Answer:

12, 36, 108, 324

Step-by-step explanation:

using the recursive formula and a₁ = 4 , then

a₂ = 3a₁ = 3 × 4 = 12

a₃ = 3a₂ = 3 × 12 = 36

a₄ = 3a₃ = 3 × 36 = 108

a₅ = 3a₄ = 3 × 108 = 324

Answer:

x=73

Step-by-step explanation:

The two angles are equivalent, therefore x=73

I believe Alia because she read 2.5/3 of the book and Zarius only read 3/4 of the book altogether.

Step-by-step explanation:

Z; 4/8=1/2 or 2/4 +1/4=3/4

A: 1/2=3/6+2/6= 5/6 if you divide that by 2 then she read 2.5/3 of her book

in then end 3rds are greater then fourths

Answer:

9 packs

Step-by-step explanation:

Step 1: Divide the number of pencils by the single pack that they came in.

216/24 = 9

Therefore, Ms. Weaver bought 9 packs for her class.

Verify: 9(24) = 216

Answer:

a)

Step-by-step explanation:

The y-intercept is when x = 0.

[tex]a^0=1[/tex], therefore when x = 0, y = 10

So the y-intercept is (0, 10)

The curve approaches the x-axis in quadrant 2, increases, passes through (0, 10) to quadrant 1 (see attached graph)

to isolate the m you would add 11 to each side to cancel out -11 so m=37

Answer:

total profit = $428,517,224  (nearest whole number)

Step-by-step explanation:

Use geometric sum formula:

[tex]S_n=\dfrac{a(1-r^n)}{1-r}[/tex]

where [tex]a[/tex] is the initial value and [tex]r[/tex] is the common ratio

We have been told that the initial value is 242500, so [tex]a=242500[/tex].

If the company's profit increases by 22% per year, this means each year's profit is 122% of the previous year's profit. 122% = 122/100 = 1.22

Therefore, [tex]r = 1.22[/tex]

We need to calculate the total profit earned over 30 years, so [tex]n = 30[/tex]

Inputting these values into the formula:

[tex]\implies S_{30}=\dfrac{242500(1-1.22^{30})}{1-1.22}=\$428,517,224 \ \textsf{(nearest whole number)}[/tex]

1/2-1/4

Find its LCM which would be 4

So change the 1/2 to 2/4 and keep 1/4 the same since we already have the denominator we need so

2/4-1/4 = 1/4

Answer:  15/13

Step-by-step explanation:

Answer:

The profit increases from day 0 to day 8 after the strawberries first ripen.

Step-by-step explanation:

A function is increasing when the slope is positive (y gets bigger as x gets bigger).

A function is decreasing when the slope is negative (y gets smaller as x gets bigger).

From inspection of the graph, we can see that the maximum point is (8, 6000), so the maximum profit of $6,000 occurs on day 8.

The slope of the curve is increasing as the curve approaches the maximum point, so the profit is increasing during this time period.

Therefore, the profit increases from day 0 to day 8 after the strawberries first ripen.

The slope of the curve is decreasing after the maximum point, so the profit is decreasing after 8 days.

The profit increases from 8 days after the first strawberries ripen.

Answer:

The triangle is a scalene obtuse triangle

Step-by-step explanation:

We have angles of 13, 104, and 63

Since all of the angles are different, all of the sides have different lengths, so the triangle is scalene

The largest angle is 104 degrees.  Since it is larger than 90 degrees, it is obtuse.

The triangle is a scalene obtuse triangle

Answer:

obtuse maybe

Step-by-step explanation:

I don't really know but let me know if you get it right.

Why I picked obtuse is because of 104 degrees normally obtuse angles have smaller degrees than there is 1 that is bigger number for instantance 104 or over 100 degrees.

Have a nice day! :)

Answer:

Domain: set of possible input values (x-values)

Range: set of output values (y-values)

The range for the function [tex]f(x)=-2|x-5|+8[/tex] is:

[tex]f(x)\leq 8[/tex]

(5, 8) is the vertex of the line

Because |x - 5| is absolute (so always positive) and it is multiplied by -2,

-2|x - 5| will always be negative unless x = 5 (when it will be zero).  Therefore, the max y-value is 8.

However, your question actually asked what the function is when x = -5:

[tex]f(-5)=-2|x-5|+8\\\\= -2|-5-5|+8\\\\= -12[/tex]

1i) 3m. 3 x m is the same as 3m

1ii) 2m + 15. 2 x m + 15 can be written as 2m + 15

Answer:

3m and 2m+15

Step-by-step explanation:

"three times m" = 3 multiplied by m = 3m

"15 more than twice the given number"

Twice the given number is 2m. 15 more than that is 2m+15.

Answer:

the value of x is 0

Step-by-step explanation:

you: thanks

Me: no problem :)

Answer:

4s

Step-by-step explanation:

Equate the equations and solve for x:

[tex]-3x^2 + 24x + 3=-4x^2 + 25x + 15[/tex]

[tex]\implies x^2 -x -12=0[/tex]

[tex]\implies x^2 -4x+3x -12=0[/tex]

[tex]\implies x(x-4)+3(x-4)=0[/tex]

[tex]\implies (x+3)(x-4)=0[/tex]

[tex]\implies x=-3, x=4[/tex]

As time is positive, x = 4

The time at which the water balloons collided at their highest point is 7 seconds after the launch.

To find the time at which the two water balloons collided at their highest point, we need to determine the time at which the sum of their heights is maximized. The sum of the heights is represented by the sum of the two quadratic functions.

Given the functions:

y = -3x² + 24x + 3

y = -4x² + 25x + 15

The sum of the heights, S(x), is:

S(x) = (-3x² + 24x + 3) + (-4x² + 25x + 15)

Combine like terms:

S(x) = -7x² + 49x + 18

To find the time when the sum of the heights is maximized, we need to find the x-coordinate of the vertex of the parabolic function S(x). The x-coordinate of the vertex of a quadratic function in the form ax² + bx + c is given by:

x vertex = -b / (2a)

In this case, for S(x) = -7x² + 49x + 18:

a = -7

b = 49

Calculate the x-coordinate of the vertex:

x vertex = -49 / (2 * -7)

x vertex = 7

Now that we have the x-coordinate of the vertex, we can find the corresponding time by plugging it into either of the original functions. Let's use the first function for simplicity:

y = -3x² + 24x + 3

When x = 7:

y = -3(7)² + 24(7) + 3

y = -147 + 168 + 3

y = 24

Therefore, the time at which the water balloons collided at their highest point is 7 seconds after the launch.

An exponential function can either represent population growth or population decay

The question is incomplete, as the resources to model the population of the Western Lowland Gorillas are not given.

However, the following is a general guide to solve the question.

An exponential function is represented as:

[tex]y=a(1 \pm r)^x[/tex]

Where:

Given that the population of the Western Lowland Gorillas decreases, then the rate of the function would be 1 -r (i.e. an exponential decay)

Take for instance:

[tex]y = 20000 * 0.98^x[/tex]

By comparison.

a = 2000 and 1 - r = 0.98

The above function can be used to model the population of the Western Lowland Gorillas

First note that [tex]A_n[/tex] means the nth term in the sequence.

1. First one is a simple arithmetic progression/sequence as the common differences between each two numbers are 1

So the sequence will be

1.) 2,3,4,5,6,7...

And the rule since its +1 each time will be

[tex]A_n=2+1*(n-1)[/tex]

For the nth term of the sequence.

2.This one can be seen as a simple geometric sequence as the common ratio between the number and the number after it is 1:2

So the sequence will be

2.)2,4,8,16,32,64

And the rule since it is *2 each time is a simple exponential function

[tex]A_n=2*2^{n-1}\\or\\A_n=2^n[/tex]

3.This one is tricky but it can be seen that the term is double the term before subtract 1

So the sequence will be

3.)5,9,17,33,65,129

And the rule based on this sequence will be

[tex]A_n=A_{n-1}*2-1[/tex]

**Please note that this rule specifically is written in recursive form as it is a lot more difficult otherwise.

4 This one is similar to problem 1 which is an arithmetic sequence this one just have a common differences of 3 instead of 1.

So the sequence will be

4.)25,28,31,34,37

And the rule based on the sequence will be

[tex]A_n=25+3*(n-1)[/tex]

Answer:

O A. PQ = SU

Step-by-step explanation:

When two triangles are congruent then by CPCTC,

their corresponding parts ( angles and sides )  must be congruent.

In triangles PQR and STU,

Side PQ, QR and RP are corresponding to the sides ST, TU and US respectively,

Also, angles P, Q and R are corresponding to angles S, T and U respectively.

Here, Δ PQR ≅ Δ STU,

Thus, by the above property,

PQ ≅ ST, QR ≅ TU and RP ≅ US,

∠P ≅ ∠T, ∠Q ≅ ∠T and ∠R ≅ ∠U
