y = 7x + b
Because we need (5,8) to be an intersections, lets substitute these values in.
8 = 7(5) + b
8 = 35 + b
-27 = b
Now that we know the y-intercept, lets make our equation.
y = 7x - 27

For what value of the constant c is the function f continuous on (-infinity, infinity) for the equation f(x) = cx^2 + 2x if x < 2 and x^3 - cx if x> or = 2

c = 2/3
Answer is c = 2/3
To find the constant c that makes the given piecewise function continuous for all real numbers, the two parts of the piecewise function need to be equal at x = 2. By setting these two equal and solving for c, you will find the value that makes the function continuous.
Explanation:The question presents a piecewise function and asks for which value of the variable c does it become continuous for all real numbers. To make a function continuous at a certain point, both parts of the function must be equal at that point. In this case, the two parts meet at x = 2. We need to set the two parts equal to each other at x = 2 and then solve for c.
For the first part of the piecewise function,
[tex]f(x) = cx^2 + 2x[/tex], when we substitute x = 2, it becomes f(2) = 4c + 4.
For the second part of the piecewise function,
[tex]f(x) = x^3 - cx[/tex], substituting x = 2 again gives us f(2) = 8 - 2c.
In order for the function to be continuous, these two results must be equal. We set 4c + 4 = 8 - 2c and solve it for c. Solving this equation will provide the value of c for which the function is continuous for all x .

The sum of two complex numbers, where the real numbers do not equal zero, results in a sum of 22i. Which statement must be true about the complex numbers?

This a prove of that conclusion:
Let A + Xi be one complex number and B + Yi the other complex number, then:
A + Xi + B + Yi = 0 + 22i
=> A + B = 0 => A = -B, which means that the real part of one of the complex number is the opposite of the real part of other complex number. The imaginary part is not relevan for the question.

D: 64/343
Answers
Evaluate the exponents
4³= 64
7³= 343
Final answer: 64/343
Answer:
The correct option is D.
Step-by-step explanation:
The given expression is
[tex](\frac{4}{7})^3[/tex]
According to the property of exponent.
[tex](\frac{a}{b})^n=\frac{a^n}{b^n}[/tex]
Using this property the given expression can be written as
[tex](\frac{4}{7})^3=\frac{4^3}{7^3}[/tex]
[tex](\frac{4}{7})^3=\frac{64}{343}[/tex]
The simplified form of the given expression is [tex]\frac{64}{343}[/tex].
Therefore the correct option is D.
One fourth of a number q is 3 more than three times a number w. Solve for q.
Answers
q = 4(3w + 3)
q = 12w + 12 <===
To solve for q, multiply both sides of the equation 1/4q = 3 + 3w by 4. This eliminates the fraction and gives us q = 12 + 12w.
Explanation:To solve for q, we need to translate the given information into an equation. The problem states that one fourth of q is 3 more than three times a number w. Written as an equation, this is represented as:
1/4 q = 3 + 3w
To solve for q, we can multiply both sides of the equation by 4 to eliminate the fraction:
q = 12 + 12w
This gives us the solution for q in terms of w.

3/5 is the number which can be distributed across two terms inside parentheses
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given equation is 3/5 (x-10) = 18-4x-1
According to the distributive property, multiplying the sum of two or more addends by a number produces the same result as when each addend is multiplied individually by the number and the products are added together.
To solve the above equation we have to distribute 3/5 on LHS

The altitude of an equilateral triangle is 9 inches. Find the perimeter of the triangle in inches.
Answers
cos 30 = 9 /h where h = one of the sides of the equilateral triangle
h = 9 / cos 30 = 10.392 inches
Therefore the perimeter of the triangle = 3 * 10.392 = 31.1769 ins
Answer is 31.18 inches to the nearest hundredth.
The perimeter of the triangle will be 31.18 inches.
what is perimeter?The perimeter of a shape is defined as the total distance around the shape. It is the length of the outline or boundary of any two-dimensional geometric shape.
If we draw a perpendicular line from one of the vertices of the triangle we get 2 right angled triangles each with altitude 9 ins and vertex angle = 30 degrees. So:-
[tex]Cos 30 =\dfrac{ 9} {h}[/tex]
where h = one of the sides of the equilateral triangle
[tex]h = \dfrac{9 }{ cos 30} = 10.392 \ inches[/tex]

Note how y = -4(x-6)^2 + 3 is in the form y = a(x-h)^2 + k, which is vertex form. So we can see that the vertex is (h,k) = (6,3), since h = 6 and k = 3.
Note: This graph is an upside down parabola with (6,3) as the highest point.
---------------------------------------
In contrast, the max of g(x) is y = 6. This is the y coordinate of the highest point on the curve. One such point is (pi/2, 6). There are infinitely max points because the up and down pattern goes on forever.
So g(x) has the larger max compared to f(x).

A circle with a radius of inches has a central angle of 0.25 radians that intercepts an arc of inches.
Answers
= 0.25 * 4
= 1 inch
Answer:
Step-by-step explanation:
Given that there is a circle of .... inches with central angle 0.25 inches
by formula we have arc = radius *central angle in radians
The radii are given three options as 10,20,4 and corresponding arcs as
25,5, 16 inches.
By matching we find that 10(0.25) not equals 25
But 20(0.25) = 5 inches
Also 4(0.25) not equals 16 inches
Hence correct answer is radius = 20 and central arc = 5 inches
