Find the vertex
f(x) = 2x²-x-10
Answer:
vertex = (1/4 , -81/8)
Step-by-step explanation:
f(x) = y
f(x) = 2x²-x-10
a= 2
b= -1
c = -10
-b/2a
-(-1)/(2(2))
1/4
x = 1/4
f(x) = 2x²-x-10
y = 2x²-x-10
y = 2(1/4)²-(1/4)-10
y = 2/16-1/4-10
y = 2/16-4/16-160/16
y = -2/16-160/16
y = -162/16
y = -81/8

cos =

25
,
tan < 0
The exact values of the remaining trigonometric functions are sin(x) = -7/25 and tan(x)= -7/24
How to solve the trigonometric functions?The function is given as:
cos(x) = 24/25, tan(x) < 0
The sine function is calculated using:
sin^2(x) + cos^2(x) = 1
So, we have:
sin^2(x) + (24/25)^2 = 1
Collect like terms
sin^2(x) = -(24/25)^2 + 1
Evaluate the squares
sin^2(x) = -576/625 + 1
Take the LCM
sin^2(x) = (625-576)/625
Evaluate
sin^2(x) = 49/625
Take the square roots
sin(x) = -7/25 --- sin(x) is negative because tan(x) < 0
The tangent function is calculated using:
tan(x) = sin(x)/cos(x)
This gives
tan(x) = (-7/25) / (24/25)
Evaluate
tan(x)= -7/24
Hence, the exact values of the remaining trigonometric functions are sin(x) = -7/25 and tan(x)= -7/24

Three friends start a business and decide to split the profits equally. Susan invests $6,000, John invests $4,000, and Pria invests $7,000. If the profits are $12,000, how much of the profits would Pria receive if the profits were divided proportional to how much each friend invested
Susan investment = $6000
John investement = $4000
Pria investment = $12000
investment proportion of Susan, John and Pria = 6:4:12= 3:2:6
Hence, Pria share in profit = (6/11)*$12000
= $ 6,545.454
Answer:
Pria receives $4941.18 of the profits.
Step-by-step explanation:
• Susan invested $6,000,
• John invested $4000,
• Pria invested $7000.
The ratio of their investments Susan : John : Pria is 6000 : 4000 : 7000 ,
⇒ 6 : 4 : 7
This means that Pria should receive 7/17 th of the total profits.
∴ Pria receives = [tex]\frac{7}{17}[/tex] × $12,000

Micaela and Chelsea each improved their yards by planting rose bushes and ivy. They bought their supplies
from the same store. Micaela spent $58 on 5 rose bushes, r, and 3 pots of ivy, i. Chelsea spent $100 on 5
rose bushes and 10 pots of ivy. Write equations to represent the scenario. Then, find the cost of one rose
bush and the cost of one pot of ivy.
Answer: A rose bush, r, cost $8; one pot of ivy, i, cost $6;
Step-by-step explanation:
[tex]\left \{ {{5r + 3i =58} \atop {5r+10i=100}} \right.[/tex]
We combine them by minus, we get:
5r + 3i = 58
- 5r + 10i = 100
- 7i = - 42
i = 6
We plug in i = 6 to the first equation, we get:
5r + 3(6) = 58
5r + 18 = 58
5r = 40
r = 8
The cost of one rose bush is $8 and the cost of one pot of ivy is $6.
How to calculate the equationHere are the equations to represent the scenario:
Micaela: 5r + 3i = 58
Chelsea: 5r + 10i = 100
Let's solve the system of equations to find the cost of one rose bush (r) and one pot of ivy (i).
Subtracting the first equation from the second equation, we get:
7i = 42
Dividing both sides by 7 we get:
i = 6
The rose bushes will be:
5r + 3i = 58
5r + 18 = 58
5r = 58 - 18
5r = 40.
r = 8
This means that the cost of one rose bush is $8 and the cost of one pot of ivy is $6.
