What is the area of the parallelogram?
A. 39.20 cm^2
B. 39.33 cm^2
C 56.58 cm^2
D. 78.66 cm^2
E. 93. 38 cm^2​

Answer:

C

Step-by-step explanation:

Using the rule of exponents

• [tex]b^{-m}[/tex] ⇔ [tex]\frac{1}{b^{m} }[/tex], thus

[tex]3^{-3}[/tex] = [tex]\frac{1}{3^{3} }[/tex] = [tex]\frac{1}{27}[/tex] → C

Answer: C 1/27

b^-3 and b=3

So we have 1/b^3= 1/3^3= 1/27

Answer:

[tex]18.4\ years[/tex]  

Step-by-step explanation:

we know that    

The compound interest formula is equal to  

[tex]A=P(1+\frac{r}{n})^{nt}[/tex]  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest  in decimal

t is Number of Time Periods  

n is the number of times interest is compounded per year

in this problem we have  

[tex]t=?\ years\\ P=\$2,000\\ r=0.06\\n=4\\A=\$6,000[/tex]  

substitute in the formula above  

[tex]\$6,000=\$2,000(1+\frac{0.06}{4})^{4t}[/tex]  

[tex]3=(1.015)^{4t}[/tex]  

Applying log both sides

[tex]log(3)=4tlog(1.015)[/tex]  

[tex]t=log(3)/[4log(1.015)][/tex]  

[tex]t=18.4\ years[/tex]

yes

Weight appears to be the independent variable, so will be graphed on the horizontal axis. Cost is the dependent variable, so will be graphed on the vertical axis.

The measure of PY is 24 centimeters, found using the properties of similar triangles and the correct option is C.

To solve this problem, we can use the following steps:

Identify the corresponding sides of the two similar triangles.

Write down the proportion for the corresponding sides of the two triangles.

Cross-multiply to solve for the unknown side.

In this case, the corresponding sides of the two triangles are:

AD = AP

DE = PR

EF = RY

We can write down the following proportion:

AD/DE = AP/PR

We know that AD = 6 cm and AP = 16 cm. We also know that PR = 8 cm. We can substitute these values into the proportion and solve for DE:

6/DE = 16/8

DE = 6 * 8 / 16

DE = 3 cm

Now that we know the length of DE, we can use the following proportion to solve for PY:

DE/EF = PR/PY

3/9 = 8/PY

PY = 8 * 9 / 3

PY = 24 cm

Therefore, the measure of PY is 24 centimeters.
So, the correct option is C.

You can alternatively apply PEMDAS as schools do today: Simplify everything inside the parentheses first, then exponents, then all multiplication and division from left to right in the order both operations appear, then all addition and subtraction from left to right in the order both operations appear.

Step-by-step explanation:

PEMDAS is an acronym for the words parenthesis, exponents, multiplication, division, addition, subtraction. Given two or more operations in a single expression, the order of the letters in PEMDAS tells you what to calculate first, second, third and so on, until the calculation is complete.

ANSWER

[tex] 10011_{2} \times 11_{2}= 111001_{2}[/tex]

EXPLANATION

We want to multiply:

[tex] 10011_{2} \times 11_{2}[/tex]

in base 2

One can choose to convert everything to base 10

This gives 19×3=57

We then convert 57 to base two to get

[tex]57 = 111001_{2}[/tex]

Or perform the multiplication in base 2 straight forward.

Answer: Option B

[tex](f + g)(x)=x^2 - x - 3[/tex]

Step-by-step explanation:

In this problem we have the function

[tex]f(x) = 2x - 1[/tex]

and the function

[tex]g(x) = x^2 - 3x - 2[/tex]

They ask us to perform the operation:

[tex](f + g)(x)[/tex]

Therefore we must perform the algebaic summa of the function f plus the function g

[tex](f + g)(x)=f(x) + g(x)[/tex]

[tex](f + g)(x)=2x - 1 + x^2 - 3x - 2[/tex]

Now we siplify the expression

[tex](f + g)(x)=x^2 - x - 3[/tex]

Answer:

a) T(3,0)

b) |CT|=2.83

c) |DT|=4.47

Step-by-step explanation:

The given parallelogram CARD has vertices (5, -2), (-1, -2), (1, 2), and (7, 2)

The diagonals of a parallelogram bisect each other.

Find the midpoint of one diagonal, that gives us the point of intersection of the diagonals T.

The midpoint of C(5,-2) and (1,2) is

[tex]T(\frac{5+1}{2},\frac{-2+2}{2}  )[/tex]

[tex]T(3,0)[/tex]

b) To find the length of CT, we use the distance formula; where C(5,-2) ahd T(3,0).

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

[tex]d=\sqrt{(3-5)^2+(-2-0)^2}[/tex]

[tex]d=\sqrt{4+4}[/tex]

[tex]d=\sqrt{8}[/tex]

[tex]d=2\sqrt{2}=2.83[/tex]

The length of CT is 2.83 to the nearest hundredth

c) To find the length of DT, we use the distance formula; where D(7,2) ahd T(3,0).

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

[tex]d=\sqrt{(3-7)^2+(2-0)^2}[/tex]

[tex]d=\sqrt{16+4}[/tex]

[tex]d=\sqrt{20}[/tex]

[tex]d=2\sqrt{5}=4.47[/tex]

The length of DT is 4.47 to the nearest hundredth

When you add 2+3 which equals 5 so it’ll be y=5x-7. And plug in y into the other equation. 5x-7-5x+8=0. -7-8=0, -7-8 =-1 therefore there is no solution because-7-8= -1 not 0.

Answer:

There are exactly 4 solutions

Step-by-step explanation

Given the two equation

y = x² + 3x – 7 ... (1)

y – 5x + 8 = 0 ...(2)

From equation 2,

y - 5x = -8

y = -8+5x ...(3)

Substituting equation 3 into 1

-8+5x = x²+3x-7

Moving -8+5x to the other side of the equation, we have:

x²+3x-7+8-5x = 0

x²+3x-8x-7+8= 0

x²-5x+1 = 0

Since the resulting equation is quadratic, we will get two solutions as our x and substituting both value of x in equation 2 to get y will give us two solutions for our y variable making a total of 4 solutions.

Therefore in the system of equation given, there are exactly 4 solutions

The number 0.009238 is expressed correctly to 3 significant figures as 0.00924

To express 0.009238 to 3 significant figures, we need to consider the first three non-zero digits from the left.

Identify the first three non-zero digits from the left: 9, 2, and 3.

Since the digit after the third significant figure (8) is greater than or equal to 5, we round up the last significant figure.

Therefore, the number rounded to 3 significant figures is 0.00924.

Answer:

Changing value of "d" changes the vertical shift of the cosine graph.

Step-by-step explanation:

Question says to find about how does your cosine graph change when including the d-value.

General equation of cosine function can be given as:

[tex]y=a\cdot\cos\left(bx-c)\right)+d[/tex]

In that formula, value of  "d" gives vertical shift.

So changing value of "d" changes the vertical shift of the cosine graph.

Answer:

y=2/3x+5/3

Step-by-step explanation:

The equation written in slope intercept form will be y = (2/3)x + 5/3.

When you know the slope of the line (m) to be investigated and the point of y-intercept (0,c) is also given, you utilize the slope intercept formula.

Slope intercept formula:

y = mx + c

m is the slope

c is the y intercept

Given equation in the question is

2x = 3y - 5

3y = 2x + 5

y = (2/3)x + (5/3)

Now if we compare this equation to slope intercept form we will get m = 2/3 and c = 5/3.

Hence the slope intercept form of the equation is y = (2/3)x + (5/3).

A)(x + 3)

B)(x - 2)

C)(x - 1)

D)(x + 6)

We know that area of rectangle = (length) x (width)

So basically we need to factor the given area of rectangle to find the corresponding dimensions.
