If f(x) is an exponential function where f(-2) = 1 and f(7) = 63, then find the
value of f(1), to the nearest hundredth.
Answers
An exponential function is represented as: [tex]\mathbf{f(x) = ab^x}[/tex]
The value of f(1) is 3.95
f(-2) = 1 means that:
[tex]\mathbf{ab^{-2} = 1}[/tex]
f(7) = 63 means that:
[tex]\mathbf{ab^{7} = 63}[/tex]
Divide both equations
[tex]\mathbf{\frac{ab^7}{ab^{-2}} = \frac{63}{1}}[/tex]
Apply law of indices
[tex]\mathbf{b^9 = 63}[/tex]
Take 9th root of both sides
[tex]\mathbf{b =1.58}[/tex]
Make a, the subject in [tex]\mathbf{ab^{-2} = 1}[/tex]
[tex]\mathbf{a = \frac{1}{b^{-2}}}[/tex]
[tex]\mathbf{a = b^2}[/tex]
Substitute [tex]\mathbf{b =1.58}[/tex]
[tex]\mathbf{a = 1.58^2}[/tex]
[tex]\mathbf{a = 2.50}[/tex]
So, we have:
[tex]\mathbf{f(x) = ab^x}[/tex]
[tex]\mathbf{f(x) = 2.50 \times 1.58^x}[/tex]
Substitute 1 for x
[tex]\mathbf{f(1) = 2.50 \times 1.58^1}[/tex]
[tex]\mathbf{f(1) = 3.95}[/tex]
Hence, the value of f(1) is 3.95

Find the measure of each marked angle.
Answers
Answer:
X= 15, m∠78°
Step-by-step explanation:
Since the angles are vertically opposite
Therefore their measurements are equal
Therefore (2x + 48 ) = (5x + 3 )
So,
[tex](2x + 48) = (5x + 3)\\(2x-5x)= (3-48)\\-3x = -45\\x = -45/-3\\x = 15[/tex]
[tex](2x + 48)\\=( 2* 15 + 48)\\= 30 + 48\\=78\\\\(5x + 3)\\=(5*15 + 3)\\=75+3\\=78[/tex]
They both equal 78°

KEEP: 180 - 30 because it helps solve for the x-value
6x = 180 - 30
180 - 30 = 150
NEW EQUATION: 6x = 150
DIVIDE 6 to BOTH SIDES
6x/6 P 150/6
CANCEL out: 150/6 because that gives you the result of the x-value

Second, how does that change were you are at this point?
ok so I start at (8, 9). I move left 5 units. Where do I end?
Since moving to the left changes my x variable, subtract 5 from 8
8 - 5 = 3
so that means my final position is at (3, 9)
