Actually Welcome to the concept of expo functions.
f(x) = -8(2)^x - 12 ,
for f(0) ,here substitute x = 0
so we get as ,
==> f(0) = -8(2)^0 -12
==> f(0) = -8-12
==> f(0) = -20
hence, f(0) = -20
Answer:
Step-by-step explanation:
If it went from f(x) ⟹ f(0), that means that x=0.
So, you would plug in 0 for x in f(x)=-8(2)^x-12.
After plugging in the value of x, x=0, into the equation, you should have
f(0)=8(2)^0-12
Now, we are solving for f(0) (or f(x)).
You would use PEMDAS to solve this:
P-PARENTHESIS
E-EXPONENT
M-MULTIPLICATION
D-DIVISION
A-ADDITION
S-SUBTRACTION
There are no parenthesis
there are exponents,
(2)^0 and that =1
so we have f(0)=8(1)-12
there is multiplication, 8(1) which =8
so now we have f(0)=8-12
there is no division
there is subtraction
8-12, which equals -4
f(0)=-4
The first 4 terms of the sequence defined by the rule f(n) = 4n^2 + 4
Answers
Answer:
[tex]f(n) = 4n^2 + 4[/tex]
f(1) = 4 x 1 + 4 = 4 + 4 = 8
f(2) = 4 x 4 + 4 = 16 + 4 = 20
f(3) = 4 x 9 + 4 = 36 + 4 =40
f(4) = 4 x 16 + 4 = 64 + 4 = 68

The center of a circle is (3, 2) and a point on the circle is (5, -2). Find the radius and write the equation for the circle.
Answers
Answer:
r = [tex]2\sqrt{5}[/tex]
[tex](x - 3)^{2} + ( y - 2)^{2} = 20[/tex]
Is this a live test question or a homework question?
Step-by-step explanation:
the radius is the distance between (3, 2) and (5, -2)
[tex]r^{2}[/tex] = [tex]{(3 - 5)^{2} + (2 + 2)^{2} }[/tex]
= [tex](-2)^{2} + 4^{2}[/tex]
= 4 + 16 = 20
r = [tex]\sqrt{20 } = 2\sqrt{5}[/tex]
Equation of circle: [tex](x - 3)^{2} + ( y - 2)^{2} = 20[/tex]
Answer:
Radius: [tex]2\sqrt{5}[/tex]
Equation of circle: [tex](x-3)^2+(y-2)^2=20[/tex]
Step-by-step explanation:
The radius of a circle is equal to the distance between the center of the circle and any point on the circle. Therefore, we have:
[tex]r=\sqrt{(5-3)^2+(2-(-2))^2},\\r=\sqrt{2^2+4^2},\\r=\sqrt{20}=\boxed{2\sqrt{5}}[/tex]
The equation of a circle with radius [tex]r[/tex] and center [tex](h, k)[/tex] is given by:
[tex](x-h)^2+(y-k)^2=r^2[/tex].
What we know:
radius of [tex]2\sqrt{5}[/tex] center at [tex](3, 2)[/tex]Substituting known values, we get:
[tex](x-3)^2+(y-3)^2=(2\sqrt{5})^2,\\\boxed{(x-3)^2+(y-2)^2=20}[/tex]

The product of two rational number is 7. If one of the number
is 12, Find the other national number
Answers
Answer:
7/12 OR 0.58 (2.d.p)
Step-by-step explanation:
Product means that the two rational numbers are being multiplied to get 7.
The question also tells us that one of them is 12. Therefore we can write an equation to express this information where we represent the unknown rational number using the letter 'r':
r x 12 = 7
Rearrange to find r:
r x 12 / 12 = 7 /12
r = 7/12 = 0.5833....
= 0.58 (2.d.p)
Hope this helped!
Answer:
[tex]y = \frac{7}{12}[/tex]
Step-by-step explanation:
x × y = 7
We are given x = 12.
12 × y = 7
Rearrange.
y × 12 = 7
Divide each side by 12.
y × 12 ÷ 12 = 7 ÷ 12
Simplify.
[tex]y = \frac{7}{12}[/tex]

Answer:
c = 3
Step-by-step explanation:
Given
[tex]\frac{2}{c-2}[/tex] - [tex]\frac{3}{c+2}[/tex] = [tex]\frac{7}{c^2-4}[/tex] ← factor the difference of squares
[tex]\frac{2}{c-2}[/tex] - [tex]\frac{3}{c+2}[/tex] = [tex]\frac{7}{(c-2)(c+2)}[/tex]
Multiply through by (c - 2)(c + 2) to clear the fractions
2(c + 2) - 3(c - 2) = 7 ← distribute and simplify left side
2c + 4 - 3c + 6 = 7
- c + 10 = 7 ( subtract 10 from both sides )
- c = - 3 ( multiply both sides by - 1 )
c = 3

What is
3% of [(-0.5) * (- :)]
?
Answers
0.5:3*100 =
(0.5*100):3 =
50:3 = 16.666666666667
Now we have: 0.5 is what percent of 3 = 16.666666666667
Question: 0.5 is what percent of 3?
Percentage solution with steps:
Step 1: We make the assumption that 3 is 100% since it is our output value.
Step 2: We next represent the value we seek with $x$x.
Step 3: From step 1, it follows that $100\%=3$100%=3.
Step 4: In the same vein, $x\%=0.5$x%=0.5.
Step 5: This gives us a pair of simple equations:
$100\%=3(1)$100%=3(1).
$x\%=0.5(2)$x%=0.5(2).
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
$\frac{100\%}{x\%}=\frac{3}{0.5}$
100%
x%=
3
0.5
Step 7: Taking the inverse (or reciprocal) of both sides yields
$\frac{x\%}{100\%}=\frac{0.5}{3}$
x%
100%=
0.5
3
$\Rightarrow x=16.666666666667\%$⇒x=16.666666666667%
Therefore, $0.5$0.5 is $16.666666666667\%$16.666666666667% of $3$3.

Can someone help me calculate the ✨surface area✨ for this prism ?
I'm not even sure if I understand the formula "(
Answers
Answer:
216 cm^2.
Step-by-step explanation:
Surface area = 2 * area of triangular sides + area of 3 rectangles
= 2 * 1/2 * 6 * 8 + 8*7 + 6 * 7 + 10*7
= 48 + 56 + 42 + 70
= 216.
Answer:
216cm^2
Step-by-step explanation:
The surface area is equal to the sum of areas of the walls.
We've got 2 triangular walls with area 6*8/2, for 6*8 = 48cm^2 total
We've got a wall with 7x10 = 70cm^2
We've got a wall with 6x7 = 42cm^2
And the last wall is 8x7 = 56cm^2
So total surface area is: 48 + 70 + 42 + 56 = 216
