Step-by-step explanation:
| a b |
| c d |
det = ad - bc
| x 4 |
| 3 x |
det = x * x - 4 * 3 = x^2 - 12
x^2 - 12 = 13

Which equation has solution x = -3? *
2x - 7 = -1
3x + 8 = 1
1/2x + 8 = 10
1/2(2x - 6) = -6
Please help me
Answer:
1/2(2x-6)= -6
Step-by-step explanation:
Multiply the two sides by the equation 2
2x-6=12
move the constant to the right hand side change sign
2x = -12 + 6
calculate the sum
2x= -6
Divide the 2 sides by 2

omar tariq has a credit card that uses the unpaid balance method to compute the finance charge. His monthly periodic rate is 2.4% during his billing cycle he charged a total of of 256.28 and made payments totaling $350. If he has a finance charge of 18.28, find his (a) unpaid balance (b) previous balance and (c) his new balance
Answer:
(a) unpaid balance = $667.95
(b) Previous balance = $761.67
(c) his new balance = $683.98
Step-by-step explanation:
In the question, we are given the following:
Monthly periodic rate = 2.4%, or 0.024
Curren charges = $256.28
Total payment made = $350
Finance charge = $18.28
Therefore, we now proceed as follows:
(a) unpaid balance
This can be calculated as follows:
Unpaid balance = Previous balance + Current charges - Total payment made ................. (1)
Note that from part (b), Previous balance is equal to $761.67.
Substituting this and other values from the question into equation (1), we have:
Unpaid balance = $761.67 + $256.28 - $350 = $667.95
(b) Previous balance
This can be calculated as follows:
Previous balance = Finance charges / Monthly periodic rate = $18.28 / 2.4% = $18.28 / 0.024 = $761.67
(c) his new balance
This can be calculated as follows:
New balance = Unpaid balance * (1 + Monthly periodic rate) = $667.95 * (1 + 2.4%) = $667.95 * (1 + 0.024) = $667.95 * 1.024 = $683.98

A radio station tower was built in two sections. From a point that is 70 feet from the base of the tower, the angle of elevation to the top of the section is 28 degrees, and the angle of elevation to the top of the second section is 40 degrees. What is the height of the top section of the tower to the nearest tenth of a foot?
Answer:
21.5 feet
Step-by-step explanation:
d = Distance of the bottom of the tower to the point of observation
x = Height of the top section of the tower
a = Height of bottom section
b = Total height of tower
[tex]\tan28^{\circ}=\dfrac{a}{d}\\\Rightarrow a=d\tan28^{\circ}\\\Rightarrow a=70\tan28^{\circ}[/tex]
[tex]\tan40^{\circ}=\dfrac{b}{d}\\\Rightarrow b=d\tan40^{\circ}\\\Rightarrow b=70\tan40^{\circ}[/tex]
[tex]x=b-a\\\Rightarrow x=70\tan40^{\circ}-70\tan28^{\circ}\\\Rightarrow x=70(\tan40^{\circ}-\tan28^{\circ})\\\Rightarrow x=21.5\ \text{feet}[/tex]
The height of the top section of the tower is 21.5 feet.
Lillian is going to invest in an account paying an interest rate of 5.7% compounded continuously. How much would Lillian need to invest, to the nearest ten dollars, for the value of the account to reach $7,600 in 7 years?
Answer:
The amount Lilian needs to invest is $5,160
Step-by-step explanation:
The parameters of the amount Lilian is going to invest in an account are;
The interest rate the account pays = 5.7%
The final amount the investment is expected to reach after the given time period = $7,600
The number of years of the investment = 7 years
The formula for compound interest is presented as follows;
[tex]A = P \cdot \left(1 + \dfrac{r}{n} \right)^{n\cdot t}[/tex]
Where;
A = The final amount = $7,600
P = The amount Lilian is to invest
r = The interest rate = 5.7% = 0.057
n = The number of times the interest is applied per time period = 1
t = The number of period that passes = 7 (years)
Therefore, we get;
[tex]7,600 = P \cdot \left(1 + 0.057 \right)^{7}[/tex]
∴ P = 7,600/(1 + 0.057)⁷ = 5,155.7123754
The amount Lilian needs to invest (rounded to the nearest ten dollars) for the value of the account to reach $7,600 in 7 years, P = $5,160

After checking that conditions are met, you perform a significance test of 0:=1 versus :≠1 . You obtain a -value of 0.022.
Which of the following must be true?
A 95% confidence interval for will include the value 0.022.
A 99% confidence interval for will include the value 1.
None of these is necessarily true.
A 99% confidence interval for will include the value 0.022.
A 95% confidence interval for will include the value 1.
Answer:
A
Step-by-step explanation:
The true statement is
A 99% confidence interval for will include the value 1.
What is Confidence Interval?The range of values that we observe in our sample and for which we anticipate finding the value that accurately reflects the population is referred to as a confidence interval.
Given:
[tex]H_0: \mu = 1\\H_\alpha : \mu \neq 1[/tex]
P= 0.022
If the P- value is smaller than significance level, then the null hypothesis is rejected.
P< 0.05 - 5% Reject [tex]H_0[/tex]
P> 0.01 = 1% Fail to Reject [tex]H_0[/tex]
A 95% Confidence interval correspond with a significance test at the 5%
significance level.
A 99% Confidence interval correspond with a significance test at the 1%
significance level.
If the Significance test was Significant then the interval does not contain the value mentioned in the Hypothesis.
95% CI does not contains 1.
99% CI contains 1.

The perimeter of a square patio is (8x - 28). What is the length of one side?
Answer:
Length is 7, Permimeter is 28
Step-by-step explanation:
Perimeter=4×side

Find the dimensions or, the square or circle. Area = 64π in²
Answer:
r = 8 inches
Step-by-step explanation:
We know that formula for area of a circle is; A = πr²
Where r is radius.
We are given Area as 64π in²
Thus;
πr² = 64π
π will cancel out to give;
r² = 64
r = √64

Cindy throws one red and one blue regular (six-sided) fair dice. Find the probability that the sum of the two dice is greater than 2.
a 1/36
b 35/36
c 33/36
d 1
Answer:
5/36 is your answer.
Step-by-step explanation:
If the red die shows a "2", then the blue die must take on the values from the set {2,3, 4, 5, 6} in order for the sum of both dice to be larger than 4.
1+2=3
2+3 = 5
2+4 = 6
2+5 = 7
2+6 = 8
There are 6*6 = 36 total ways to roll two dice and exactly 5 ways to get the conditions stated above. The probability of getting a sum greater than 2 is 5/36
The probability that the sum of the two dice is greater than 2 will be 35/36. Then the correct option is B.
What is probability?Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences. Then the probability is given as,
P = (Favorable event) / (Total event)
Cindy throws one red and one blue regular (six-sided) fair dice. The total number of events will be
Total events = 6 x 6 = 36
The probability that the sum of the two dice is greater than 2 will be given as
P = 1 - 1 / 36
P = 35 / 36
The probability that the sum of the two dice is greater than 2 will be 35/36. Then the correct option is B.

Find the area of the figure.
Answer and Step-by-step explanation:
For this shape, we have to draw a line that goes through the point that is inside of the shape from top to bottom.
This creates a square and two triangles.
The area formula for a triangle is A = [tex]\frac{bh}{2}[/tex]
The area of a square is A = b*b
Half of 3 is 1.5.
Triangles (Area combined):
Since there are two triangles that are the same, we only need to find the area of of 1 triangle, and not divide by 2.
A = 3 × 1.5 = 4.5
Square:
A = 3 × 3 = 9
Now, we add them together to get the total area of the figure.
9 + 4.5 = 13.5

The Weston family spends a maximum of
$50.00 per month on entertainment. Write and
graph an inequality to represent this.
Answer:
y < 50x
Step-by-step explanation:
In order to graph this inequality, you first need to identify the important word(s) here to find the inequality sign; in this case, it would be "maximum of $50" a month. Since it's a maximum of $50 a month (or less than $50 a month), you can write it as:
Where m is months and c is total cost, c < 50m
If you need to graph this, you can write it as y < 50x. The cost is y since it's the output, and months is x since that's the input.
