Answer:
(5x+4)(5x-6)
Step-by-step explanation:
[tex]25x^{2} -10x-24[/tex]
Separate into two parts, first realizing that the only two factor pairs for 25 are 5 and 5 or 1 and 25. Using 5 and 5 makes the most sense, so
(5x )(5x )
The other two numbers need to multiply to -24 and add up to -10.
Pairs that muliply to 24 could be 1 and 24, 2 and 12, 3 and 8, and 4 and 6. The more you factor the easier it will be to quickly discern which numbers to use. In this case, the right pair is 4 and 6. Because it needs to add up to -10, it should be 4 and -6 (because multiplying out, -30 + 20 = -10).
Thus, the final factored equation is (5x+4)(5x-6). You can check this by FOILing and making sure you get the original equation.
What is the solution to this equation?
2 x + 10 = 28
Record your answer in the space provided. Be sure to use the correct place value.
Answer:
[tex]2x + 10 = 28 \\ 2x = 28 - 10 \\ 2x = 18 \\ 2x \div 2 = 18 \div 2 \\ x = 14[/tex]

Find the value of x. Round the length to the nearest tenth. The diagram is not drawn to scale.
Answer:
x ≈ 2879.4 m
Step-by-step explanation:
Measure of ∠DAC = 10°
Measure of ∠DAB = 90°
Measure of ∠BAC = 90° - 10° = 80°
By applying cosine rule in ΔABC,
cos(80°) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{AB}{AC}[/tex]
0.17365 = [tex]\frac{500}{x}[/tex]
x = [tex]\frac{500}{0.17365}[/tex]
x = 2879.36
x ≈ 2879.4 m

Two angles are complementary. One angle is 18 degrees more than the other. What are the measures of the two angles?
Answer:
Step-by-step explanation:
x+y = 90°
x = y+18°
(y+18°) + y = 90°
2y = 72°
y = 36°
x = y+18° = 54°
Solve for x and y simultaneously

The area of the quadrilateral is (x² + 9x + 14).
Given is a quadrilateral with height equal to (x+7) and the base is (x+2), we need to find the area of the quadrilateral,
So, to find the area of a quadrilateral, we need to know the lengths of both the height and the base.
In this case, the height is given as (x+7) and the base is given as (x+2).
The formula to find the area of a quadrilateral is:
Area = (base × height)
Let's substitute the given values into the formula and solve for the area:
Area = [(x+2) × (x+7)]
To simplify the expression, let's expand the brackets:
Area = (x² + 7x + 2x + 14)
= (x² + 9x + 14)
So, the area of the quadrilateral is (x² + 9x + 14).

What will be the first negative term in the sequence 87,84,81
Answer:
a₃₁
Step-by-step explanation:
The terms have a common difference between consecutive terms, that is
d = 84 - 87 = 81 - 84 = - 3
This indicates the sequence is arithmetic with nth term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 87 and d = - 3 , then
[tex]a_{n}[/tex] = 87 - 3(n - 1) = 87 - 3n + 3 = 90 - 3n
To find when [tex]a_{n}[/tex] < 0 , solve
90 - 3n < 0 ( subtract 90 from both sides )
- 3n < - 90
Divide both sides by - 3, reversing the symbol as a result of dividing by a negative quantity, then
n > 30
Thus the 31st term will be the first negative term

In 2005 the U.S. Census Bureau reported that 68.9% of American families owned their homes. Census data reveal that the ownership rate in one small city is much lower. The city council is debating a plan to offer tax breaks to first-time home buyers in order to encourage people to become homeowners. They decide to adopt the plan on a 2-year trial basis and use the data they collect to make a decision about continuing the tax breaks. Since this plan costs the city tax revenues, they will continue to use it only if there is strong evidence that the rate of home ownership is increasing. a) In words, what will their hypotheses be
Answer:
H0 : Number of homeowners stays the same
H1: Number of homeowners increases.
Step-by-step explanation:
The hypothesis is to test if the level of home ownership rises or doesn't.
For this type of experiment,
The null hypothesis is the current level of home ownership.
The alternative hypothesis which is usually the opposite of the null is meant to challenge the claim of the Null. Hence, the null hypothesis will support the claim or hypothesis of the study, which is that the number of homeowners increases, hence, does not remain the same.
Therefore,
H0 : Number of homeowners stays the same
H1: Number of homeowners increases.

A bullet fired from a gun has a muzzle velocity of 3510 km per hour how long dies it take to travel 100m
Answer:
A bullet fired from a gun has a muzzle velocity of 3510 km per hour how long dies it take to travel 100m
Step-by-step explanation:
Given :
Velocity of bullet = 3510 km/hr
Distance traveled = 100m
Converting distance in meter to kilometer :
(100 / 1000) km = 0.1 km
Recall :
Speed = Distance /time
Time taken = Distance / speed
Therefore,
Time taken = Distance / speed
Time taken = 0.1 km / 3510 km/hr
Time = 2.849 * 10^-5 hour

A person invests 3500 dollars in a bank. The bank pays 6.25% interest compounded annually. To the nearest tenth of a year, how long must the person leave the money in the bank until it reaches 11100 dollars?
The duration of time period required is 2.4 years.
What is a compound interest?Compound interest simply means that the interest associated with a bank account, loan, or investment increases exponentially over time.
Given that, A person invests 3500 dollars in a bank. The bank pays 6.25% interest compounded annually.
A = P(1+r/100)ⁿ
n = time
A = amount
P = principal
11100 = 3500(1+0.0625)ⁿ
3.171 = (1.0625)ⁿ
Taking log to both sides,
log(3.171) = nlog(1.0625)
n = 2.40
Hence, the required time is 2.4 years.
