Answer:

Rectangle

Step-by-step explanation:

Given : Deidre drew a quadrilateral with 4 right angles and opposite sides of the same length.

To find : Name all the kinds of polygons that could be Deidre's quadrilateral  ?

Solution :

Deidre drew a quadrilateral with 4 right angles and opposite sides of the same length.

Refer the attached figure below.

The right angles is at A,B,C ,D and

Opposite sides are equal  AC=BD and AB=CD

This polygon is a rectangle.

As rectangle is a quadrilateral with four right angles. Opposite sides are equal in length.

Suppose that F(x) = x^3 and G(x) = (4x)^3 − 5. Which statement best compares the graphs of F(x) and G(x)?
Rom4ik [11]
We have that
F(x) = x^3  and <span>G(x) = (4x)^3 − 5
so
</span>G(x) = F(4x) -5

the visual effect is
1) shrink horizontally by 1/4
2) shift down by 5

therefore 
the answer is the option
<span>D.The graph of G(x) is the graph of F(x) compressed horizontally and shifted 5 units down.</span>

How do you solve this absolute value equation and inequality problem?
blsea [12.9K]

Answer:

r < -7 or r > 10

Step-by-step explanation:

-2|3 - 2r| < -34

|3 - 2r| > 17      (Note the inequality sign flips because we divide by negative)

Now we split it up into 2 inequalities :-

3 - 2r > 17

-2r > 14

r  < -7     (answer)

and

3 - 2r < -17

-2r < -20

r > 10  (answer).

What is the value of p such that the line passing through (6,2) and (9,p) has a slope of -1?
Aleks [24]

Answer:

p= -1

Step-by-step explanation:

gradient=<u>y</u><u>²</u><u>-</u><u>y</u><u>¹</u>

<u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u>x²-x¹

-1 =<u>p</u><u>-</u><u>2</u>

<u> </u><u> </u><u> </u><u> </u><u> </u>9-6

-1=<u>p</u><u>-</u><u>2</u>

<u> </u><u> </u><u> </u><u> </u><u> </u> 3

multiply both sides by 3 to remove the denominators

-1×3=p-2

-3=p-2

put the like terms together

-3+2=p

-1=p

Evaluate the expression when x = 32 and y = 2. x4y WILL MARK BRAINLYNESS
NeTakaya

Answer:

Option d. 4

Step-by-step explanation:

The correct expression is \frac{x}{4y}

we know that

To find the value of the expression we will substitute the given value of x and y in the expression.

For x=32, y=2

substitute

\frac{32}{4(2)}=\frac{32}{8}=4

A study of the relationship between age and various visual functions (such as acuity and depth perception) reported the followin
maks197457 [2]

Answer:

(a) \sum x_i=56.68 and \sum x_i^2=197.46

(b) The sample variance is s^2=0.530 and the sample standard deviation is s=0.728

Step-by-step explanation:

(a)

The sum of these 17 sample observations is

\sum x_i=2.79\:+2.57+\:2.73\:+3.75\:+2.27+\:2.75+\:4.00+\:4.22+\:3.88+\:4.35+\:3.41+\:4.57+\:2.38+\:3.73\:+2.75+\:3.47+\:3.06\\\\\sum x_i=56.68

and the sum of their squares is

\sum x_i^2=2.79^2\:+2.57^2+\:2.73^2\:+3.75^2\:+2.27^2+\:2.75^2+\:4.00^2+\:4.22^2+\:3.88^2+\:4.35^2+\:3.41^2+\:4.57^2+\:2.38^2+\:3.73^2\:+2.75^2+\:3.47^2+\:3.06^2\\\\\sum x_i^2=197.46

(b)

The sample variance, denoted by s^2, is given by

s^2=\frac{S_{xx}}{n-1}

where S_{xx} =\sum x_i^2-\frac{(\sum x_i)^2}{n}

Applying the above formula we get that

S_{xx}=197.46-\frac{(56.68)^2}{17}\\\\S_{xx} =8.482

s^2=\frac{8.482}{17-1}=0.530

The sample standard deviation, denoted by <em>s</em>, is the (positive) square root of the variance:

s=\sqrt{s^2}

Applying the above formula we get that

s=\sqrt{0.530}=0.728
