Answer:
5(x +1.5)^210(x +1)^21/4(x +2)^23(x +5/6)^2Step-by-step explanation:
When your desired form is expanded, it becomes ...
a(x +b)^2 = a(x^2 +2bx +b^2) = ax^2 +2abx +ab^2
This tells you the overall factor (a) is the leading coefficient of the given trinomial. Factoring that out, you can find b as the root of the remaining constant.
a) 5x^2 +15x +11.25 = 5(x^2 +3x +2.25) = 5(x +1.5)^2
b) 10x^2 +20x +10 = 10(x^2 +2x +1) = 10(x +1)^2
c) 1/4x^2 +x +1 = 1/4(x^2 +4x +4) = 1/4(x +2)^2
d) 3x^2 +5x +25/12 = 3(x^2 +5/3x +25/36) = 3(x +5/6)^2
_____
Additional comment
If you know beforehand that the expressions can be factored this way, finding the two constants (a, b) is an almost trivial exercise. It gets trickier when you're trying to write a general expression in vertex form (this form with an added constant). For that, you must develop the value of b from the coefficient of the linear term inside parentheses.

What is the probability of rolling a 6 or landing on tails?
Enter your answer as a reduced fraction, like this: 3/14
Answer:
1/3
Step-by-step explanation:
If you are trying to figure out the more likeliness of getting tails than a 6, then you have to get a common denominator and then subtract numerators.
[tex]\frac{1}{2} =\frac{6}{12} \\\\\frac{1}{6} =\frac{2}{12} \\\\\frac{6}{12} -\frac{2}{12} =\frac{4}{12} \\\\\frac{4}{12} =\frac{2}{6} =\frac{1}{3}[/tex]
Theres a 1/3 more chance of tails than rolling 6
The probability of rolling a 6 or rolling a die is 2/3.
What is Probability?Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.
The value of probability will be always in the range from 0 to 1.
Given that,
An experiment consists of rolling a die and then flipping a coin.
Probability = Number of desired outcomes / Total outcomes
Probability of rolling a 6 = 1/6
Probability of landing on tails = 1/2
P(A or B) = P(A) + P(B)
Here, let A represents the event of rolling 1 6 and B represents the event of landing on tails.
P(A or B) = 1/6 + 1/2 = 4/6 = 2/3
Hence the required probability is 2/3.

The function f(x) = 5x² + 40x is a parabola. Then the vertex of the parabola will be at (–4, –80).
What is the parabola?It is the locus of a point that moves so that it is always the same distance from a non-movable point and a given line. The non-movable point is called focus and the non-movable line is called the directrix.
The function f(x) = 5x² + 40x
Then add and subtract 80, then we have
f(x) = 5x² + 40x + 80 – 80
f(x) = 5(x² + 8x + 16) – 80
f(x) = 5(x + 4)² – 80

Answer:
3p + 2s = 27.5
3p + 2s = 27.54p + 3s = 37.5
Multiplies first equation by 4 and second equation by -3
12p + 8s = 110
12p + 8s = 110-12p + -9s = -112.5
12p + 8s = 110-12p + -9s = -112.5Adding them together-s = -2.5s = 2.5
12p + 8s = 110-12p + -9s = -112.5Adding them together-s = -2.5s = 2.53p + 2(2.5) = 27.5
12p + 8s = 110-12p + -9s = -112.5Adding them together-s = -2.5s = 2.53p + 2(2.5) = 27.53p +5 = 27.53p = 22.5p = 7.5

A paper cup in the shape of a cone is used to get water from a water cooler. It has a height of 3 inches and a diameter of 22 inches
What is the lateral surface area of the paper cup to the nearest square Inch?
OA 15 square Inches
OB.
19 square Inches
ОС.
14 square Inches
OD. 18 square Inches
We will see that the lateral surface area of the cone is 14 square inches.
How to find the lateral surface area?
We know that for a cone of height H and radius R, the lateral surface of the cone is:
S = 3.14*R*H
In this case, we know that eh height is 3 + 5/8 inches, and the diameter is 2 + 1/2 inches. Remember that the diameter is twice the radius, then:
R = (2 + 1/2) in = (1 + 1/4) in
Replacing that on the surface equation, we will get:
S = 3.14*( (1 + 1/4) in)*(3 + 5/8)in = 14 in^2

Write a congruence statement for the pair of triangles shown.
Answer:
Triangle UTS is congruent to Triangle RST.
Step-by-step explanation:
When stating congruence, the corresponding angles and sides must be listed in order. In triangle uts, based on the points, the angle is U, and the side is US. This means that for the other triangle, the first point needs to be the angle, and the last one needs to be the other point for the side. This gives us Triangle UTS is congruent to triangle RST.

Find the volume of a right circular cone that has a height of 3.5 ft and a base
with a diameter of 11.9 ft.
Step-by-step explanation:
the volume of a cone is
base area × height / 3
and the case area is a circle, so we get
pi×r²×h/3
with e being the radius (half of the diameter), and h being the height.
therefore
pi×(11.9/2)²×3.5/3 = pi×(5.95)²×3.5/3 = 41.30291667... ft³

Answer:
9. a = -1
10. b = 20
Step-by-step explanation:
The term "cross multiplying" is used to describe the appearance of the result of multiplying both sides of the equation by the product of the denominators. The result is the left numerator is multiplied by the right denominator, and the right numerator is multiplied by the left denominator. The property of equality that supports this is the multiplication property of equality, which tells you the values of the variables are unchanged if you multiply both sides by the same thing. That multiplier is chosen so that it cancels the denominators.

a number is divisible by 11 if
Answer:
Solution : A number is divisible by 11, if the difference of sum of its digits in odd places from the right side and the sum of its digits in even places from the right side is divisible by 11. Since difference is 11 which is divisible by 11, therefore 5918 is divisible by 11.

Employee identification codes at a company contain 2 letters followed by 4 digits. Assume that all codes are equally likely. Identify the probability that an ID code does not contain the letter I.
A. 0.9246
B. 0.6567
C. 0.7493
D. 0.8321
Using it's concept, it is found that the probability that an ID code does not contain the letter I is given by:
A. 0.9246
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
Considering that for each letter there are 26 possible outcomes and for each digit there are 10 possible outcomes, the total number of outcomes is given by:
T = 26 x 26 x 10 x 10 x 10 x 10 = 6,760,000.
Without the letter "l", the desired number is given by:
D = 25 x 25 x 10 x 10 x 10 x 10 = 6,250,000.
Hence, the probability is given by:
p = 6,250,000/6,760,000 = 0.9246.

You find an apartment which charges 925 a month rent. each year the rent increases by 6% a. write a sequence that represents the rent paid each year for the first 5 years.
Answer:
In the first 5 years, 138,750$ worth of rent will already have been paid.
Step-by-step explanation:
Since you have to pay 925$ a month worth of rent, in only 1 year, 5,550$ rent money will already have been payed. Now, multiply 925 x 5 x 30 = 138,750. Since the rent increases by 6% every year, in the first 5 years it would have already increased to 30%. So therefore, you would have to pay 138,750$ money worth of rent.
