Answer:
R = 17
Step-by-step explanation:
R = 2q - 5
Q = 3p + 2
Find the numerical value of R when p = 3
R = 2q - 5
R = 2(3p + 2) - 5
R = 6p + 4 - 5
R = 6p - 1
When p = 3
R = 6(3) - 1
R = 18 - 1
R = 17

A bouncy ball is dropped such that the height of its first bounce is 2.75 feet and each
successive bounce is 69% of the previous bounce's height. Write a recursive formula
to represent the height of the nth bounce of the ball.
The value 2.75 goes in the first box, since it's the first term.
The expression [tex]0.69*a_{n-1}[/tex] goes in the second box. The second line says "to get the nth term, we multiply the previous term by 0.69"
Please help me

What is the decay factor of the exponential function
represented by the table?
Given:
The table of values of an exponential function.
To find:
The decay factor of the exponential function.
Solution:
The general form of an exponential function is:
[tex]y=ab^x[/tex] ...(i)
Where, a is the initial value and [tex]0<b<1[/tex] is the decay factor and [tex]b>1[/tex] is the growth factor.
The exponential function passes through the point (0,6). Substituting [tex]x=0,y=6[/tex] in (i), we get
[tex]6=ab^0[/tex]
[tex]6=a(1)[/tex]
[tex]6=a[/tex]
The exponential function passes through the point (1,2). Substituting [tex]x=1,y=2,a=6[/tex] in (i), we get
[tex]2=6(b)^1[/tex]
[tex]2=6b[/tex]
[tex]\dfrac{2}{6}=b[/tex]
[tex]\dfrac{1}{3}=b[/tex]
Here, [tex]b=\dfrac{1}{3}[/tex] lies between 0 and 1. Therefore, the decay factor of the given exponential function is [tex]\dfrac{1}{3}[/tex].
Hence, the correct option is A.

Given JKMN is a square and NM= 4x and KM = 6x - 16, find all missing angle measures and side lengths.
Answer:
The side lengths are 32 units each
Step-by-step explanation:
Given
[tex]NM= 4x[/tex]
[tex]KM = 6x - 16[/tex]
Required
The side lengths and missing angles
Since JKMN is as square, then:
[tex]NM = KM[/tex] -- all sides are equal
[tex]4x = 6x - 16[/tex]
Collect like terms
[tex]4x - 6x = - 16[/tex]
[tex]-2 x = - 16[/tex]
Divide by -2
[tex]x = 8[/tex]
Substitute [tex]x = 8[/tex] in [tex]NM= 4x[/tex]
[tex]NM = 4 * 8[/tex]
[tex]NM = 32[/tex]
The missing angles can't be solved without an attachment.
However, if the missing angles are the angles at the edges of the square, then they measure 90 degrees each (i.e. angles at right angle)

What pair of angles must have the same measure?I'll give brainliest if its correct.
Answer:
[tex]\text{(C) }\angle 2\text{ and }\angle 7[/tex]
Step-by-step explanation:
Angle 2 corresponds with angle 6 and since all corresponding angles are equal, [tex]\angle 2=\angle 6[/tex]. Angle 6 and angle 7 happen to be vertical angles (opposite side of an intersection of two lines). Since all vertical angles are also equal, [tex]\angle 6=\angle 7[/tex] and by substitution, we have: [tex]\implies \boxed{\text{(C) }\angle 2\text{ and }\angle 7}[/tex]
Describe the behavior of the function h around its vertical asymptote at x=-6.

Step-by-step explanation:
One good way to look at this is to graph both polynomials, as shown in the picture. A tip to help graph is to factor it out and work from there. For example, in x²+14x+48, we can gather that (x+6)(x+8) is the same thing, and it is easier to then graph it. Similarly, for x²+12x+36, we can factor it out as (x+6)² .
When x²+12x+36 approaches 6, it is getting really close to 0, but it stays positive. When x²+14x+48 approaches 6 from the negative side, it is also getting close to 0, but it's negative. When x²+14x+48 approaches 6 from the positive side, it is positive.
Therefore, on the negative side, there is one positive and one negative (dividing a negative by a positive is negative, and a positive by a negative is also negative) , and on the positive side, there are two positives, forming one answer.The answer is therefore B
Which is the length of the building's wall brace?
A. 14.45 m
B. 17 m
C. 23 m
D. 49 m
E. 189 m
Answer:
A) 14.45 m is the answerrrerreer
Answer:
17m
Step-by-step explanation:
We can use the Pythagorean theorem
a^2+b^2= c^2 where a and b are the legs and c is the hypotenuse
8^2 + 15^2 = c^2
64+ 225 = c^2
289 = c^2
Taking the square root of each side
sqrt(289) = sqrt(c^2)
17 =c

Answer:
D
Step-by-step explanation:
For this one, you want to solve it similarly to linear equations.
-13x+11<-24x by adding 24x to both sides becomes 11x<11.
From there, you divide by 11 to isolate x, leaving x<1.
Since the equation has a < symbol (not ≤), the dot is not filled in. X is less than 1, so the arrow goes to the left, making it D.

The expression for the distance between two points is
d=√((x_2-x_1)²+(y_2-y_1)²)
substitute
d=√((4-(-7))²+(-3-5)²)
d=√((4+7))²+(-8)²)
d=√(11)²+(-8)²)
d=√121+64
d=√185
d=13.60units
Hence the distance is 13.60units
Karina and Kayla are playing a game using a dice. They roll the dice twice. If Kayla rolls a sum of 7, she scores a point. If Karina rolls a sum of 5, she scores a point. Is the game fair?
8x+20y=-120 as slope
Answer:
y = -2/5x -6
slope is -2/5
y intercept -6
Step-by-step explanation:
8x+20y=-120
Slope intercept form is y = mx+b where m is the slope and b is the y intercept
Subtract 8x from each side
8x -8x+20y= -8x-120
20y = -8x - 120
Divide by 20
20y/20 = -8x/20 -120/20
y = -2/5x -6
You invest $10,200 in an account that compounds continuously at an annual percent interest rate of 6.25%. How long does it take to double your money?
Answer:
11.09 years
Step-by-step explanation:
Given data
Principal P= $10200
Rate= 6.25%
Double the principal A = $20,400
The expression for the time taken is
t= ln(A/P)/r
t= ln(20400/10200)/0.0625
t= ln(2)/0.0625
t= 0.69314/0.0625
t= 11.09024 years
Hence the number of years is 11.09 years
