(a) The value of the function after 2 minutes later will be [tex]H=(T)^{t+2}[/tex].
(b) The value of the function at 15 F will be [tex]H=(15)^t[/tex].
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the function H =f(t) gives the temperature, HF, of an object t minutes after it is taken out of the refrigerator and left to sit in a room.
(a) The value of the function after 2 minutes will be,
[tex]H=T^t\\H=(T)^{t+2}[/tex]
(b) The value of the function at 15 F will be,
[tex]H=(15)^{t}[/tex]
Therefore, the value of the function after 2 minutes later will be [tex]H=(T)^{t+2}[/tex]. The value of the function at 15 F will be [tex]H=(15)^t[/tex].

Which shows a correct set of steps for adding 614 and 3516?
Answer:
Option A
Step-by-step explanation:
The unit volume explains it all.
Volumes are measured in units of length cubed. This also is the volume occupied by unit cubes.
By unit cubes, I meant, view the photo above
The volume of an object's says, how many of these cubes will fill that object.
It may not necessarily by a whole number.
So, the answer is Option A

Nancy goes to the Post Office to exchange money.
Exchange Rates
£1:$1.31
£1 : €1.14
*Commission Charged
$ £ €
Nancy changes $759.80 and €342 into pounds sterling.
The Post Office deducts their commission and gives Nancy £827.20
What is the percentage commission?
Answer:
6% commission
Step-by-step explanation:
Exchange Rates
£1:$1.31
£1 : €1.14
$759.80 to pounds sterling :
£1 = $1.31
x = $759.80
Cross multiply :
x = 759.80 / 1.31
x = £580
£1 = €1.14
x = €342
Cross multiply :
x = 342 /1.14
x = £300
Total = £(580 + 300) = £880
Amount deducted = commision = £880 - £827.20 = £52.80
Percentage commission :
(52.80 / 880) * 100%
0.06 * 100%
= 6% commission

Which is an example of a quadratic function whose graph opens downward and has its vertex at (0, 1)?
A. y = −x^2 + 1
B. y = x^2 + x − 1
C. y = x^2 + 4x + 1
D. y = x^2 − 1
Given:
The graph of a quadratic function opens downward and has its vertex at (0, 1).
To find:
The quadratic function.
Solution:
The vertex form of a quadratic function is:
[tex]y=a(x-h)^2+k[/tex] ...(i)
Where, a is a constant and (h,k) is the vertex.
If a<0, then graph opens downward and if a>0, then graph opens upward.
It is given that the quadratic function opens downward and has its vertex at (0, 1). It means a must be negative.
Putting h=0 and k=1 in (i), we get
[tex]y=a(x-0)^2+1[/tex]
[tex]y=ax^2+1[/tex]
For [tex]a=-1[/tex],
[tex]y=(-1)x^2+1[/tex]
[tex]y=x^2+1[/tex]
So, option A is correct.
In other options the leading coefficient is positive it means their graphs open upward. So, options B, C and D are incorrect.
Therefore, the correct option is A.

Answer:
1A. acute. all of the angles are under 90%. acute is under 90%, right is 90%, and obtuse is over 90%
2A. scalene. isosceles is all sides are the same length, and equilateral is all sides are the same length AND all the angles are 60%. with scalene all sides can be different lengths, and angles can be different
3. no. the rule for making a triangle is that any 2 sides added up, must be more than the 3rd side. so 6+2, 6+4 work, but 2+4 is 6, which is not greater than 6, the third side

how do you write 3,901.25 as a scientific notation?
Answer: 3.90125×10⁻³
Step-by-step explanation:
The scientific notation consists of two parts
the number based: a, where 0<a<10the exponent based: 10ˣ, which is determined by how we change the number based "a"So the final version should be: a×10ˣ
-------------------------------------------------------------------
STEP ONE. Number based
We are given 3,901.25
In order to make it within the range of a, we should move the decimal to the left three places, or divide the number by 10³, which is times 10⁻³
We get 3.90125
STEP TWO: Exponent based
Since we changed the number by 10⁻³, this will be our exponent-based.
Therefore, it is 3.90125×10⁻³
Hope this helps!! :)

In square units, what is the area of the blue sector in the figure above? Round to the nearest tenth.
Given:
A figure of a circle with radius 8. The central angle of the blue sector is 60 degrees.
To find:
The area of the blue sector.
Solution:
Area of a sector is:
[tex]A=\pi r^2\dfrac{\theta}{360^\circ}[/tex]
Where, r is the radius and [tex]\theta [/tex] is the central angle of the sector in degrees.
Putting [tex]r=8, \theta=60^\circ, \pi=3.14[/tex], we get
[tex]A=(3.14)\cdot (8)^2\cdot \dfrac{60^\circ}{360^\circ}[/tex]
[tex]A=(3.14) \cdot (64)\cdot \dfrac{1}{6}[/tex]
[tex]A=33.49333....[/tex]
Approximate the value to the nearest tenth.
[tex]A\approx 33.5[/tex]
Therefore, the area of the blue sector is about 33.5 sq. units.

Cash Orcheck had a balance of $867 in his checking account on
January 1. During January, Cash wrote checks for the following
amounts: $98. $456, $29, and $381. What was his balance at the
end of January?
Answer:
Well since he wrote the amount, he’s technically giving cash away so you basically jsut add everything.
98+456+29+381= 964
867-964= -97
His final balance would be -97
Here’s the thing, a checking account acts like a debit card. Its your own cold hard cash. That means you can’t give away more then you have.
So here are the two options
1) At least one or at most 2 checks must’ve bounced
2) He got more money in his checking account
