (and a sufficient supply of balsamic vinegar), how many milliliters of salad dressing can she make? Thanks!
Let's say Olive oil = O, Balsamic Vinegar = B, Salad Dressing = S
For the salad dressing she uses 3 parts olive oil to 2 parts balsamic vinegar
So we can say for every 3 ml of olive oil, she needs 2ml of balsamic vinegar
We know she has 120ml of olive oil, so first step is to find how much balsamic vinegar she will be using.
Remember, for every 3 ml of Olive Oil, she needs 2ml of Balsamic Vinegar .
if you do 120 divided by 3 = 40
So she is making 40 times the amount of salad dressing.
This means you need to multiply the amount of balsamic vinegar by 40.
B = 40 times 2 = 80 ml
So now for the dressing we know :
She uses 120 ml of olive oil and 80 ml of balsamic vinegar.
So to find how many ml of salad dressing she can make, you just add the two.
S = O + B = 120 + 80 = 200 ml
Using proportions, it is found that she can make 80 milliliters of salad dressing.
This question is solved by proportions, using a rule of three.For 3 parts of olive oil, she uses 2 parts of balsamic vinegar. How many millilitres of vinegar when she has 120 millilitres of olive oil?The rule of three is:
3 parts of olive oil - 2 parts of balsamic vinegar.
120 ml - x ml
Applying cross multiplication:
[tex]3x = 2(120)[/tex]
[tex]3x = 240[/tex]
[tex]x = \frac{240}{3}[/tex]
[tex]x = 80[/tex]
She can make 80 milliliters of salad dressing.

if f(x)=7(x-1)+8, what is the value of f(1)
Answer:
8
Step-by-step explanation:
f(1)=7(1-1)+8
f(1)=7(0)+8
f(1)=0+8
f(1)=8
The value of f(1) if f(x)=7(x-1)+8 is 8
From the question,
The given function is f(x)=7(x-1)+8
We are to determine the value of f(1) if f(x)=7(x-1)+8
To do this, we will put the value x =1 into the function
That is,
f(x)=7(x-1)+8 becomes
f(1)=7(1-1)+8
The, we get
f(1) = 7(0) + 8
f(1) = 7×0 + 8
f(1) = 0 + 8
∴ f(1) = 8
Hence, the value of f(1) if f(x)=7(x-1)+8 is 8

Find the Perimeter of the figure below, composed of a parallelogram and one semicircle. Rounded to the nearest tenths place
Answer:
38.28
Step-by-step explanation:
ok so one of the sides don't count because the circle is there. so that leaves us with 14 + 14 + 4= 32(my bad)
then the circumference is for half the circle. and when finding the circumference you use radius so 2 cm. 2 x 3.14 x 2 = 12.56
then divide it by 2- 6.28
so that gives us 38.28

Perimeter of a triangle is 450 m and its sides are in the ratio 13 : 12 : 5. Find the area of the triangle and the altitude to the largest side.
Answer with steps .
Answer:
a = 195 m , b = 180 m , c = 75 m
Step-by-step explanation:
Let "a,b and c" be the sides of the triangle in the ration - 13:12:5
therefore , a:b:c = 13:12:5 => a = 13x , b = 12x , and c = 5x
therefore , Perimeter = 13x + 12x + 5x = 450
=> 30x = 450
=> x = 15
therefore , a = 13 x 15
b = 12 x 15 and
c = 5 x 15
hence , a = 195 m , b = 160 m and c = 75 m
