Step-by-step explanation:
a)solving for f(2)
f(2)= 5(2) - 3 (input the given value for the letter x)
f(2) = 10 -3 (multiply your inputed value with whatever is infront of it)
f(2) = 7 (Connect simmilar terms)
b) solving for f(32)
remember to follow the steps from above
f(32) = 5(32) - 3
f(32) = 160 -3
f(32) = 157
c) solving for f(-8)
we are going to end up on the negatives and thats okay. Not all answers have to be positive
f(-8) = 5(-8) -3
f(-8) = -40 -3
f(-8) = -43
The Blackbird Oil Company is considering the purchase of 20 new jumbo oil storage tanks. The standard model holds 12,000 gallons. Its
dimensions are the size of the similarly shaped jumbo model, that is, the ratio of the dimensions is 4:5.
a) How many gallons does one jumbo tank hold?
b) How many more gallons does one jumbo tank
hold than one standard tank?
c) If jumbo tanks cost 50% more than standard
tanks, which tank is a better buy?
Therefore , the solution of the given problem of ratio comes out to be 300,000.
A ratio is defined.A portion or fraction in mathematics displays how frequently one number is included in another. For instance, if there are eight orange and six lemons in a fruit plate, the proportion of oranges to lemonade is eight to six, or 8:6, which is comparable to the ratios 4:3 or the decimal 1.333.
Here,
We must use our grasp of proportionality to establish the maximum amount of shares that can be owned in this exercise.
The 20 huge variations will allow Blackbird Oil to store a total of 300,000 gallons.
The details in the assertion can be summed up as follows:
20 brand-new, sizable oil storage tanks.
The ratio is 4:5 for 12,000 gallons.
Because of the proportional ratio of 4.05, the enormous receptacles are 1.25 times larger than the ordinary ones, giving us:
=> 1200 * 1.25 = 15000
=> 15000 * 20 = 300000
As a result, the supplied problem's answer equals 300,000.

What is ellipse?
An ellipse in mathematics is a plane curve that has two focal points and is such that the sum of the two distances from any point on the curve to the focal points is a constant. It generalizes a circle, a special kind of ellipse in which the two focal points coincide.
Given:
The equation of ellipse is,
[tex]\frac{(x-2)^2}{81}+(\frac{(y+8)^2}{100}=1[/tex]
Since, the general form of ellipse is,
[tex]\frac{(x-h)^2}{a^2}+\frac{(y-k)^2}{b^2}=1[/tex]
where,
(h, k) is the center of ellipse
a is the minor axis
b is the major axis.
Here (h, k) = (2, -8) is the center of the ellipse.
9 is the minor axis and 10 is the major axis of the ellipse.
Also the graph of ellipse connects (2, 2), (11, -8), (2, -18) and (-7, -8) with smooth curve.
Hence, the center of the ellipse is (2, -8).
The endpoints of the major axis are 10 units from the center.
The endpoints of the minor axis are 9 units from the center.

What two rational expressions sum to 3x−2x2−x−12 ?
Enter your answer by filling in the boxes. Enter your answer so that each rational expression is in simplified form.
Answer and Explanation: To get the two terms on the right to combine into one term, we need the denominators of both terms to be the same. To do this we can plug in x+3 for the bottom left denominator and x-4 for the bottom right denominator. This makes both denominators (x+3)(x-4).
The numerators of both terms on the right just have to add up to 3x-2. One way we could do this is to the right one as 3x and the other as -2 or vice versa.
(x+3)(x-4) simplifies to x^2-x-12 which is why the denominator of the term on the left is that.
When you’ve finished solving an equation, it’s easy to check your work. Simply plug your answer for the variable into the original equation. Take, for example, the equation 4x + 9 = 45. After isolating the variable, you’ve come up with x = 9. To check your work, replace the x with 9: 4(9) + 9 = 45. Following the order of operations, multiply 4 by 9 first to get 36 + 9 = 45. Adding 36 plus 9 does equal 45, so you know you’ve found the right value for x. Which of these equations is correct when x = -2? A x + 8 = 5 B 3x - 1 = -10 C 2x - 7 = -11 D -95x = -190 BACK

Gabriel models the volume of a popcorn box as a right rectangular prism. Its dimensions are 2 1/2 in by 2 3/4 in by 5 in. If the box contains 26 cubic inches of popcorn, what percent is full? Round your answer to the nearest whole number if necessary. please really asap brainliest
To find the percent full of the popcorn box, we need to divide the volume of popcorn in the box by the total volume of the box, and then multiply by 100 to convert the result to a percentage.
First we need to find the total volume of the box:
V = l x w x h
V = (2 1/2 in x 2 3/4 in x 5 in) = (5/2 in x 7/4 in x 5 in) = (35/4 in^3) = 8.75 in^3
Now we can calculate the percent full:
percent = (26 in^3 / 8.75 in^3) x 100 = 2.97 x 100 = 297%
The popcorn box is 297% full.
It's worth noting that 297% means that the popcorn box is almost 3 times full

What is proportion?A proportion is an equation in which two ratios are set equal to each other. For example, if there is 1 boy and 3 girls you could write the ratio as: 1 : 4(for every one boy there are 3 girls) 1 / 4 are boys and 4 / 5 are girls. 0.20 are boys (by dividing 1 by 5). It can also be defined as the size, number, or amount of one thing or group as compared to the size, number, or amount of another.
The cost of 2.5kg of potatoes is £1.40
Therefore the cost of 1kg potatoe = 1.40/2.5 = £0.56
