An exponential function f(x)
= ab" passes through the points (0, 12000) and (2, 3000). What are the values of a and b ?
Given:
An exponential function [tex]f(x)=ab^x[/tex] passes through the points (0, 12000) and (2, 3000).
To find:
The values of a and b.
Solution:
We have,
[tex]f(x)=ab^x[/tex] ...(i)
It passes through the point (0,12000). Putting x=0 and f(x)=12000 in (i), we get
[tex]12000=ab^0[/tex]
[tex]12000=a(1)[/tex]
[tex]12000=a[/tex]
Given function passes through the point (2,3000). Putting x=2, a=12000 and f(x)=3000 in (i), we get
[tex]3000=12000b^2[/tex]
[tex]\dfrac{3000}{12000}=b^2[/tex]
[tex]\dfrac{1}{4}=b^2[/tex]
Taking square root on both sides.
[tex]\pm \dfrac{1}{2}=b[/tex]
For an exponential function b cannot be negative. So, [tex]b=\dfrac{1}{2}[/tex].
Therefore, the value of a is 12000 and the value of b is [tex]\dfrac{1}{2}[/tex].

What is the value of x in:
3x + 2(x + 1) = 12?
A.12
B.6
C.10
D.2
Answer:
D
Step-by-step explanation:
3x + 2(x + 1) = 12 ← distribute and simplify left side
3x + 2x + 2 = 12
5x + 2 = 12 ( subtract 2 from both sides )
5x = 10 ( divide both sides by 5 )
x = 2 → D

Carol bought two chairs with triangular backs. For what value of x can you use
a triangle congruence theorem to show that the triangles are congruent?
Which triangle congruence theorem can you use? Explain.
Answer:
x = 4
Step-by-step explanation:
Two sides, GH and GI, in ∆GHI are of the same side length as corresponding two sides, TU and TV, in ∆TUV.
To prove that both triangles are congruent using the SSS Congruence Theorem, therefore, the their third sides, HI and UV must be equal.
Therefore,
9x - 21 = 15
Add 21 to both sides
9x - 21 + 21 = 15 + 21
9x = 36
Divide both sides by 9
x = 4

) Choose ALL the numbers that are less than 6.58. 6.583 6.5 6.58 5.98 6.538 6.49
Answer:
6.5, 6.49
Step-by-step explanation:
The numbers that are less than 6.58 is 6.58, 5.98, 6.538 and 6.49.
What is decimal?A group of numbers between integers on a number line are known as decimals. They are merely an additional mathematical representation of fractions.
Decimals allow us to express measurable quantities like length, weight, distance, money, etc. with greater accuracy. Integers, also known as whole numbers, are represented to the left of the decimal point, while decimal fractions are represented to the right of the decimal point. The next place, which is (1/10)th or tenth place value, is (1/10) times smaller if we move immediately from the first place.
Given number: 6.58
Now, we have to find the number less than 6.58
6.58 < 6.583
6.58 > 6.5
6.58 = 6.58
6.58 >5.98
6.58 > 6.538
6.58 > 6.49.
Hence, the numbers that are less than 6.58 is 6.58, 5.98, 6.538 and 6.49.

6th term 25,75,225,675,.... is it arithmetic or geometric. what's the explicit equation and the given term
Answer:
see explanation
Step-by-step explanation:
There is a common ratio r between consecutive terms, that is
[tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{75}{25}[/tex] = 3
[tex]\frac{a_{3} }{a_{2} }[/tex] = [tex]\frac{225}{75}[/tex] = 3
[tex]\frac{a_{4} }{a_{3} }[/tex] = [tex]\frac{675}{225}[/tex] = 3
This indicates the sequence is geometric with explicit formula
[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]
where a₁ is the first term and r the common ratio
Here a₁ = 25 and r = 3 , then
a₆ = 25 × [tex]3^{5}[/tex] = 25 × 243 = 6075
Flying lessons on weekdays cost m dollars per hour. Flying lessons on weekends cost 1.2m dollars per hour. The expression 9m+3(1.2m) represents the to
Answer:
The cost of lesson for 9 hours on weekdays and 3 hours on weekends
Step-by-step explanation:
Given
[tex]Weekdays = \$m /hour[/tex]
[tex]Weekends = \$1.2m/hour[/tex]
Required
What does 9m + 3(1.2m) represent
The expression can be split to:
9m and 3(1.2m)
For 9m:
From the question, we understand that:
[tex]m = 1\ hour[/tex]
Multiply both sides by 9
[tex]9 * m = 1\ hour * 9[/tex]
[tex]9 m = 9\ hours[/tex]
This means that:
9m = the cost of lessons for 9 hours on weekdays
For 3(1.2m):
From the question, we understand that:
[tex]1.2m = 1 \ hour[/tex]
Multiply both sides by 3
[tex]3 * 1.2m = 1 \ hour * 3[/tex]
[tex]3(1.2m) = 3 \ hours[/tex]
This means that:
3(1.2m) = the cost of lessons for 3 hours on weekends
Hence, the expression represents:
The cost of lesson for 9 hours on weekdays and 3 hours on weekends

Answer:
x = 2
Step-by-step explanation:
The 2 triangles are similar, thus the ratios of corresponding sides are equal, that is
[tex]\frac{x}{8}[/tex] = [tex]\frac{3.5}{14}[/tex] ( cross- multiply )
14x = 28 ( divide both sides by 14 )

A rectangle has a length of x and a with width 3 more than twice the length. A square has a side length of 3x. If both polygons have the same perimeter what is the value of x.
Answer:
x = 1
Step-by-step explanation:
Length of the rectangle = x
Width of the rectangle = 2x + 3
Side length of the square = 3x
Perimeter of the rectangle = 2(length + width)
= 2{x + (2x+3)}
= 2(x + 2x + 3)
= 2x + 4x + 6
= 6x + 6
Perimeter of a square = 4 * length
= 4 * 3x
= 12x
If both polygons have the same perimeter
Perimeter of the rectangle = Perimeter of a square
6x + 6 = 12x
6 = 12x - 6x
6 = 6x
x = 6/6
x = 1

I think it's D because the y-intercept is (0, -2), and in D the filled in circle is on (0, -2) and it goes up one and right one, which is the slope. Although C does this it ends with only one filled in circle, but D still has the two circles and line in between them.
