The temperature is changing every day by negative 3 over 16 degrees Fahrenheit. What will be the change in the temperature after

4 days?

Answer:

"The temperature would be -\frac{3}{4} changed"

Step-by-step explanation:

Temperature is changing by  -\frac{3}{16} degrees F per day

So in 4 days, it will change:

4*(-\frac{3}{16})\\=-\frac{3}{4} degrees Fahrenheit

Hence, the temperature after 4 days would be 3/4th degree Fahrenheit lower.

Find the perimeter AND area of the parallelogram ABCD. Show all work
nexus9112 [7]

Since, this is parallelogram

so, opposite sides are equal

We will find value of sides

Calculation of AB:

we are given point A=(-2,3)

point B=(4,0)

we can use distance formula

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

now, we can plug values

AB=\sqrt{(4+2)^2+(3-0)^2}

AB=3\sqrt{5}

Since, this is parallelogram

so, opposite sides are equal

so,

CD=AB=3\sqrt{5}

Calculation of AD:

point A =(-2,3)

point D=(-5,2)

we can use distance formula

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

now, we can plug values

AD=\sqrt{(-5+2)^2+(2-3)^2}

AD=\sqrt{10}

Since, this is parallelogram

so, opposite sides are equal

so,

BC=AD=\sqrt{10}

Calculation of AE:

point A=(-2,3)

point E=(-3,1)

we can use distance formula

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

now, we can plug values

AE=\sqrt{(-3+2)^2+(1-3)^2}

AE=\sqrt{5}

(a)

we know that

perimeter of a parallelogram is sum of all sides

so,

perimeter is

=AB+BC+CD+DA

now, we can plug values

=3\sqrt{5}+\sqrt{10}+3\sqrt{5}+\sqrt{10}

=6\sqrt{5}+2\sqrt{10}...........Answer

(b)

we can use area of parallelogram formula

A=AE\times CD

we can plug values

A=\sqrt{5}\times 3\sqrt{5}

A=15............Answer

20 POINTS!! ASAP!!! PLEASE!! Use the figure to answer questions 1 and 2. In each diagram, line k is parallel to line l, and line
vaieri [72.5K]

Answer:

see the explanation

Step-by-step explanation:

we know that

<u><em>Alternate Exterior Angles</em></u> are created where a transversal crosses two lines.  Notice that the two alternate exterior angles are equal in measure if the two lines are parallel

In this problem

m\angle x=67^o ----> by alternate exterior angles

One way to verify alternate exterior angles is to see that they are the vertical angles of the alternate interior angles

What is the area of parallelogram ABCD?
professor190 [17]

Answer:

The formula for the area of a parallelogram is A=bh, if that was what you were asking.

Step-by-step explanation:

For example, the base is equal to 5 in. and the height is 6 in.

So, you plug in the numbers and should have A=5*6

Then, you multiply the two (5 times 6 equals 30)

And “A” (area) is equal to 30 in. sq.

30=5*6

The function d(t)=-2t^2+9t+18 most closely represents the height(h) of the golf ball in feet after t seconds. How long is the go
Kobotan [32]

Answer:

Step-by-step explanation:

d(t)=-2t^2+9t+18

calculate the derivate : f'(t) = - 4t+9

f'(t) = 0 : - 4t+9= 0   so t = 9/4

the maximum value is f(9/4) = ....... continue
