Answer:
Step-by-step explanation:
Factorize the denominator
Sum = 4
Product = 3
Factors = 1 , 3 {1*3 = 3 and 1+3 = 4}
x² + 4x + 3 = x² + x + 3x + 1*3
= x(x + 1) + 3(x + 1)
= (x + 1)(x + 3)
GCF of the numerator and denominator = (x + 3)

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

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).

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°
Which of the following equations is equivalent to y-3 = -2(x-6)?
а. y=-5x-9
b. y = -2x 3
с. y= -5x - 15
d. y = -2x + 9
Answer:
Step-by-step explanation:
Which of the following equations is equivalent to y-3=-2(x-6): y+3x=6 ... Move the +3*x to the right side by subtracting 3*x from (or adding negative 3*x to) ... And in addition, we know that the line graph crosses the y-axis where y equals y=-2x3.
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.

What is 23x9+37-213+(5x12)
Answer: 91
is that a x or multiply?
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.

b. (2,6)
c. (-4,1)
d. (6,5)
e. (-5,0)
f. none of the above
Answer: C,E
Step-by-step explanation: This is because when we plug in 5 for x and for y in the first inequality we get.
-3(5)-5>-4
Which equals -20>-4 and thats false so thats not it.
Then we got to (2,6) and we plug 2 for x and 6 for y and get:
-3(2)-6>-4
Which is -12>-4 which is false so thats also not it.
Then we got to C and we plug in -4 for x and 1 for y and we get:
-3(-4)-1>-4 and we get 12-1>-4
This is correct so we plug it in to the next inequality and get:
2(-4)-1<-2 and we get -9<-2 which is true
So C is an answer and we go on to d and e
For d we plug in 6 for x and 5 for y and we get:
-3(6)-5>-4 which is -23>-4 which is false so its not d
And then we go to e which is -5 for x and 0 for y and we plug in and we get:
-3(-5)-0>-4 This is 15>-4 which is true so we go to the next inequality and we plug in -5 for x and 0 for y and we get:
2(-5)-5(0)<-2 This is -10<-2 which is true so e is the other answer so the answers are

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
