Answer:
Kadie is correct
Step-by-step explanation:
There are 3 people (including Kadie). Kadie said that you can write the expression by multiplying 3 by all of the admissions and fees for the three things they did at the dance. By doing this and adding up the result, you get the money that needs to be paid at the dance for all three of them.
Hope this helps!
Aiden invested $98,000 in an account paying an interest rate of 2 3/8% compounded
continuously. Autumn invested $98,000 in an account paying an interest rate of 2 3/4%
compounded quarterly. After 11 years, how much more money would Autumn have in
her account than Aiden, to the nearest dollar?
Answer:
Aiden will have $17878 more than autumn
Step-by-step explanation:
For Aiden;
Formula for continuous compounding is;
FV = Pe^(rt)
P = 98000
r = 2⅜% = 0.02375
t = 11
Thus;
FV = 98000 × e^(0.02375 × 11)
FV = 127258.1218
For Autumn;
Formula for regular compounding;
FV = PV(1 + (r/n))^(nt)
Where;
PV is present value = 98000
r is rate = 2¾% = 0.0275
n is number of times amount is compounding = quarterly = 4
t is time in years = 11
Thus;
FV = 98000 + (1 + (0.0275/4))^(4 × 11)
FV = 98001.3518
Difference in their compounded amounts after 11 years is;
127258.1218 - 98001.3518 = 29256.77 ≈ $17878

Which graph represents a function with direct variation?
Find the angle (if it exists) in the interval [0, 2 ) for which sin = cos
Answer:
θ = π/4 over the interval [0,2)
Step-by-step explanation:
sinθ=cosθ
sinθ/cosθ=1
tanθ=1
θ = π/4 + πn
Because the domain is restricted to the interval [0,2) the only angle that exists which satisfies the interval is π/4. See the graph for a visual.

Answer:
D. The trench has become shallower because -32 is farther from 0 on a number line than -27
Answer: D
Step-by-step explanation: -27 is closer to zero than -32. Since these numbers were negative and the depth of the trench went from -32 to -27, we can assume that the trench had gotten more shallow.

Step-by-step explanation:
Suppose a male and a female of a certain species of animal were taken to a deserted island. The population of this species quadruples (multiplies by 4) every year. Assume that the animals have an abundant food supply and that there are no predators on the island.
What is an equation that can be used to model the population of the species?
Complete the equation below
f(n) = _______________
Use n as your variable.
Use the ^ symbol to represent an exponent.
For example: 52 should be typed as 5^2
Answer:
f(n) = 2 * 4^n
Step-by-step explanation:
The initial population = a male and a female = 2
The population quadruple every year, this means, a multiplication by 4 every year.
Hence, we have :
f(n) = (Initial population * multiple^years)
f(n) = 2 * 4^n

. Determine f(4.5) for the function f(x) = 3x - 5 *
Algebra
f(4.5)=8.5
Plug in x as 4.5 and multiply it with 3. Then subtract 5 from the remaining result.
Answer:
f(4.5) = 8.5
Step-by-step explanation:
f(4.5) = 3x - 5
f(4.5) = 3(4.5) - 5
f(4.5) = 13.5 - 5
f(4.5) = 8.5
Hope that helped! You have to substitute x with 4.5 and then solve.

Find the diameter of the circle. Assume the leg of the triangle is tangent to the circle. Round any decimals to the nearest tenth.
Answer:
8.7 units
Step-by-step explanation:
Given is a right angled triangle (because the segment with 5 units length is tangent to circle. Tangent is perpendicular to RADIUS or diameter)
Let the length of the diameter be d units
By Pythagoras Theorem:
[tex]d = \sqrt{ {10}^{2} - {5}^{2} } \\ = \sqrt{100 - 25} \\ = \sqrt{75} \\ = 8.66025404 \\ = 8.7 \: units[/tex]

Answer:
[tex]9600 \: {ft}^{2} \\ [/tex]
Step-by-step explanation:
Area of front rectangle -
= 2 ( length × breadth )
= 2 ( 40 × 30 )
= 2 ( 1200)
[tex] = {2400 \: ft}^{2} \\ [/tex]
Area of other rectangles -

12. Given triangle ABC with sides a, b, and c
opposite angles A, B, and C, respectively,
determine which side is the longest if
MZA = 49°, mZB = 24°, and mZC = 107°.
If you need, construct this triangle on a sheet of paper.
side c
side a
side b
Impossible to determine
Answer:
Side c
Step-by-step explanation:
Generally triangles can be classified with respect to their sides, or their angles. And there is a relationship between the length of the sides and the measure of the opposite angles of a given triangle. The relationship is that; the longest length of side is the one that is always opposite to the greatest angle.
In the given question, the longest side given that m<A = 49°, m<B = 24°, and m<C = 107° of the internal angles of the triangle is side c. Since side c is opposite the greatest angle, <C.

A hiker in Africa discovers a skull that contains 63% of its original amount of C-14. Find the age of the skull to the nearest year.
What is the surface area of this right cone?
Answer:
Step-by-step explanation:
Slant height s = 12
Radius r = 8
Lateral area of cone = πrs = 96π units²
Base area of cone = πr² 64π units²
Surface area = 96π + 64π = 160π units²
