Answer:
[tex]\boxed {\boxed {\sf D. \ f(3)= 30}}[/tex]
Step-by-step explanation:
We are given the function:
[tex]f(x)= 3(2)^x+6[/tex]
We want to find f(3), so we must substitute 3 in for x.
[tex]f(3)= 3(2)^3+6[/tex]
Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction.
Solve the exponent first.
2³= 2*2*2= 4*2= 8[tex]f(3)= 3(8)+6[/tex]
Multiply 8 and 3.
[tex]f(3)= 24+6[/tex]
Add.
[tex]f(3)=30[/tex]
For the function given, f(3) is 30.

Find the measures of the numbered angles in rhombus ABCD.
Answer:
∠1=66⁰
∠2=24⁰
∠3=24⁰
∠4=90⁰
Step-by-step explanation:
∠2=∠ADB=24 (ΔADB is isosceles, so ∠ADB=∠ABD)
∠4 =90 (right angle)
∠3=24 (BD bisects ∠ABC, so ∠2=∠3)
∠1+∠2+90=180 (angles in triangle add to 180)
∠1=66

Answer:
(-1)^2+5= 1+5=6
(0)^2+5= 0+5= 5
(1)^2+5= 1+5= 6
6+5+6= 17
x-1 + x0 + x1 = (-1)^2 + 5 + (0)^2 + 5 + (1)^2 + 5 = 6 + 5 + 6 = 17

The bottom layer of a rectangular prism contains 15 unit cubes The prism is made up of 5 equal-size layers what is the volume of the prism in cubic units
Answer:
75 cubic units
Step-by-step explanation:
Bottom layer of a rectangular prism is made up of 15 unit cubes.
Therefore, area of the 15 unit cubes = 15(area of the base of one unit cube)
= 15(1)²
= 15 unit²
Number of layers of unit cubes in the rectangular prism = 5
So the height of the prism = 5 units
Volume of the prism = (Area of the base) × Height
= 15 × 5
= 75 cubic unit

If – 2/3X – 1 = 4, then x =
Answer:
2/5
Step-by-step explanation:
The value of x will be x = -15/2
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
We are given that the equation – 2/3X – 1 = 4
Here, we need to solve for x,
– 2/3X – 1 = 4
Now combine the like terms;
– 2/3X = 4 + 1
-2/3x = 5
x = -15/2
Therefore, the solution will be as;
x = -15/2
The value of x will be; x = -15/2

Aaron saw it was 86° Fahrenheit, F, in Australia in January. Aaron used the formula C=5/9(F−32) to find the temperature in degrees Celsius, C. What temperature, in degrees Celsius, did Aaron find?
Answer:
[tex]30^{\circ}\text{C}[/tex]
Step-by-step explanation:
The temperature that Aaron saw was [tex]86^{\circ}\text{F}[/tex]
The formula to convert Fahrenheit to Celsius is
[tex]C=\dfrac{5]{9}(F-32)[/tex]
[tex]\Rightarrow C=\dfrac{5}{9}\times (86-32)[/tex]
[tex]\Rightarrow C=30^{\circ}\text{C}[/tex]
The given temperature in Celsius that Aaron found would be [tex]30^{\circ}\text{C}[/tex].

find the 9th term of the geometric sequence 2, -10 50 -250
Answer:
781250
Step-by-step explanation:
We first need to find the common ratio
-10 /2 = -5
50 / -10 = -5
The common ratio is -5
an = a (r) ^ (n-1)
a9 = 2 ( -5) ^(9-1)
= 2 (-5)^8
=781250
