Soluton

y=-\frac{5}{4}x+\frac{11}{4}

A line perpendicular to another has a slope that is the negative reciprocal of the slope of the other line

The perpendicular slope will be

\frac{4}{5}

Now, given poin (0,7)

undefined

Find an expression for a rational function f(x) that satisfies the conditions: a slant asymptote of y = 2x, vertical asymptote a
lesantik [10]

Complete Question

The complete Question is attached below

Answer:

Option D

Step-by-step explanation:

From the question we are told that:

Slant asymptote of y = 2x

Vertical asymptote at x = 1,

Points (0,6)

Generally the Denominator  is give as

With

Vertical Asymptote at

x -1=0

Therefore

Denominator = (x-1)

Generally Slant asympote 2x Gives the Coefficient of the numerator

Therefore

The expression for a rational function f(x) that satisfies the conditions

F(x)=\frac{2x^2-2x-6}{x-1}

Option D

The area of the shaded section is 63 square units. What is the value of x ? Help
Juli2301 [7.4K]
I found an image that corresponds to the above question.
The shape was a rectangle. Its width is 7 units, its length is x.
The shaded area of the rectangle forms a trapezoid.

Area of a trapezoid = [(a+b)/2] * h

63 sq. units = (7+x)/2 * 7
63/7 = (7+x)/2
9 = (7+x)/2
9*2 = 7 + x
18 = 7 + x
18 - 7 = x
11 = x

The value of x is 11 units. It is the length of the rectangle.

Area of the trapezoid = (a+b)/2 * h
63 = (7+11)/2 * 7
63 = 18/2 * 7
63 = 9 * 7
63 = 63

PLEASE HELP i need it !!!!!
yan [13]

Answer:

Step-by-step explanation: Area of triangle is base x height divided by 2. So do 8 + 8 to get the base which is 16m. 16 x 8 = 128/2 = 64 m^2

Area of a 1/4 circle is PI Radius ^2 then divided by 4. So \pi*8^2 = 201.06/4 = 50.265 m^2

So to get the area of the entire figure you need to find the perimeter of the figure. So you should use the perimeter formula for each shape and then add all your perimeters of each shape. 1/4 Circle perimeter formula is C=2πr/4 . Perimeter of a square is P = 4a. Perimeter of a triangle is P =

a + b + c . Circle solving 50.27/4 = 12.5675 m^2. Triangle solving 8 + 8 + 16 = 32 m ^2 . Square solving 4 x 8 = 32 m ^ 2 .

This was so confusing and I dont know if this helps or not but I tried my hardest!
