Please help it's for trig
Answer:
-4
Step-by-step explanation:
Given the expression
h(x) = -x^2 +4x
h(-2) = (-2)^2 + 4(-2)
h(-2) = 4 + (-8)
h(-2) = 4 - 8
h(2) = -4
Hence the value of the function when x = -2 is -4

7b-2/5 = 6b-7/5
Solve for b.
Answer:
b = -1
Step-by-step explanation:
here's your solution
=> 7b - 2/5 = 6b - 7/5
=> 7b - 6b = -7/5 + 2/5
=> b = (-7+2)/5
=> b = -5/5
= b = -1
hope it helps
Answer:
b = -1
Step-by-step explanation: I put all the like terms together by moving 6b and -2/5, which then changed their signs to negative and positive, respectively.
7b-2/5 = 6b-7/5
7b-6b = 2/5-7/5
b = -1

Question 1:
A trader made a profit of 20% on a radio which he sold for N144 .Calculate the cost price of the radio .
Question 2:
A motor dealer sold a car at a loss of 20% by selling it at N10,000 . Find the cost price.
Note :
Cost price formula :
[tex]C.P = S.P-P \\ or S.P+L[/tex]
Selling Price Formula :
[tex]S.P = C.P + P \\ or C.P - Loss[/tex]
Profit Percentage ( P% ) formula :
[tex] P \% = P/C.P × 100 \\ l \% = l/C.P × 100[/tex]
Answer:
Question 1
Given
SP = 144P = 20%CP = xUse formula and solve for x:
SP = CP + P144 = x + (20% of x)144 = x + 0.2x144 = 1.2xx = 144/1.2x = 120Cost price is N 120
Question 2
Given
SP = 1000P = -20% (negative because of loss)CP = xUse formula and solve for x:
SP = CP + P10000 = x - (20% of x)10000 = x - 0.2x10000 = 0.8xx = 10000/0.8x = 12500Cost is N 12500

Answer:
21.5sqft
Step-by-step explanation:
The area of the square is 10ft*10ft = 100sqft
The area of the circle is 5ft*5ft*pi = 25pi sqft
We're supposed to use 3.14 for pi, so the circle is around 25*3.14 sqft = 78.5sq ft
The area left over is 100sqft - 78.5sqft = 21.5sqft
Answer:

(divide by 2 because its a teiangle)
2nd shape is 10 x 8 = 80
3rd shape is 6 x 12 = 72
72 + 80 + 12 = 165mm

What is the fundamental principle of multiplication?Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
We are given that hot chocolate recipe calls for three teaspoons of cocoa for every cup of milk.
We need to find multiply 3 teaspoons by 3 cups to find the answer.
Therefore, we will use unitary method;
3 teaspoons x 3 cups = 9
Hence the answer is 9 teaspoons.

It takes Bobby 12 hours longer to build a robot than it takes Alex. Together, they can build the Robot in 8 hours. How long does it take Bobby to build the robot by himself?
Answer:
24 hours
Step-by-step explanation:
The computation of the number of hours taken by Bobby to build the robot by himself is shown below:
Given that
Bobby could take 12 hours
Together they could build in 8 hours
So based on the above information
the number of hours taken by Bobby to build the robot by himself is
Let us assume the above line be x
So,

A gemstone is cut in the shape of a triangular pyramid. The area of the base of the pyramid is 42 square millimeters. The height of the pyramid is 4 millimeters. What is the volume of the gemstone? (Recall the formula V = one-third B h.)
Answer:
the volume of the gemstone is 56 millimeters^3
Step-by-step explanation:
The computation of the volume of the gemstone is shown below:
As we know that
The volume of the triangular pyramid is
= (1 ÷ 3) × (base area) × h
Now put the given values to the above formula
= 1 ÷ 3 × 42 × 4
= 56 millimeters^3
Hence, the volume of the gemstone is 56 millimeters^3
The above formula should be used and the same should be considered
