Answer:
≈4715.56
Step-by-step explanation:
The value of the quantity after one day to the nearest hundredth will be 4715.56.
What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Given that:-
A quantity with an initial value of 5500 decays exponentially at a rate of 5% every eight hours what is the value of the quantity after one day to the nearest hundredthThe expression for the final value will be:-
Final quantity = 5500( 0.95 )³
Final quantity = 4715.56
Therefore the value of the quantity after one day to the nearest hundredth will be 4715.56.

An equitorial triangle has 3 medians true or false
Note: Its equilateral not equitorial triangle .
Given:
The statement is "An equilateral triangle has 3 medians".
To find:
Whether the given statement is true or false.
Solution:
Median of a triangle connected the vertex and midpoint of opposite side of the triangle.
We know that that every triangle has three medians.
In case of equilateral triangle, all sides and angles are equal and median is the height of the triangle.
So, an equilateral triangle has 3 medians.
Therefore, the given statement is true.

What is f(0) if f(t) = t^2 – 2t – 2?
Answer:
-2
Step-by-step explanation:
f(t) = t^2 – 2t – 2
To find f(0), replace t with 0 in the expression and evaluate the expression.
f(0) = 0^2 – 2(0) – 2
f(0) = -2
0 = t
We know this because 0 replaced t in the parenthesis next to F !
The question is just asking you to plug in 0 where ever t is!
Let's do it
[tex]f(0) = 0^{2} - 2(0) - 2[/tex]
solve
[tex]0^{2} = 0 \\2 ( 0 ) = 0[/tex]
so, this is what we have left!
[tex]f(0) = 0 - 0 - 2[/tex]
We have our answer!
[tex]f (0) = -2[/tex]

Kate and Nora each have a sum of money. The ratio of the amount of money Kate has to that of Nora is 3 : 5. After Nora gives $150 to Kate, the ratio of the amount of money Kate has to that of Nora becomes 7 : 9. Find the sum of money Kate had initially.
Given:
The ratio of the amount of money Kate has to that of Nora is 3 : 5.
After Nora gives $150 to Kate, the ratio of the amount of money Kate has to that of Nora becomes 7 : 9.
To find:
The sum of money Kate had initially.
Solution:
Let the initial amount of money Kate and Nora have are 3x and 5x respectively.
After Nora gives $150 to Kate, the ratio of the amount of money Kate has to that of Nora becomes 7 : 9.
The amount of Kate = 3x+150
The amount of Nora = 5x-150
Now,
[tex]\dfrac{3x+150}{5x-150}=\dfrac{7}{9}[/tex]
[tex]9(3x+150)=7(5x-150)[/tex]
[tex]27x+1350=35x-1050[/tex]
[tex]1350+1050=35x-27x[/tex]
[tex]2400=8x[/tex]
Divide both sides by 8.
[tex]300=x[/tex]
Putting x=300 in 3x, to get the amount of money Kate has initially.
[tex]3(300)=900[/tex]
Therefore, the Kate initially had $900.
The sum of the first five terms of an arithmetic sequence is 35. The sum of the next five terms is 85. Determine the first term and the common difference of the sequence.
Answer:
The first term is 3 and the common difference is 2
Step-by-step explanation:
The formula of the sum of the nth term of the arithmetic sequence is
[tex]S_{n}=\frac{n}{2}[2a+(n-1)d][/tex], where
a is the first termd is the common differencen is the position of the term∵ The sum of the first five terms of an arithmetic sequence is 35
∴ [tex]S_{5}[/tex] = 35
→ Substitute The values of n and S in the rule above
∵ 35 = [tex]\frac{5}{2}[2a+(5-1)d][/tex]
∴ 35 = [tex]\frac{5}{2}[2a+4d][/tex]
→ Simplify the right side
∴ 35 = 5a + 10d
→ Switch the two sides
∴ 5a + 10d = 35 ⇒ (1)
∵ The sum of the next five terms is 85
→ To find the sum of the first 10 terms add 85 to [tex]S_{5}[/tex]
∴ [tex]S_{10}[/tex] = 35 + 85 = 120
→ Substitute The values of n and S in the rule above
∵ 120 = [tex]\frac{10}{2}[2a+(10-1)d][/tex]
∴ 120 = 5[2a + 9d]
→ Simplify the right side
∴ 120 = 10a + 45d
→ Switch the two sides
∴ 10a + 45d = 120 ⇒ (2)
Now we have a system of equations to solve it and find a and d
→ Multiply equation (1) by -2
∵ -2(5a) + -2(10d) = -2(35)
∴ -10a + -20d = -70 ⇒ (3)
→ Add equations (2) and (3)
∵ (10a + -10a) + (45d + -20d) = (120 + -70)
∴ 25d = 50
→ Divide both sides by 25 to find d
∴ d = 2
→ To find a substitute d in equation (1) by 2
∵ 5a + 10(2) = 35
∴ 5a + 20 = 35
→ Subtract 20 from both sides
∵ 5a + 20 - 20 = 35 - 20
∴ 5a = 15
→ Divide both sides by 5
∴ a = 3
∴ The first term is 3 and the common difference is 2
The slide at a playground
has a height of 22 feet. The
distance between the foot
of the ladder and the end of
the slide is 10 feet. What is
the length of the slide?
Round to the nearest tenth.
Answer:
c = 24.17 feet
Step-by-step explanation:
Right Triangles
A right triangle is a special triangle that has an interior angle of 90°.
In right triangles, Pythagora's Theorem is satisfied:
[tex]c^2=a^2+b^2[/tex]
Where c is the hypotenuse (longest side) of the triangle, and a and b are the legs or the smaller sides.
The slide can be thought of as a right triangle whose hypotenuse is the slide itself and the legs are the height of the ladder and distance between the foot of the ladder and the end of the slide.
So we have:
[tex]c^2=22^2+10^2[/tex]
[tex]c^2=484+100=584[/tex]
[tex]c=\sqrt{584}[/tex]
c = 24.17 feet
area of a rectangle whose length is 4x-6 and width is x+1
Answer: The area is 4x^2-2x-6
Step-by-step explanation: The area of a rectangle is length*width. So multiply both these terms. Remember the method foil, that would apply here. (4x-6)(x+1), you end up with 4x^2+4x-6x-6. Then combine like terms, to get 4x^2-2x-6.

What is the equation of this line in slope intercept forn?
3z +y=2
A. y=-3+2
B. y=3z +2
C. y=-3z 2
D. y=3r-2
Answer:
We conclude that the equation of this line in the slope-intercept form will be:
[tex]y = -3z+2[/tex]Step-by-step explanation:
We know that the slope-intercept form of the line equation is
[tex]y=mx+b[/tex]
where m is the slope and b is the y-intercept.
Given the equation
[tex]3z +y=2[/tex]
Writing the equation in the slope-intercept form of the line equation by simplifying it
subtracting 3z from both sides
[tex]3z+y-3z = -3z+2[/tex]
[tex]y = -3z+2[/tex]
Therefore, we conclude that the equation of this line in the slope-intercept form will be:

Find the average rate of change for f(x)= x² + 3x - 6 for x₁
: 1 to 2 = 3
The average rate of change for f(x)=3x²-3 from x =1 to x=2 is 6.
What is the average rate of change?
The average rate of change is the rate at which the value of function changed per unit of independent variable over a given interval. Let f(x) be a function and value of x changes from x₁ to x₂ then rate of change of f(x) over the interval (x₁, x₂ ) is
[f(x₂)-f(x₁)]/[x₂-x₁]
Average rate of change = [f(x₂)-f(x₁)]/[x₂-x₁]
Given function is
f(x)=3x²+3x-6
x changes from 1 to 2
Then average rate of change for f(x) is [tex]\frac{f(2)-f(1))}{2-1}[/tex]
[tex]f(2)=2^{2} +3(2)-6=4+6-6\\\\f(2)=4\\f(1)=1^{2}+3(1)-6 =1+3-6\\f(1)=-2[/tex]
