f(4) is 49
Explanation:
Given:
f(x) = 12x + 1
f(4) = ?
we have to substitute the value of x = 4 in the given equation.
f(4) = 12 X 4 + 1
f(4) = 49
Whenever there is such type of question then we have to just put the value of x in the equation. In case of f '(4) then we have to differentiate the given equation with respect to x first and then substitute the value of x in the differentiated equation.
Therefore, f(4) is 49

Step-by-step explanation:
Let
h(t) ---> the height of an object in meters
t ----> the time in seconds
we have
[tex]h(t)=-2.6t^2+40t+800[/tex]
For t=6 sec
substitute in the quadratic equation the value of t and solve for h

whats 5(3× + 4) - 3 (-2× +11)
Answer:
21x+53
Step-by-step explanation:
The simplified expression is 21x - 13.
To solve the expression 5(3x + 4) - 3(-2x + 11), follow these steps:
Distribute the 5 into the first set of parentheses:
5 × 3x = 15x
5 × 4 = 20
So, 5(3x + 4) becomes 15x + 20.
Distribute the -3 into the second set of parentheses:
-3 × -2x = 6x
-3 × 11 = -33
So, -3(-2x + 11) becomes 6x - 33.
Combine like terms:
(15x + 6x) + (20 - 33) = 21x - 13
The simplified form of the expression is 21x - 13.
The number of oranges a grocery store bought this year was 15% more than the number of oranges bought last year. This year the store bought 299 oranges. What was the original number of oranges purchased?
Answer:
The original number of oranges purchased is 260
Step-by-step explanation:
Let the original number of oranges purchased be x
We are given that The number of oranges a grocery store bought this year was 15% more than the number of oranges bought last year.
So, Oranges bought this year = [tex]x+15\%x=x+\frac{15}{100}x=1.15x[/tex]
We are given that This year the store bought 299 oranges.

The circumference C of a circle with radius r can be calculated using the formula
C=2πr. Which formula represents r in terms of C ?
A) r=2πC
B)r=C-2π
C)r=Cπ/2
D)r=C/2π
Answer:
D
Step-by-step explanation:
Given
C = 2πr ( isolate r by dividing both sides by 2π )
[tex]\frac{C}{2\pi }[/tex] = r → D
The circumference of a circle is defined as the distance around the circle.
The formula that represents r in terms of C is r = C/ 2π. The correct option is Option D
From the question, we are given the formula for the circumference of the circle C as :
C = 2πr
To represent in terms of C,
2πr = C
Divide both sides by 2π
2πr/2π = C/ 2π
r = C/ 2π
Therefore, the formula that represents r in terms of C is r = C/ 2π. The correct option is Option D

Question options:
(x+3)^2=2
(x−3)^2=2
(x+3)^2=16
(x−3)^2=16
Answer:
[tex] {(x + 3)}^{2} = 16[/tex]
Step-by-step explanation:
The given equation is
[tex] {x}^{2} + 6x - 7 = 0[/tex]
To find the equation that has the same solution, we complete the square.
Add the square of half the coefficient of x to both sides
[tex] {x}^{2} + 6x + {3}^{2} = {3}^{2} + 7 [/tex]
This becomes:
[tex] {x}^{2} + 6x + 9 = 9 + 7 [/tex]
Factor the first three terms to get a perfect square;
[tex]{(x + 3)}^{2} = 16[/tex]
The correct answer is C
The equation c. (x+3)^2=16 has the same solutions as the given equation x^2+6x−7=0.
Explanation:The equation that has the same solutions as the given equation x^2+6x−7=0 is c. (x+3)^2=16.
Step 1: Set the given equation equal to zero: x^2+6x−7=0.Step 2: Factor the equation. In this case, the equation does not factor easily, so we move on to step 3.Step 3: Use the quadratic formula: x = (-b ± √(b^2-4ac)) / (2a).Step 4: Substitute the values for a, b, and c from the given equation, we get x= 1 and x= -7.Step 5: Simplify the equation (x+3)^2=16. We get x = -3 + 4 = 1 and x = -3 - 4 = -7.Therefore, the equation (x+3)^2=16 has the same solutions as the given equation x^2+6x−7=0.

One number is 20 greater than another. If the lesser number is subtracted from three times the greater number, the difference is 84. Find the numbers.
Answer:
The numbers are 12 and 32.
Step-by-step explanation:
x = One number
x - 20 = Another number
3x - (x - 20) = 84 (If the lesser number is subtracted from three times the greater number, the difference is 84)
Let's solve for x, this way:
3x - (x - 20) = 84
3x - x + 20 = 84
2x = 84 - 20 (Subtracting 20 at both sides)
2x = 64
x = 64/2
x = 32 ⇒ x - 20 = 12
For the given problem, by denoting the lesser number as 'x', we can form and solve an algebraic equation to find 'x=12' and 'x+20=32', which are the lesser and the greater numbers respectively.
Explanation:This problem involves the concepts of algebraic equations. Let's denote the lesser number as 'x'. Therefore, the greater number becomes 'x+20' because it is 20 more than the lesser number. The problem states that three times the greater number subtracted by the lesser number is 84. So, we can translate that into the equation: 3*(x+20) - x = 84.
Solving this equation we get: 3x + 60 - x = 84, which simplifies further to 2x + 60 = 84. Deducting 60 from both sides gives 2x = 24. Finally, dividing by 2 gives x = 12 which is the lesser number. So the greater number becomes x + 20 = 12 + 20 = 32.

if the 3rd and 6th terms of an h.p are 5/16 and 1/5 then ,
the 10th term is
Answer:
The tenth term is
[tex] \frac{1}{20} [/tex]
Step-by-step explanation:
The 3rd term of an AP is 1/16.
This implies that:
[tex]a + 2d = \frac{5}{16} - - - (1)[/tex]
The 6th term of an AP is 1/5.
This means that:
[tex]a + 5d = \frac{1}{5} - - - (2)[/tex]
Subtract equation 1 from equation 2.
[tex]5d - 2d = \frac{1}{5} - \frac{5}{16} [/tex]
[tex]3d = - \frac{9}{80} \\ \implies \: d = - \frac{3}{80} [/tex]
From equation (1)
[tex]a + 2( - \frac{3}{80} )= \frac{5}{16} \\ a - \frac{3}{40} = \frac{5}{16} \\ a = \frac{5}{16} + \frac{3}{40} \\ a = \frac{31}{80} [/tex]
The tenth term is:
[tex]a + 9d = \frac{31}{80} + 9( - \frac{3}{80} ) \\ = \frac{31}{80} - \frac{27}{80} = \frac{4}{80} = \frac{1}{20} [/tex]

A rectangle has an area of 56 square inches and a perimeter of 36 inches.
Complete the table and write a system of equations to represent the length and width of the rectangle.
Answer:
Table #1:
Length (L) | Width (W) | Area (56)
Table #2:
Length (2L) | Width (2W) | Perimeter (36)
Equation #1: L · W = 56
Equation #2: 2L + 2W = 36
Step-by-step explanation:
The following are the formulas used to find the area and the perimeter of a rectangle:
Area = L · W
Perimeter = L + L + W + W
If you group common variables, you can simplify the formula used to find the perimeter down to:
Perimeter = L + L + W + W
Perimeter = 2L + 2W (Since you're adding 2 of each)
Using these formulas, we can insert our values into them. We know that the rectangle has an area of 56 square inches meaning:
L · W = 56
We know that the rectangle has a perimeter of 36 inches meaning:
2L + 2W = 36
Answer:
Table #1:
Length (L) | Width (W) | Area (56)
Table #2:
Length (2L) | Width (2W) | Perimeter (36)
Equation #1: L · W = 56
Equation #2: 2L + 2W = 36
