Answer:
[tex]y-4=3(x-4)[/tex]
Step-by-step explanation:
Point-slope form is represented by the formula [tex]y-y_1 = m (x-x_1)[/tex]. Substitute the [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex] in the formula for real values in order to write the equation of a line in point-slope formula.
[tex]m[/tex] represents the slope, thus substitute 3 for it. [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point the line intersects. So, use the x and y values of the point (4,4) for the formula. Substitute 4 for [tex]x_1[/tex] and 4 for [tex]y_1[/tex]. This gives the following answer and equation in point-slope form:
[tex]y-4=3(x-4)[/tex]
∠A and \angle B∠B are supplementary angles. If m\angle A=(7x+24)^{\circ}∠A=(7x+24) ∘ and m\angle B=(7x-26)^{\circ}∠B=(7x−26) ∘ , then find the measure of \angle A∠A.
Answer:
115degrees
Step-by-step explanation:
Given the following angles
m<A=(7x+24)°
m<B=(7x-26)°
Since both angles are supplementary, their sum will be 180 degrees
Taking the sum of the angles
m<A + m<B = 180
7x+24 + 7x - 26 = 180
14x - 2 = 180
14x = 180+2
14x = 182
x = 182/14
x = 13
get m<A
m<A = 7x+24
m<A = 7(13) + 24
m<A = 91 + 24
m<A = 115
Hence the measure of angle m<A is 115degrees

Step-by-step explanation:
the diameter of a circle is 8 ft. Find the circumferenceto the nearest tenth.
Answer:
25.1 ft
Step-by-step explanation:
To solve for circumference is pretty simple. Just use the equation 2pi r (r=radius, radius is diameter divided by 2).
So essentially, apply to your calculator:
2(3.14)4=25.12
pretty simple! hope this helps!
are these lines parallel, perpendicular, or neither?
Answer:
[tex]\Huge\boxed{neither}[/tex]
Step-by-step explanation:
Parallel lines never touch and these lines intersect therefore these are not parallel lines
These lines may intersect but they do not create 90 degree angles which is essential for perpendicular lines and for those reasons the lines shown are not perpendicular lines
So we conclude that the lines shown are neither parallel lines nor perpendicular lines

What is the equation of the midline for the function f(x)? f(x)=1/2cos(x)+5
Answer: y=5
Step-by-step explanation:
At x = 0 and y = 5.5 the equation of the midline for the function
[tex]f(x)= \frac{1}{2} cos(x)+5[/tex] .
What is equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign. For example, 3x – 5 = 16 is an equation.
Is the cos graph symmetrical?
The function cos x is even, so its graph is symmetric about the y-axis.
According to the question
[tex]f(x)= \frac{1}{2} cos(x)+5[/tex]
as cos x is symmetric about y axis
So,
By plotting the graph
we can see that at point x = 0
y = 5.5 is the mid point of this equation
Hence, x = 0 and y = 5.5 the equation of the midline for the function
[tex]f(x)= \frac{1}{2} cos(x)+5[/tex] .

Jada has read 3/5 of a book. she has read 75 so far. how many pages are in the whole book?
Answer: Total number of pages is 125
Step-by-step explanation:
If 3/5 of a book is equal to 75, we can conquer that 1/5 of the book is 25 pages, because 75/3=25.
With this we can do 25 x 5 = 125 total pages.
