write the log equation as an exponential equation
Answer:
[tex] \displaystyle {9}^{2x - 1} = 2[/tex]
Step-by-step explanation:
we are given a logarithmic equation
[tex] \displaystyle \log_{9}(2) = 2x - 1[/tex]
we want to rewrite it as exponential equation
remember that,
[tex] \displaystyle\log_{a}(b) = c \iff {a}^{c} = b[/tex]
here our a is 9,b is 2 and c is 2x-1
altogether
our exponential equation is
[tex] \displaystyle {9}^{2x - 1} = 2[/tex]
and we're done!

find the area of the shaded region to the nearest tenth
Answer:
Area of shaded region = 13.07 unit² (Approx.)
Step-by-step explanation:
Given:
Given shaded region is a segment
Radius of circle = 12
Given angle = 60°
Find:
Area of shaded region
Computation:
Area of shaded region = Area of segment
Area of segment = (θ/360)(π)(r²) - (1/2)(sinθ)(r²)
Area of segment = (60/360)(22/7)(12²) - (1/2)(sin60)(12²)
Area of segment = (0.1667)(3.14)(144) - (0.5)(0.866)(144)
Area of segment = (75.42) - (62.35)
Area of segment = 13.07 unit²
Area of shaded region = 13.07 unit² (Approx.)

Answer:
9) 379.94 mm2
10)19.625 ft2
Step-by-step explanation:
a=(pi)r2
a=3.14(11 mm2)
a=3.14(121 mm2)
a=3.14*121 mm2
a=379.94 mm2
a=(pi)r2
a=3.14(2.5 ft2)
a=3.14(6.25 ft2)
a=3.14*6.25ft2
a=19.625 ft2
Answer:
(I don't know where to round the numbers to, so I'll just put the full areas)
The answer to 9. is: 380.132711 mm², and the answer to 10. is: 19.6349541 ft².
Step-by-step explanation:
The formula for the area of a circle is A = πr². (A = area, π = pi, r = radius.) When you substitute the variables in the formula for the values of question #9, you get A = π(11)². (It's 11 because the radius is half of the diameter, which in this case is 22 mm.) And when you substitute the variables for the values of question #10, you get A = π(2.5)². And from there, you just finish the equations. Hope this helps :)
Determite weather the ordered pair is a solution of the linear equation x=y+1/2;(-5,-2)
Answer:
(y+1/2 ; y)
Step-by-step explanation:
hello : all ordered pair is a solution of the linear equation x=y+1/2;(-5,-2) is :
(y+1/2 ; y)
(-5 ; -2) is not solution because y = -2 but -2+1/2 = -3/2 no -5
An account earns simple interest.
$1675 at 4.6% for 4 years
a. Find the interest earned.
$
b. Find the balance of the account.
$
a. The interest earned is $307.40.
b. The balance of the account after 4 years is $1982.40.
What is simple interest?Simple interest is a type of interest that is calculated only on the principal amount of a loan or investment. It is a fixed percentage of the principal amount that is added to the loan or investment balance over a specified period of time.The formula for simple interest is:
I = P * r * t
What is principal?In finance, the term "principal" usually refers to the initial amount of money that is borrowed or invested, excluding any interest or other fees that may be added on later.
In the given question,
a. To find the interest earned, we can use the formula:
Interest = Principal x Rate x Time
where Principal is the initial amount of money, Rate is the interest rate, and Time is the duration of the investment. Plugging in the given values, we get:
Interest = $1675 x 0.046 x 4
Interest = $307.40
Therefore, the interest earned is $307.40.
b. To find the balance of the account, we simply add the interest earned to the initial amount:
Balance = Principal + Interest
Balance = $1675 + $307.40
Balance = $1982.40
Therefore, the balance of the account after 4 years is $1982.40.

Answer: 75%
Step-by-step explanation:
We convert 2 litres into 1000ml which leaves us with:
750/1000 x 100 = 75%
Answer:
37.5%

The probability at being stopped at the first light and second light is 0.3. What is your probability of being stopped at the first light or second light?Make sure to show your work. NEED HELP ASAP. The correct answer was .8 I just don't know how. Thank you.
Answer:
0.54 or 54%
Step-by-step explanation:
P( 1st but not second) = P(1st) - P(1st and Second) = 0.4 - 0.28 = 0.12 = 12%
P( 2nd but not first) = P(2nd) - P(1st and Second) = 0.7 - 0.28 = 0.42 = 42%
Probability of 1 of them (exactly one) = P( 1st but not second) + P( 2nd but not first) = 0.12 (12%) + 0.42 (42%) = 0.54 or also 54%.

Which of the following is an equation of the line that has a slope of - 3 and passes through the point (-6, 2)?
Answer:
y = -3x - 16
Step-by-step explanation:
m = -3 ; (-6 , 2)
Slope point form : y - y1 = m(x -x1)
y - 2 = -3(x - [-6])
y - 2 = -3(x + 6)
y -2 = -3x + 6*(-3)
y - 2 = -3x - 18
y = -3x - 18 + 2
y = -3x - 16

Can the theoretical probability of the cup landing on its side be calculated based on the information given?
Answer:
If given enough information yes
Step-by-step explanation:
If you were given the weight and the distibution of the weight and the elasticity of the cup, as well as the trajectory of the cup and the force it was thrown at, and the proportions of the cup, its shape, where it's landing, etc. You could give a definitive probability. For example, If there is more weight at the bottom of the cup it might be less probable to land on it's side
a. These triangles are proportional. Identify which sides match up between the two triangles. Please note sides are named from point to point so for instance the length 40 on triangle ABC is referred to as side AB. Make sure to identify all three pairs. b. Set up fractions with your side pairs to show proportionality. Do they all simplify down to the same fraction? If not please go back to Part A and remember that shapes can be rotated or reflected. Make sure to show your work demonstrating that the fractions are proportional. c. Are the triangles similar? If so explain why. If not, explain why not. Your work from Part A & B may help with this.
