Answer:

B. 28 inches

Step-by-step explanation:

We can use the Pythagorean theorem to solve this problem.

a^2 +b^2 =c^2  where a and b are the legs and c is the hypotenuse (diagonal)

16^2 + b^2 = 32^2

256 + b^2 =1024

Subtract 256 from each side

256-256 + b^2 =1024-256

b^2 = 768

Take the square root of each side

sqrt(b^2) = sqrt(768)

b = 27.7128129

Rounding to the nearest inche

b = 28 inches

Mel opened a savings account in April with an initial deposit of $250. Each month after April, Mel deposited an additional $60.
White raven [17]

Answer:

(y - 310) = 60(x - 1)

$670

Step-by-step explanation:

Mel opened a savings account in April with an initial deposit of $250. Each month after April, Mel deposited an additional $60.

If we express Mel's total deposit (y, in dollars) after x months since the month of April, then the slope of the linear function m will be 60 and (1, 250 + 60) = (1,310) is a point on the line graph.

Now, in point-slope form of a straight line equation gives if the slope of a straight line is m and (h,k) is a point on the line, then its equation can be written as (y - k) = m(x - h).

Now, in our case, the equation of the expression for Mel's total deposit will be given by

(y - 310) = 60(x - 1) ......... (1) (Answer)

Now, at the month of November, the x value will be 7, then from equation (1), Mel's total deposits through the month of November will be  

y - 310 = 60(7 - 1)

⇒ y = 310 + 360 = $670 (Answer)

Find the area of the parallelogram whose vertices are given below. ​A(negative 2​,2​) ​B(2​,0​) ​C(10​,3​) ​D(6​,5​)
swat32

Answer: Area of Parallelogram is 28 units squared.

Step-by-step explanation:

Knowing, any two vector sides of a parallelogram sharing the same initial point, we can find the area of parallelogram that two vectors are shaping, using the cross product of these two vectors a×b, where the area is given by

Area= |a×b| ___ (1)

From the given points,we may choose any three of them such and find a two vector and expresses the sides of parallelogram " or one side and a diagonal of parallelogram" ,we may choose for example B ,C and D.

Moreover, we may choose point B, to be common point for the two sides " the initial point of two vector" thus we need to find vector BD and vector BC .

Calculations are given in picture.
