Answer:
y = -23f^2 + 1/2f + √3
Step-by-step explanation:
Standard form: y = ax^2 + bx + c
x = f
a = -23
b = 1/2
c = √3
–23f² + f/2 = -√3
-23f² + f/2 + √3 = 0
y = -23f^2 + f/2 + √3
y = -23f^2 + 1/2f + √3
the sum of four times a number and another number is 10. The difference of the two numbers is 35. What is the larger number? Also please explain how you got that answer
Answer:
The two numbers are 9 and -26.
The larger number is 9.
Step-by-step explanation:
Let the two unknown numbers be x and y.
The sum of a four times a number x and another number y is 10. Hence:
[tex]4x+y=10[/tex]
And the difference between the two numbers is 35. So:
[tex]x-y=35[/tex]
So, we have the system of equations:
[tex]\left\{ \begin{array} \ 4x+y=10 \\ x-y=35 \end{array}[/tex]
From the second equation, we can add y to both sides:
[tex]x=y+35[/tex]
Now, we can substitute this into the first equation:
[tex]4(y+35)+y=10[/tex]
Distribute:
[tex]4y+140+y=10[/tex]
Simplify:
[tex]5y+140=10[/tex]
Subtract 140 from both sides:
[tex]5y=-130[/tex]
Divide both sides by 5:
[tex]y=-26[/tex]
So, the value of y is -26 .
Then it follows that the value of x is:
[tex]x=y+35[/tex]
Substitute -26 for y:
[tex]x=-26+35=9[/tex]
So, our two numbers are 9 and -26.
The larger number is 9.
So, our answer is 9.

si se colocaron 16 postes para sostener 385.5m de cable telefonico, ? que distancia hay entre 2 postes?
Responder:
Los 48.1875m
Explicación paso a paso:
Si se colocaron 16 postes para soportar 385,5 m de cable telefónico, esto significa que la distancia entre los 16 postes es de 385,5 m.
Debemos encontrar la distancia entre 2 postes;
16 puestos = 385,5 m
2 puestos = x
Cruz multiplicar
16 veces = 2 * 385,5
16x = 771
x = 771/16
x = 48,1875 m
Por lo tanto, la distancia entre 2 postes es de 48,1875 m.

Given the preimage points: find the coordinates
of the dilated image using the scale factors. *look at picture*
Question 1)
Answer:
Please see the explanation.
Step-by-step explanation:
We know that the dilation of an original object shows how much bigger or smaller the image will really get, as compared to the original shape.
Also,
if the value of scale factor > 1, the image will get bigger.if the value of scale factor < 1, the image will get smaller.The new coordinates of the image can be determined by multiplying the scale factor with the coordinates of the original object.
Given the preimage points:
A(0, 5)B(4, 9)C(-1, -8)The formula of the dilation by a scale factor of 3:
(x, y) → (3x, 3y)
As the scale factor > 1, so the image will be bigger.Therefore, the coordinates of the dilated image after the dilation by a scale factor of 3 will be:
A(x, y) → (3x, 3y) = A(0, 5) → (3(0), 3(5)) = A'(0, 15)
B(x, y) → (3x, 3y) = B(4, 9) → (3(4), 3(9)) = B'(12, 27)
C(x, y) → (3x, 3y) = C(-1, -8) → (3(-1), 3(-8)) = C'(-3, -24)
Question 2)
Answer:
Please see the explanation.
Step-by-step explanation:
Given the preimage points:
A(0, 5)B(4, 9)C(-1, -8)The formula of the dilation by a scale factor of 1/2:
(x, y) → (1/2x, 1/2y)
As the scale factor < 1, so the image will be smaller.Therefore, the coordinates of the dilated image after the dilation by a scale factor of 1/2 will be:
A(x, y) → (3x, 3y) = A(0, 5) → (1/2(0), 1/2(5)) = A'(0, 5/2)
B(x, y) → (3x, 3y) = B(4, 9) → (1/2(4), 1/2(9)) = B'(2, 9/2)
C(x, y) → (3x, 3y) = C(-1, -8) → (1/2(-1), 1/2(-8)) = C'(-1/2, -4)

A girl had $6.50 while shopping at a local store. She bought 1 lb. of potatoes for $0.65 and wanted to spend the rest on tomatoes. Each pound of tomatoes costs $1.95. Which inequality models the pounds (n) of tomatoes she could buy?
Answer: 6.50-.65 > 1.95x
Step-by-step explanation:
Answer: 3 Ib
Explanation: 6.50 - 0.65 = 5.85 and 1.95 times 3 is 5.85 so she spends the rest of her money on 3 pounds of tomatoes.

Sara sold hotdogs and drinks at the soccer game.
18 hot dogs and 9 drinks sold for $45.00
20 hot dogs and 12 drinks sold for $52.00
What is the charge for an order of 4 hot dogs and 3 drinks?
Answer:
$11
Step-by-step explanation:
Set up the system of equations
18x + 9y = 45
20x + 12y = 52
Let's try to get y on one side for the first equation.
9y=45-18x
y=5-2x
Now substitute it into the second equation.
20x + 12(5-2x) = 52
20x + 60 - 24x = 52
-4x = -8
x = 2
Now solve for y using the first equation.
18(2) + 9y = 45
36 + 9y = 45
9y = 9
y = 1
Now that we know x and y we can solve for the price of 4 hot dogs and 3 drinks.
4(2) + 3(1) = z
8 + 3 = z
11 = z
That means that the price is 11 dollars.

(ANSWER FOR FREE BRAINPOINTS!) (FIRST TO ANSWER GETS BAINLIEST) The local park has a rectangular swimming pool that measures 40 yards in length and 15 yards in width. The community is planning to build a smaller swimming pool that is similar to the current pool. 40 yards, 15 yards, 24 yards. If the length of the new smaller pool will be 24 yards, what will be the width of the smaller pool in yards?
Answer:
9 yards
Step-by-step explanation:
Since both pools are similar, therefore the ratio of their length and width would be equal. That is:
Length of the current swimming pool : length of the new swimming pool = width of the current swimming pool : width of the new swimming pool
Thus, we can set up a proportion as shown below:
Let the width of the new swimming pool be x.
40 : 24 = 15 : x
[tex] \frac{40}{24} = \frac{15}{x} [/tex]
Cross multiply
[tex] 40*x = 15*24 [/tex]
[tex] 40x = 360 [/tex]
Divide both sides by 40
[tex] x = \frac{360}{40} [/tex]
[tex] x = 9 [/tex]
The width of the new swimming that is smaller would be 9 yards.

Can someone help me with this? During a certain period of time about 2000 penguins had an annual growth rate of 19% why will the population of penguins be after 5 years? This is exponential growth and decay
Answer:
Future amount of penguin = 4,772.70
Step-by-step explanation:
Given:
Current amount of penguin = 2,000
Growth rate r = 19% = 0.19
Number of year n = 5
Find:
Future amount of penguin
Computation:
Future amount of penguin = Current amount of penguin[1+r]ⁿ
Future amount of penguin = 2000[1+0.19]⁵
Future amount of penguin = 4,772.70
