Answer:
A=325(1.07)^t
Step-by-step explanation:
I got an 100 on the test
[tex]A=325(1.07)^t[/tex]shows the exponential growth rate of 7%
What is a function?A relation is a function if it has only One y-value for each x-value.
The formula for exponential growth is given by:
[tex]A = P(1 + r)^t[/tex]
where A is the amount after t periods, P is the initial amount, and r is the rate of growth.
To represent a growth rate of 7%, we can use:
[tex]A = 325(1 + 0.07)^t[/tex]
Hence, [tex]A=325(1.07)^t[/tex] shows the exponential growth rate of 7%

Answer:
15. d) 36
16. b) 20
17. d) 180
18. b) 50
19. c) 360
20. b) 60
Step-by-step explanation:
To find the number of sides a polygon has giving an interior angle, use the equation:
(number of sides - 2)*180/(number of sides) = measure of interior angle
15. (n = number of sides)
((n-2)*180)/n = 170
180n-360 = 170n
10n = 360
n = 36 (d)
16. (n = number of sides)
((n-2)*180)/n = 162
180n-360 = 162n
18n = 360
n = 20 (b)
17. The sum of the interior angles of a triangle is always 180 (d)
18. 180-60-70 = 50 (b)
19. The sum of the interior angles of a quadrilateral is always 360 (c)
20. 360-120-90-90 = 60 (b)
Triangles S T U and W V X are congruent. Angles W and W are congruent, T and V are congruent, and U and X are congruent. Which of the following statements are correct based on the diagram? Select all that apply. Segment U T is congruent to segment X V Angle S is congruent to angle V Segment S T is congruent to segment W V Angle V is congruent to angle T Segment U S is congruent to segment X V
The correct option will be that S T is congruent to segment W V.
Congruent trianglesGiven the triangles STU and WVX, if the triangje are congruent, then the measure of their sides will be the same.
Since the corresponding angles are congruent, hence the equivalent sides will be:
ST = WV
Su = WX
TU = VX

The last time I posted this question some random person took the points so DONT DO IT AGAIN (YOU KNOW WHO YOU ARE)Write the equation of a line in slope-intercept form with a slope of 10 and passes through (–4, – 25).
Answer:
[tex]y=10x+15[/tex]
Step-by-step explanation:
We want the equation of a line with a slope of 10 and passes through (-4, -25).
We can use the point-slope form given by:
[tex]y-y_1=m(x-x_1)[/tex]
Where m is the slope and (x₁, y₁) is a point.
So, we will substitute 10 for m and (-4, -25) for (x₁, y₁):
[tex]\displaystyle y-(-25)=10(x-(-4))[/tex]
Simplify:
[tex]y+25=10(x+4)[/tex]
Distribute:
[tex]y+25=10x+40[/tex]
Subtract 25 from both sides:
[tex]y=10x+15[/tex]
And we have our equation.

Answer:
Around 72.8 inches
Step-by-step explanation:
We are given the infomation that Chris is 185 centimeters tall.
There are 2.54 centimeters in an inch.
185/2.54 = 72.8346 ≈ 72.8
Chris should be around 72.8 inches.
Hope this helps.

Answer:
1. d ≈ 19
2. a ≈ 39.00°
3. x ≈ 37°
Step-by-step explanation:
1) Using sine to find d, recall that sine = opposite side/hypotenuse. So:
[tex]sin(39) = \frac{d}{30}[/tex]
Cross multiply:
d = 30 (sin(39))
d ≈ 19
2) To find the measure of the angle, we can use sine because we have the opposite side and hypotenuse measures. So:
[tex]sin(a) = \frac{18.88}{30}[/tex]
Using the inverse of sine:
[tex]a = sin-1(\frac{18.88}{30})[/tex]
Input into calculator:
a ≈ 39.00°
3) To find the measure of the angle, we can use tangent because we have the opposite side and adjacent side measures. So:
[tex]tan(x) = \frac{300}{400}[/tex]
Using inverse of tangent:
[tex]x = tan-1 (\frac{300}{400})[/tex]
Input into calculator:
x ≈ 37°
What is the equation of the line that is perpendicular to y=1/5x+4 and that passes through (5,—4)?
=========================================================
Work Shown:
The given equation y = (1/5)x+4 is in the form y = mx+b with m = 1/5 as the slope.
Apply the negative reciprocal to this slope to go from 1/5 to -5/1 or -5.
The original slope is 1/5 and the perpendicular slope is -5. Note the two slopes multiply to -1. This applies to any pair of perpendicular lines as long as neither line is vertical.
---------
We'll use m = -5 as the slope and (x,y) = (5,-4) to find the y intercept
y = mx+b
-4 = -5*5+b
-4 = -25+b
-4+25 = b
21 = b
b = 21
The y intercept of the perpendicular line is b = 21
With m = -5 and b = 21, we go from y = mx+b to y = -5x+21 which is the equation of the perpendicular line.

Answer:
33/20
Step-by-step explanation
$0.2 + $x = %1.36
20 IB + 80 IB = 100 IB
Equation: 0.2*20+x*80=1.36*100
there fore the answer is 33/20
The cost of 1 lb of sugar candies is $1.65.

3(7 – 2y) = 9
Please help. You have to solve it using distributive property. Thank you.
Answer:
3(7-2y)=9
Because there is no symbol between the 3 and the "(" we can tell that it wants you to multiply.
With the distributive property you must distribute the 3 within (7-2y)
To that you would multiply 7 by 3, and multiply -2y by 3. This would get you:
21-6y=9
To get y you must isolate it, the first step to isolate it is remove the number with no "y" next to it. Which is "21" Also for further problems your way, You should add/subtract/divide/multiple the number that does not have the same or even a variable as the variable you are trying to find to the other side.
In this case it would be subtracting 21 from the left side and subtracting it to the right side which would give us: 6y=-12
(Because there was already a number with no variable: "9" you will subtract 21 from 9 which is why you get -12).
Next you will further isolate the y by removing the -6. "-6y" means -6 multiplied by y. So you will divide -6 from the left side AND the right side.
-6y ÷ -6 = y ; -12 ÷ -6 = 2
y=2
More tips: When you are moving something to the other side always do the opposite to remove it from one side and move it to the other. Example: -12 + y = 5
You want to move the -12 to the right side. So you need to remove "-12" from the left side by ADDING 12 because -12 + 12 = 0.
Now you simply add it to the right.
Another example: 4y = 8
Because 4y is multiplication (4 times y) you must divide it from each side to isolate the y! : y=2
If you divide a number from the left side, you must also divide it from the right side. If you add a number on the left side, you must also add it on the right side. Same goes for subtraction and multiplication. Think like that!

Which value, when placed in the box, would result in a system of equations with infinitly many solutions? Y=2x - 5 2y-4x=
Given:
The system of equations is
[tex]y=2x-5[/tex]
[tex]2y-4x=?[/tex]
To find:
The missing value for which the given system of equations have infinitely many solutions.
Solution:
Let the missing value be k.
We have,
[tex]y=2x-5[/tex]
[tex]2y-4x=k[/tex]
Taking all the terms on the left side, the given equations can be rewritten as
[tex]-2x+y+5=0[/tex]
[tex]-4x+2y-k=0[/tex]
The system of equations [tex]a_1x+b_1y+c_1=0[/tex] and [tex]a_2x+b_2y+c_2=0[/tex] have infinitely many solutions if
[tex]\dfrac{a_1}{a_2}=\dfrac{b_1}{b_2}=\dfrac{c_1}{c_2}[/tex]
We have,
[tex]a_1=-2,b_1=1,c_1=5[/tex]
[tex]a_2=-4,b_2=2,c_2=-k[/tex]
Now,
[tex]\dfrac{-2}{-4}=\dfrac{1}{2}=\dfrac{5}{-k}[/tex]
[tex]\dfrac{1}{2}=\dfrac{1}{2}=\dfrac{5}{-k}[/tex]
[tex]\dfrac{1}{2}=\dfrac{5}{-k}[/tex]
On cross multiplication, we get
[tex]-k=10[/tex]
[tex]k=-10[/tex]
Therefore, the missing value is -10.
