$870 is invested in an account earning 2.9% interest (APR),
compounded continuously. Write a function showing the
value of the account after t years, where the annual growth
rate can be found from a constant in the function. Round all
coefficients in the function to four decimal places. Also,
determine the percentage of growth per year (APY), to the
nearest hundredth of a percent.
Answer:
Step-by-step explanation:
[tex]\text{Continuous compounding is}\\ \\ A=Pe^{rt}\\ \\ V=870e^{0.029t}\\ \\ \text{The yearly growth rate is}\\ \\ e^0.029\approx 1.0294\\ \\ \text{Which is a growth of }2.94\% [/tex]

What is the area of a circle that has a radius of 5 meters
Answer:
Step-by-step explanation:
area of circle = pi* r^2
Area = (3.14)*(5)^2
area= 78.5 m^2
Step-by-step answer:
The formula for the area of a circle is pi•r², so substitute 5 in for r.
pi•5²
Now, simplify the equation. Use PEMDAS.
There are no Parentheses, so we move on to Exponents.
pi•25
Now, we move to Multiplication.
P.S. If you are using 3.14 for pi, your answer is 78.5; otherwise, your answer is below.

Answer:
24
Step-by-step explanation:
There are 36 possible outcomes when rolling 2 dice. The sums range from 2 to 12. There are 4 ways of rolling a 9: 3, 6; 4, 5; 5, 4; 6, 3.
p(sum of 9) = 4/36 = 1/9
1/9 of the rolls are expected to have a sum of 9.
1/9 * 216 = 24

So i think it would be 1/2 (OR .5), or possibly 2 depending on what its asking.
Every number in X can be multiplied by 2 to receive y, or the numbers in y.
The linear equation would be x*2=y, making the linear function 2, UNLESS you want to take Y and DIVIDE it by 2, making it 1/2, linear equasion would be y*.5=x, or y/.5=2 OR y*1/2=x.
Hope this helps, I'm so sorry if its wrong, I'm not too good at linear functions, I'm pretty sure its 1/2.

A plant grows the same amount every week. Which graph matches the situation described? b e .
Answer:
Option A
Step-by-step explanation:
Let the height of plant is 'b' units.
Graph representing the height of the plant will have y-intercept = b units
Since, the plant is growing at the same rate every week,
And growth of the plant is continuous.
Therefore, graph will be a straight line and continuous.
Since, the height of the plant is always increasing,
Slope of the line will be positive.
Option A will be the answer.

In ΔABC , angle C is a right angle.
Which statement must be true?
A.sin A = cos B
B.sin A = tan B
C.sin B = tan A
D.sin B = cos B
Answer: Choice A. sin(A) = cos(B)
============================================================
Explanation:
The rule is that sin(A) = cos(B) if and only if A+B = 90.
Note how
sin(A) = opposite/hypotenuse = BC/ABcos(B) = adjacent/hypotenuse = BC/ABSince both result in the same fraction BC/AB, this helps us see why sin(A) = cos(B). Similarly, we can find that cos(A) = sin(B).
In the diagram below, the angles A and B are complementary, meaning they add to 90 degrees. So this trick only applies to right triangles.
The side lengths can be anything you want, as long as you're dealing with a right triangle.

One year later, the height of the tree is 2.4 m.
Calculate the percentage
increase in the height of the tree
over the year, correct to 1 d.p.

Raymond’s Bake Shop sold 26/1/2 dozen cupcakes on Saturday. On Friday,
the bake shop sold 19/3/4 dozen cupcakes. What is the approximate
percent increase in cupcake sales from Friday to Saturday?
Answer:percent increase in cupcake sales from Friday to Saturday= 34%
Step-by-step explanation:
Step 1
Percent increase = Increase in cup cakes/ Old amount of cupcakes x100
Cupcakes sold on Friday = 19 3/4
Cupcakes sold on Saturday = 261/2
Increase in sales =26 1/2 -- 19 3/4 ( we will change to decmal for easy solving)
=26.5 - 19.75= 6.75 or 6 3/4
Step 2
Percentage increase = (6 3/4)/ (19 3/4) x100
Percentage increase = 6.75/19.75 x 100
Percentage increase =0.341 x100 = 34%

On Aaron’s farm, 1/10 of the animals are cows, ⅖ of the animals are chickens,
and ¼ of the remaining animals are pigs. If there are 40 animals on Aaron’s farm,
how many pigs are on Aaron’s farm?
Answer:
There are 5 pigs on Aaron's farm
Step-by-step explanation:
1. Start with 40 animals
2. 1/10 of the animals are cows, so divide 40 by 10 and you will find that 4 of the animals are cows
3. 2/5 of the animals are chickens, so multiple 40 by 2 to get 80 and then divide 80 by 5 and you will find that 16 of the animals are chickens
4. Subtract the 4 cows and 16 chickens from the 40 total animals and you find there are 20 more animals that are neither cows nor chickens
5. Of the 20 remaining animals, 1/4 are pigs, so divide 20 by 4 and you will find that there are 5 pigs
Answer:
There are 5 pigs on Aaron's farm

A plane is going to fly 300 miles at a planned speed of 530 mph. The flight will have an average headwind of w miles per hour the entire time, meaning the plane is flying directly against the wind. The time
Tin hours of the flight is a function of the speed of the headwind w, in mph, and can be modeled by
300
T(W) =
530-W
At what value of w does the graph have a vertical asymptote ? Explain what this asymptote means in this situation.
Answer:
Step-by-step explanation:
T(100) represents that the plane flies against the wind at 110mph for 0.714 hours
What is an approximation?An approximation is anything that is similar to but not identical to something else. Rounding can be used to approximate a number.
Given that a plane is going to fly 300 miles at a planned speed of 530 mph. The equation is T(W) = ( 300 ) / ( 530 -W).
The value of approximation will be calculated as
T(W) = ( 300 ) / ( 530 -W).
T(110) = ( 300 ) / ( 530 - 110)
T(110) = (300 ) / ( 420)
T(110) = 0.714
T(100) represents that the plane flies against the wind at 110mph for 0.714 hours.

make two equations for each:
exactly one solution
no solutions
infinitely many solutions
Answer:
Two equations with exactly one solution
y=x
y=-x
Two equations with no solutions
y=x
y=x+1
Two equations with infinitely many solutions
x+y+1
2x+2y=2
Step-by-step explanation:
Let's use linear equations. The slope intercept form is
y=mx+b
m is the slope and b is the y intercept.
To make the equations have one solution, the two equations must represent lines that do not have the same slope, so that they intersect. We must choose different slopes, but any y intercepts will do. Example: Choose the slopes to be 1 and -1 and choose both y intercepts to be 0
y=x
y=-x
For there to be no solutions, all we need are the same slopes and different y intercepts, so that the lines are parallel and at different heights. Let's choose the slopes to be 1 and the y intercepts to be 0 and 1.
y=x
y=x+1
To get infinitely many solutions all we need is for the lines to be parallel with the same y intercept, so that they lie on top of each other. We could use
y=x
y=x
but your teacher probably wants something different. So, lets use another form of a linear equation, the so-called standard form.
ax+by=c
if you solve this for y, you get
y=-(a/b)x+(c/b)
This is in the y=mx+b form we used before, except that now the slope is -(a/b) and the y intercept is (c/b). So, we will get the same slope if the ratio of a to b is the same for both equations and the ratio of c to b is the same for both equations. In other words, simply choose a standard form equation and then get another by multiplying through by any number. In general
ax+by=c
and
kax+kby=kc
will do the trick. Here is an example.
x+y+1
2x+2y=2
