Answer:

The Y intercept doesn't exist, and the slope is undefined

Step-by-step explanation:

The graph provided for us is a vertical line. x= 7

this means the line will go up and down forever without a slant because x will always equal 7.

Ex:

X | Y

7  | -3

7  | -2

7  | -1

7  | 0

7  | 1

7  | 2

7  | 3

Find the area and perimeter of the shape below. Help plzzz.
kozerog [31]
Find the area of each shape and add.Let's start with the first semi-circle(half-circle)
If the area of a circle is πr² , then the area of a semi-circle is 1/2πr² where is 22/7 or 3.14, and r is the radius which is 1.8 meters
A=1/2πr²
A=1/2*22/7*1.8*1.8
A=5.09 m²(rounded to nearest hundredth)
Since the semi-circles are two and have the same radius, multiply the area of the first one by two or go through the same process again.
So 5.09 *2=10.18meters square is the area of the two semi-circles
Now, let's find the area of a rectangle  which is length times width, where length is 6 meters and width is (1.8+1.8, because 1.8 is half the width)=3.6 meters
A=l*w
A=6*3.6
A=21.6meters square
Therefore the area of the shape is 10.18m²+21.6m²=219.888m²

A curve has equation y=x√x.find the equation of the tangent to the curve at the point(1, 5)
rewona [7]

Answer:

y - 5 = \frac{3}{2}(x - 1)

Step-by-step explanation:

Note that \frac{dy}{dx} = m_{tangent}

Differentiate using the power rule

\frac{d}{dx}(ax^{n}) = nax^{n-1}

Given

y = x\sqrt{x} = x. x^{\frac{1}{2} } = x^{\frac{3}{2} }, then

\frac{dy}{dx} = \frac{3}{2}x^{\frac{1}{2} }

When x = 1

\frac{dy}{dx} = \frac{3}{2} . 1 = \frac{3}{2}

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = \frac{3}{2} and (a, b) = (1, 5), thus

y - 5 = \frac{3}{2}(x - 1) ← equation of tangent

Find the missing number. a. 3 : 24 = ___ : 72 b. ___ : 18 = 5 : 9 c. 6: ___ = 36 : 36
storchak [24]

Answer:

dividing both the numerator and denominator

a. 3 : 24 = 9 : 72

multiply by 3

b. 10 : 18 = 5 : 9

divide by 2

c. 6 : 6 = 36 : 36

multiply by 6
