Find the value of x. show work
Step-by-step explanation:
it's a right triangle
Pythagorean theorem
the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse
x² = 9² - 2²
x² = 81 - 4
x² = 77
x = √77
or
x = 8.77

B.which integers are 10 units away from 5 on a number line?
C.Starting at -7 on a number line,Darcy moved 4 units to the right. What integer did Darcy land on?
Please answer thiss, thank you guys so much!!!!!!! :)
Answer:
a. -1
Subtracting 6-7 would give you -1. Negative 1 is 7 units from the number 6.
b. -5 and 15
Adding and subtracting 10 from 5 would give you -5 and 15.
c. -3
Starting at -7, and going to the right 4 means that Darcy moved +4. -7+4 would give you negative 3.

Marie has $60,000 in a savings account that earns 7% interest per year. How much will she have in 4 months?
Answer:
21,400
Solving steps:
Since, Marie has $60,000 in a savings account that earns 7% interest per year.
Find: How much will she have in 4 months.
[tex] \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: solution[/tex]
Step 1: Find the money for the 7% rate
=> [tex] 60000 \times \frac{7}{100} [/tex]
=> [tex] \frac{60000}{1} \times \frac{7}{100} [/tex]
cancel the two zeros of 60,000 and 100
=> 600 × 7
=> 4,200
Add 4,200 to 60,000
=> 64,200
per year = 64,200
Now, divide 64,200 by 12
since 12 months to make one year
=> 64,200 ÷ 12
=> 5,350
now multiply it by 4 months she gets 5350 per month
=> 21,400

Order the steps to factor the quadratic trinomial completely.
Answer:
1, 4, 3, 5, 6
Step-by-step explanation:
5(5x² - 9x) = 45x + 40 ← distribute parenthesis on left side
25x² - 45x = 45x + 40 ← subtract 45x + 40 from both sides
25x² - 90x - 40 = 0 ← factor out 5 from each term
5(5x² - 18x - 8) = 0
5(x(5x + 2) - 4(5x + 2))
5(x - 4)(5x + 2)
Answer:
The order is: 1, 4, 3, 5, 6
Step-by-step explanation:
5(5x² - 9x) = 45x + 40
25x² - 45x = 45x + 40
25x² - 90x - 40 = 0
5(5x² - 18x - 8) = 0
5(x(5x + 2) - 4(5x + 2)
5(x - 4)(5x + 2)
The order is: 1, 4, 3, 5, 6

Answer:
aₙ = a₁ * 2ⁿ⁺¹
Step-by-step explanation:
a₁ = 6
a₂ = 12
a₃ = 24
Note a₂/a₁ = 2 = a₃/a₂
So it is a geometric sequence with common ratio of 2
a₂ = a₁ * 2 = a₁ * 2¹ = a₁ * 2²⁺¹
a₃ = a₂ * 2 = a₁ * 2 * 2 = a₁ * 2² = a₁ * 2³⁺¹
Then
aₙ = a₁ * 2ⁿ⁺¹

Explanation:
The key thing to focus on is the phrasing "starting at the age of 8"
Specifically, your teacher wants the starting height when Mia was 8 years old. That height being 52 inches.
The 7 inches refers to how much she had grown over the 2 years, which is part of the rate of change (and will be part of the slope).
Side note: 52 inches = 4 ft, 4 inches
What is the solution to the equation below? In x= -4
A. X=0.31
B. X=0.02
C. X=-54.60
D. X=-1.39
Answer:
B. X=0.02
Step-by-step explanation:
The solution to the natural log equation is found by taking antilogs.
ln(x) = -4 . . . . . . . given equation
x = e^-4 . . . . . . . take antilogs
x ≈ 0.0183156
x ≈ 0.02 . . . . rounded to 2 decimal places
_____
Additional comment
Essentially, we use each side of the equation as a power of e.
e^ln(x) = e^(-4)
x = e^-4 . . . . . . . simplified
Choices C and D can be eliminated by the fact that ln(x) for x < 0 is undefined. x cannot be negative.

Please note that the units for each side MUST be the same (or if they're different, then the lengths have to be equivalent).
Looking at the answer choices, we can see that the last answer choice is a 1 yd by 1 yd by 1 yd cube, therefore it is a unit cube.

you record the number of sunny days out of a sample of 90 randomly selected days in city a and city b. in city a's sample there were 54 sunny days. in city b sample there were 63 sunny days.
Is City B significantly sunnier than City A? use a significance level of 0.05
The significance level shows that z approximately equals 1.41 for a p-value of 0.078642.
How to calculate the p-value?Based on the complete question, the sample proportion for city A will be:
= 54/90 = 0.60
The sample proportion for city B will be:
= 63/90 = 0.70
Using the table given, it can be deduced that the test statistic value will be 1.41. Therefore, the p-value will be 0.078652 in the Excel function.
Since the p-value is greater than 0.05, then we fail to reject the null hypothesis that there is no difference in the commute time.

Suppose that a household's monthly water bill (in dollars) is a linear function of the amount of water the household uses (in hundreds of cubic feet, HCF). When graphed, the function gives a line with a slope of 1.45. See the figure below.
If the monthly cost for 13 HCF is $46.33, what is the monthly cost for 17 HCF?
The monthly cost for 17 hundred of cubic feet is $52.13.
What is a linear equation?A linear equation is in the form:
y = mx + b
Where y,x are variables, m is the rate of change and b is the initial value of y.
Let y represent the bill paid for x HCF of water.
The slope is 1.45, hence m = 1.45.
The monthly cost for 13 HCF is $46.33, hence:
46.33 = 1.45(13) + b
b = 27.48
y = 1.45x + 27.48
For 17 HCF:
y = 1.45(17) + 27.48 = 52.13
The monthly cost for 17 hundred of cubic feet is $52.13.

6. Find the value of each missing variable.
Answer:
x = 110
y = 102
z = 82
Step-by-step explanation:
Angles that create a line are equal to 180
x + 70 = 180
x = 110
y + 78 = 180
y = 102
A quadrilateral's angles add up to 360
110 + 78 + 90 + z = 360
278 + z = 360
z = 82

Find the equation of the axis of symmetry of the parabola. Each box in the grid represents 1 unit.
Enter the answer as an equation.
Answer:
The axis of symmetry of this parabola will be the line x=−b2a .
Step-by-step explanation:
Graph the parabola y=x2−7x+2 .
Compare the equation with y=ax2+bx+c to find the values of a , b , and c .
Here, a=1,b=−7 and c=2 .
Use the values of the coefficients to write the equation of axis of symmetry .
The graph of a quadratic equation in the form y=ax2+bx+c has as its axis of symmetry the line x=−b2a . So, the equation of the axis of symmetry of the given parabola is x=−(−7)2(1) or x=72 .
Substitute x=72 in the equation to find the y -coordinate of the vertex.
y=(72)2−7(72)+2 =494−492+2 =49 − 98 + 84 =−414
Therefore, the coordinates of the vertex are (72,−414) .

Two types of tickets are available for a charity ball event: $18 for a reserved seat and $9 for general admission. The number of reserved seats available is 85 less than the number of tickets available for general admission. If the sale of tickets for the day was $3,600, how many seats were allotted for general admission?
Answer:
# of reserved seats = R; # of general admission seats = G
G - R = 85
$18R + $9G =$3600
Multiply 1st equation by 18: 18G - 18R = 1530
Rearrange 2nd equation: $9G + $18R =$3600
Combine the equations: 27 G = 5130
