Answer:
1: B. 2: 6n^6+9n^5+4n^2-4n. 3: D. 4: 6b^2-15b-9. 5: 48x^2-4x-4
Step-by-step explanation:
1.
A trinomial is a polynomial with three terms. The expression 7v^2 +2v +2 has 3 terms.
2.
A polynomial in standard form has its powers listed from highest power to lowest power. The terms are 6n^6, 4n^2, 9n^5, and -4n. Remove the bottom numbers to find 6, 2, 5, and 1. Next, put them in order. 6, 5, 3, 1. Then, re-add the bottom numbers. 6n^6+9n^5+4n^2-4n.
3. A sixth degree polynomial is one with a sixth degree power. So, the answer is either C or D. Next, let's look at the terms. The expression here has 4 terms. So, the answer is D.
4 and 5:
To solve expressions in this form, (a+b)(c+d), turn the expression into an equivalent one, ac+ad+bc+bd. Plug in the numbers (with a negative mark if its -a or a-b) into that expression to get your answer.
4 simplifies out into 6b^2+3b-18b-9, which can be simplified into 6b^2-15b-9
5 simplifies out into 48x^2+12x-16x-4, which can be simplified into 48x^2-4x-4.
HELP ASAP.
Questions are shown in the image, please include the procedure and explanation.
Answer:
1. 1) 1
2. 4) (-4,8)
3. 2) (2,-8)
4. (6, -4)
5. (4, 12)
6. (-8, 6)
7. (6, -4)
8. 2) (12,0)
9. 2) similar but not congruent.
10. (12, 24)
Step-by-step explanation:
An isometry preserves the orientation of a shape. In other words, nothing will change.
In dilations, a scale factor is how many times the preimage will be increased by. In other words, this is what you multiply the x and y-coordinates by.
For example, in question 4, the image has a dilation of 2.
[tex]3*2=6.[/tex]
[tex]-2*2=-4.[/tex]
(3, -2) ⇒ (6, -4).
If repetition of digits is allowed, how many different ways 5-digit codes are possible with the condition that the first digit should be a multiple of 3 and the last digit cannot be zero.
a. 17496.
b. 27000.
c. 18000.
d. 30000.
Answer:
b) 27,000
Step-by-step explanation:
3 × 10 × 10 × 10 × 9 = 27000
'3' because the first digit can only be 3,6, or 9
'9' because the last digit cannot be zero, leaving only 9 options

Answer:
15^18/(15^3)=15^15
Step-by-step explanation:
rule for quotients of similar bases with different exponents is:
(a^c)/(a^b)=a^(c-b)
15^18/(15^3)=15^15

What is the range of function g?
g(x) = /x-1+2
A. y > 1
B. y > 2
C. y <2
D. y <1
Answer:
Option B
Step-by-step explanation:
Equation of the function is,
[tex]g(x)=\sqrt{x-1}+2[/tex]
Parent function of the given function 'g' is,
[tex]h(x)=\sqrt{x}[/tex]
By translating the parent function 'h' n=by 1 unit horizontally left and 2 units upwards we get the function 'g'.
That means function 'g' starts from a point (1, 2).
Range of the function 'g' will be all the values of y ≥ 2.
Option B is the answer.
Answer:
Range of the function 'g' will be all the values of y ≥ 2.

Help me fast 50 points!!!!!!!!
Answer:
30
Step-by-step explanation:
There are 14 data points on the plot
The median is the middle value, which is between the 7th and 8th data points
Since it is even, we find the average of the 7th and 8th data points
Add the 7th and 8Th data points values and divide by 2
( 30+30)/2 = 60/2 = 30
The median is 30
Answer:
30
Step-by-step explanation:
Middle numbers are 30 and 30 so you add them and then divide by two:
[tex]\frac{30 + 30}{2}[/tex] = [tex]\frac{60}{2}[/tex]= 30
Which of the following illustrates the truth value of the given conditional statement?
p. 10 > 7
q. 10 > 5
p-~q
Answer:
T T → T
Step-by-step explanation:
Given :
p = 10 > 7
q = 10 > 5
Evaluating if the statements are true :
p = 10 > 7, This is TRUE, Because 10 is truly greater Than 7
q = 10 > 5, This is TRUE, Because 10 is truly greater Than 5
The statements are both True statements :
p = True ; q = True
True and True = True
T & T = T
T T → T
Jeff can build 7 birdhouses in 5 hours. Use a
proportion to find out how long it would take
him to build 30 birdhouses. (Round answer to
nearest whole number)
Answer:
21 hours
Step-by-step explanation:
We can use a ratio to solve
7 houses 30 houses
------------- = --------------
5 hours x hours
Using cross products
7x = 5*30
7x = 150
Divide by 7
7x/7 =150/7
x =21.42857143
Rounding to the nearest whole number
x = 21 hours
What is the solution of the equation, 8y = 4?
A. y = 1/2
B. y = 2
c. y = 12
D. y = 32
Answer: A, which is y = 1/2
Step-by-step explanation: To find the value of y, you would need to divide both of the sides by 8. This makes it so that 8y turns into just y. After you do this, you would find an answer of y = 1/2. Hope this was helpful! :)
Answer:
y = 1/2
Step-by-step explanation:
8y = 4
Divide each side by 8
8y/8 = 4/8
y = 1/2
A box in the shape of a rectangular prism has the length of 3 5/8 inches, a width of 2 1/2 inches and a height of 4 inches. What is the volume of the box?
Answer:
36 1/4 in^3 : 36.25 in ^3
Step-by-step explanation:
Turn all fractions into decimal form:
3 5/8 in = 3.625
2 1/2 = 2.5
4 = 4
Volume formula = lwh
l = 3.625 in
w = 2.5 in
h = 4 in
V = 3.625 * 2.5 * 4
V = 9.0625 * 4
V = 36.25

A special effects engineer is designing a model of an airplane for some shots in a movie.The wingspan of the model is 8.4 meters wide as shown below. If the scale used to create the model was 1/4 the actual wingspan; what was the true wingspan of the oringal plane?
Answer:
33.6 meters
Step-by-step explanation:
the wingspan is 1/4 of the original size so all you need to do is multiply the scaled down wingspan by 4

Answer:
a = 153.5 yd²
Step-by-step explanation:
horizontally divide the figure into a tringle and a trapezoid
triangle
a = (1/2)bh
a = (1/2)(19)(7)
a = 66.5
trapezoid
a = (b₁ + b₂)/2 * h
a = (19 + 10)/2 * (13 - 7)
a = 87
Combined
a = 66.5 + 87
a = 153.5
What is distributive property in math?
Answer:
The distributive property is one of the most frequently used properties in math. The distributive property lets you multiply a sum by multiplying each addend separately and then add the products.
distributive property is multiplying a number by a sum is the same as doing each multiplication separately.
for example: 2 (4 + 3 )
2 x 4 = 8
2 x 3=6
8+6=14

find the coordinate for the mid point of the segment with the points given (-16,0)(0,-16)
(-8,-8)
(8,0)
(8,8)
Answer:
(-8,-8)
Step-by-step explanation:
Coordinates of a midpoint:
The coordinates of the midpoint of a segment is given by the mean of the coordinates of the endpoints.
In this question:
Endpoints (-16,0) and (0,-16).
x-coordinate:
[tex]\frac{-16+0}{2} = -8[/tex]
y-coordinate:
[tex]\frac{0-16}{2} = -8[/tex]
Then:
(-8,-8)
A car rental costs $32 as a base fee, plus $28 per day. Use the explicit rule f (n )= 28n + 32
Find the charges paid for the first 4 days
Answer:
The charges paid for the first four days are:
$144.Step-by-step explanation:
To obtain the charges paid for the first 4 days, you must use the given explicit rule given:
f (n) = 28n + 32Where:
n = Number of days the person rents the car.As we need to obtain the charges to 4 days, we replace this value in the explicit rule:
f (n) = 28n + 32f (4) = 28(4) + 32f (4) = 112 + 32f (4) = 144With these calculations, you can identify the charges paid for the first 4 days are $144, where $112 is the money by each day of the four days and $32 is the base fee.
