Answer for the first box = -31.67
Answer for the second box = 17.22
===============================================
Work Shown:
Plug in F = -25 and solve for C
F = (9/5)C+32
-25 = (9/5)C + 32
(9/5)C + 32 = -25
(9/5)C = -25-32 ... subtract 32 from both sides
(9/5)C = -57
C = (5/9)*(-57) ... multiply both sides by 5/9, its the reciprocal of 9/5
C = -31.667 approximately
C = -31.67 rounding to 2 decimal places
This shows that -25 degrees F converts to roughly -31.67 degrees C.
-----------------
Repeat the same basic steps, but now use F = 63
F = (9/5)C+32
63 = (9/5)C+32
(9/5)C+32 = 63
(9/5)C = 63-32
(9/5)C = 31
C = (5/9)(31)
C = 17.222 approximate
C = 17.22
----------------
If the temperature ranges from -25 degrees F to 63 degrees F, then this converts to the range of roughly -31.67 degrees C to 17.22 degrees C

Answer:
This is not a function.
Step-by-step explanation:
A function by definition will map one element of the domain to one element of the range. In this example, we would need one element of A to match one element of B for all elements of A.
Note, there are two elements in set A that map to one element in set B, while one element in set B has no mapping from any element in set A.

Answers
Answer:
(See explanation below for further details)
Step-by-step explanation:
A second order polynomial (quadratic function) can be well represented with at least three distinct points. Let is take five equidistant different points:
x = 0
[tex]f(0) = 3\cdot (0)^{2}-8\cdot (0) +2[/tex]
[tex]f(0) = 2[/tex]
x = 1
[tex]f(1) = 3\cdot (1)^{2}-8\cdot (1)+2[/tex]
[tex]f(1) = -3[/tex]
x = 2
[tex]f(2) = 3\cdot (2)^{2}-8\cdot (2)+2[/tex]
[tex]f(2) = -2[/tex]
x = 3
[tex]f(3) = 3\cdot (3)^{2}-8\cdot (3)+2[/tex]
[tex]f(3) = 5[/tex]
x = 4
[tex]f(4) = 3\cdot (4)^{2}-8\cdot (4) + 2[/tex]
[tex]f(4) = 18[/tex]

The number of birds (b) in a park increases when the number of dogs in the park (d) decreases. Write the correct equation for this scenario, and solve for the number of birds when there are 10 dogs.
Answers
Complete question :
The number of birds (b) in a park increases when the number of dogs in the park (d) decreases. Write the correct equation for this scenario, and solve for the number of birds when there are 10 dogs.
Dogs(d) - - birds(b)
40 - - - - - - 10
50 - - - - - - 8
Answer:
b = k/d ; 40
Step-by-step explanation:
From the table:
Dogs(d) - - birds(b)
40 - - - - - - 10
50 - - - - - - 8
The number of birds(b) in a park increases when the number of dogs (d) decreases.
Hence we can infer that an inverse relationship exists between them.
Number of birds(b) ∝ 1 / number of birds
b ∝ 1 / d
b = k/d
k = (b × d)
Where k is the proportionality constant
When d = 40, b = 10
Solve for k
k = (40 * 10)
k = 400
Therefore, number of birds(b), when there are 10 dogs;
b = k/d
k = 400, d = 10
b = 400 / 10
b = 40
40 birds when dogs = 10

[tex] \boxed{ \bold{ \sf{Vat \: amount = \: \: Rs \: 768.3}}}[/tex]
Step-by-step explanation:
Given,
Marked Price ( MP ) = Rs 6000
Vat percent = 13 %
Discount percent = 15%
▪️Finding the discount amount
Discount amount = Discount % of MP
= 15 % of 6000
= Rs 900
▪️Finding the selling price
Selling price ( SP )= Marked price - Discount amount
= Rs 6000 - Rs 900
= Rs 5910
▪️Finding the vat amount
Vat amount = Vat % of SP
= 13 % of 5910
= Rs 768.3
▪️Finding SP with VAT
SP with vat = SP + vat amount
= Rs 5910 + Rs 768.3
= Rs 6678.3

Divide 98 by 3
so, we have the following representation
Quotient = 32
Next, we have
Remainder = 98 - 32 * 3
Evaluate the products
Remainder = 2

Answers
Explanation:
The coefficient is the number just to the left of the variable. So that's why -8 is the coefficient for -8x. This is the variable term while 15 is the constant (it has no variable multiplied with it). The two terms are 15 and -8x since we can write 15-8x as 15+(-8x). Terms are separated by a plus sign.

Express the interval set builder notation
Answers
Answer:
{x | -1 < x ≤ 2}
Step-by-step explanation:
Interval given in the notation of (a, b) denotes,
Upper limit at 'b' and lower limit at 'a'
Sign () denotes the interval between a and b exclusive of the numbers a and b.
Interval given as [a, b] represents,
a = lower limit
b = higher limit
Notation of [] show the interval inclusive of these numbers.
Given set in the question is (-1, 2]
Here (-1) is the lower limit and 2 is the upper limit.
(] notation shows exclusive of (-1) and inclusive of 2.
Therefore, solution set in set-builder notation will be {x | -1 < x ≤ 2}
