If 4(r + 2) – 13 = 11, what is the value of r?
Answer:
r = 4
Step by step explanation :
Step 1 : Add 13 to both sides.
4(r + 2) - 13 + 13 = 11 + 13
4(r + 2) = 24
Step 2 : Divide by 4 on both sides.
[tex]\frac{4(r+2)}{4} = \frac{24}{4}[/tex]
r + 2 = 6
Step 3 : Subtract 2 from both sides.
r = 4
The value of r is 4 in the given expression and this can be determined by using the arithmetic operation.
Given :
Expression - 4(r + 2) – 13 = 11
The following steps can be used to evaluate the given expression:
Step 1 - Write the expression.
4(r + 2) – 13 = 11
Step 2 - Add 13 on both sides in the above equation.
4(r + 2) – 13 + 13 = 11 + 13
4(r + 2) = 24
Step 3 - Multiply 4 by (r + 2) in the above expression.
4r + 8 = 24
Step 4 - Subtract 8 on both sides in the above expression.
4r + 8 - 8 = 24 - 8
4r = 16
Step 5 - Divide 4 on both sides in the above equation.
r = 4
The value of r is 4.

Right so, you would first graph your center point. Then, based on the radius, you would make four points. Let's say your center point is (0,0) and your radius is 2. You would make a point at (-2,0), (2,0), (0,-2), and (0,2). You would then draw a circle through those points. Let me know if you need any further clarification!

hence explain x²-8x+20 is always positive
Answer:
It is always positive because the discriminant is negative and therefore has no roots. This can also be interperted as the equation will always be above the x-axis on the parabola and therefore always be positive.
Step-by-step explanation:
The value of the quadratic expression (x - 4)² + 4 will be always positive.
What is the equation of the parabola?Let the point (h, k) be the vertex of the parabola and a be the leading coefficient. Then the equation of the parabola will be given as,
y = a(x - h)² + k
The quadratic expression is given below.
⇒ x² - 8x + 20
Convert the expression into a vertex form, then we have
⇒ x² - 8x + 16 + 4
⇒ (x² - 2 · x · 4 + 4²) + 4
⇒ (x - 4)² + 4
Thus, the value of the expression (x - 4)² + 4 will be always positive.

help! this is algebra 1 and idk how to do it lol
Answer:
a. x+6 = 0
b. y-2 = 0
Step-by-step explanation:
Given point is:
(-6,2)
a. Line perpendicular to x-axis:
A line perpendicular to x-axis means that the line is vertical and parallel to y-axis. Any equation parallel to y-axis has the form
x = k
where k is the x-coordinate of the point from which the line passes.
So the required equation is:
[tex]x = -6\\x+6 = 0[/tex]
b. Line perpendicular to y-axis:
A line perpendicular to y-axis will be a horizontal line parallel to x-axis having the equation of the form
y = b
where b is the y-intercept
Required equation is:
[tex]y = 2\\y-2=0[/tex]
Hence,
a. x+6 = 0
b. y-2 = 0

Answer:
1/4
Step-by-step explanation:
If you type cos(75)cos(15) into a scientific calculator, the answer comes out as 1/4.
The value of the trigonometric expression cos(75)cos(15) is 1/4 after applying the trigonometric identity.
What is trigonometry?Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.
We have a trigonometric expression:
= cos(75°)cos(15°)
As we know the trigonometric identity:
cos(a)cos(b) = (1/2)[cos(a + b) + cos(a - b)]
a = 75
b = 15
Plug the above values in the trigonometric identity:
cos(75)cos(15) = (1/2)[cos(75 + 15) + cos(75 - 15)]
cos(75)cos(15) = (1/2)[cos(90) + cos(60)]
The trigonometric ratio is the ratio of the pair of a right-angled triangle.
The value of cos90 = 0
cos60 = 1/2
cos(75)cos(15) = (1/2)[0 + 1/2]
cos(75)cos(15) = 1/4
Thus, the value of the trigonometric expression cos(75)cos(15) is 1/4 after applying the trigonometric identity.

Write a polynomial function f of least degree with the following zeros: 3, 4 + i
Answer:
[tex]f(x)=(x-3)(x^2-8x+17)[/tex]
Or:
[tex]f(x)=x^3-11x^2+41x-51[/tex]
Step-by-step explanation:
To find our factors, we can work backwards.
We know that 3 is a zero. This means that:
[tex]x=3[/tex]
Subtract 3 from both sides:
[tex](x-3)=0[/tex]
So, (x-3) is one of our factors.
We also know that (4+i) is a zero. So:
[tex]x=4+i[/tex]
First, let’s isolate the imaginary. So, subtract 4 from both sides:
[tex](x-4)=i[/tex]
Now, let’s square both sides:
[tex](x-4)^2=(i)^2[/tex]
Expand the left. Evaluate the right:
[tex](x^2-8x+16)=-1[/tex]
Add 1 to both sides. So, our factor is:
[tex](x^2-8x+17)=0[/tex]
Hence, our polynomial function is:
[tex]f(x)=(x-3)(x^2-8x+17)[/tex]
This is also the least degree since we did the most minimum we can do to solve backwards.
Further Notes:
If we want to convert this to standard form, we can distribute:
[tex]f(x)=(x^3-8x^2+17x)+(-3x^2+24x-51)[/tex]
Combining like terms will yield:
[tex]f(x)=x^3-11x^2+41x-51[/tex]
