Answer:
[tex]y=11*3^x[/tex]
Here is the graph showing this function.
Answer:
[tex]\sf y = 11(3)^x[/tex]
given points: ( 0, 11) , (2,99)
solve for 1st
[tex]\sf y = ab^x[/tex]
[tex]\sf 11 = ab^0[/tex]
since we know [tex]\sf b^0 = 1[/tex]
[tex]\sf 11 =a[/tex]
solve for 2nd
[tex]\sf y = ab^x[/tex]
[tex]\sf 99 = ab^2[/tex]
[tex]\sf \dfrac{99}{b^2} = a[/tex]
solve simultaneously:
[tex]\sf 11 = \sf \dfrac{99}{b^2}[/tex]
[tex]\sf 11 b^2= \sf 99}[/tex]
[tex]\sf b^2= 9[/tex]
[tex]\sf b = 3[/tex]
Therefore equation: [tex]\sf y = 11(3)^x[/tex]

10. Depression. A study published in the Archives of

General Psychiatry in March 2001 examined the
impact of depression on a patient's ability to survive
cardiac disease. Researchers identified 450 people
with cardiac disease, evaluated them for depression,
and followed the group for 4 years. Of the 361
patients with no depression, 67 died. Of the 89
patients with minor or major depression, 26 died.
Among people who suffer from cardiac disease, are
depressed patients more likely to die than
nondepressed ones?
a) What kind of design was used to collect these
data?
b) Write appropriate hypotheses.
c) Are the assumptions and conditions necessary for
inference satisfied?
d) Test the hypothesis and state your conclusion,
e) Explain in this context what your P-value means.
f) If your conclusion is actually incorrect, which type of
error did you commit?
Among people who suffer from cardiac disease, are depressed patients more likely to die than nondepressed ones?
Yes, they are.a) The kind of design which was used to collect these data is:
Quantitative Research Design:b) The appropriate hypotheses is:
People who are depressed are more likely to die from cardiac arrest than people who are not depressed.c) Are the assumptions and conditions necessary for inference satisfied?
No, it is not. More tests and samples need to be concluded to make sure that it is not a chance occurrence.d) Test the hypothesis and state your conclusion,
The hypothesis made is consistent with the statistical data but there needs to be more observation and independent variables used.e) The best explanation of this context based on what your P-value means is:
The measure of probability of the observed difference between the groups of people shows that there is a small chance for the results being as a result of a random chance.f) If your conclusion is actually incorrect, the type of error which was committed is:

In order to join a dancing club there is a $30 startup fee and a $4 monthly fee. Write an equation in slope intercept form that models this situation.
Answer:
y = 4x + 30
Step-by-step explanation:
The startup fee is $30 and must be paid before you begin. This means that 30 in the y-intercept. You pay $30 at 0 months. Then you have to pay $4 every month after that. This means that 4 is the slope. So, after x months, the total amount you have paid, y, is

The floor of a moving van is 3 feet off of the ground. The ramp into the van makes a 22. 3 angle with the ground. How long is the ramp?
12. 0 feet
7. 3 feet
3. 2 feet
7. 9 feet
Answer:
(d) 7.9 ft
Step-by-step explanation:
The geometry of the problem can be represented by a right triangle whose hypotenuse is the ramp, and the side opposite the given angle is 3 feet. Then the relevant trig relation is ...
Sin = Opposite/Hypotenuse
Solving for Hypotenuse, we find ...
Hypotenuse = Opposite/Sin
ramp length = (3 ft)/sin(22.3°) ≈ 7.9 ft
The ramp is about 7.9 feet long.

A dog is leashed to the corner of a house. How much running area does the dog have? Round your answer to the nearest square foot, if necessary.
Answer:
300pi square feet
Step-by-step explanation:
the dog can move inside of the 3/4 of a circle
the area of a circle is the radius squared times pi
20*20*pi=400pi
Since the house takes up 1/4 of the circle the dog is left with 3/4
400pi*3/4=300pi
PLEASE HELP Solve for x. Round to the nearest tenth, if necessary.
ANSWER:
2.1
EXPLANATION:
angle = 38
opposite side = 1.3
hypotenuse = X
Based on this we must use sine (opposite / hypotenuse)
sin (38⁰) = 1.3 / x
x = 1.3 / sin (38⁰) [use calculator]
x = 2.1

if 8^{y}=18^{y+2} what is the value of y?
Answer:
-8
Step-by-step explanation:
both 8^-8 and 16^-8+2 equal 5.9605
[tex][Hello,BrainlyUser][/tex]
Answer:
y = -8
Step-by-step explanation:
Create equivalent expressions in the equation that all have equal bases.
[tex]2^3^y=2^4^(^y^+^2^)[/tex]
Since the bases are the same, then two expressions are only equal if the exponents are also equal.
[tex]3y=4(y+2)[/tex]
Simplify
[tex]4(y+2).[/tex]
Apply the distributive property.
[tex]3y=4y+4*2[/tex]
Multiply 4 by 2
[tex]3y=4y+8[/tex]
Subtract 4y from both sides of the equation.
[tex]3y-4y=8[/tex]
Subtract 4y from 3y.
[tex]-y=8[/tex]
Multiply each term in −y=8 by −1
[tex]y=-8[/tex]
Hence, Answer is y = -8

Help solve this math problem thing pleasereeee
Step-by-step explanation:
We have the equation y = 2x - 5
To complete the table of values substitute each of the x values into the equation
When x = 0
y = 2(0) - 5 which means y =(2 × 0) - 5 = -5
The coordinates you plot are (0,-5)
When x = 1
y = 2(1) - 5 which means y = (2 × 1) - 5 = -3
The coordinates you plot are (1,-3)
When x = 2
y = 2(2) - 5 which means y = (2 × 2) - 5 = -1
The coordinates you plot are (2,-1)
When x = 3
y = 2(3) - 5 which means y = (2 × 3) - 5 = 1
The coordinates you plot are (3,1)
When x = 4
y = 2(4) - 5 which means y = (2 × 4) - 5 = 3
The coordinates you plot are (4,3)
When x = 5
y = 2(5) - 5 which means y = (2 × 5) - 5 = 5
The coordinates you plot are (5,5)
what is the area of this tile?
The area of the tile is 12 square inches.
How to get the area of a rectangle?
For a rectangle of length L and width W, the area is given by:
A = L*W
In this case, we can see that the width is 2 inches and the length is 6 inches, then the area of this rectangle will be:
A = 6in*2in = 12 in^2
So we can conclude that the area of the tile is 12 square inches.
