By checking the definitions of typical functions, we conclude that the function f(x) = 3 · 1.5ˣ is an exponential growth function. (Correct answer: D)
How to determine the nature of the function
In this question we must determine the kind of function according to its characteristics based on definitions of typical functions, which are represented below:
Quadratic
y = a · x² + b · x + c
This function is reduced into a linear function when a = 0.
Exponential
[tex]y = a \cdot b^{c\cdot t}[/tex]
Where:
c > 0 - Exponential growth.c < 0 - Exponential decay.By checking the definitions of typical functions, we conclude that the function f(x) = 3 · 1.5ˣ is an exponential growth function. (Correct answer: D)
Remark
The statement is poorly formatted. The correct statement is presented below:
Identify the type of function represented by f(x) = 3 · 1.5ˣ:
A. Quadratic
B. Exponential decay
C. Linear
D. Exponential growth

[tex]14x - 196 = 0[/tex]
thankyou! :)
Answer:
x = 14
Step-by-step explanation:
14x - 196 = 0
14x = 0 + 196
14x = 196
x = 196 ÷ 14
x = 14
[tex]14x - 196 = 0 \\ \\ \implies14x = 0 + 196 \\ \\ \implies 14x = 196 \\ \\ \implies \: x = \frac{196}{14} \\ \\ \implies \: x = 14[/tex]

find the value of y
Answer:
[tex]\boxed{\sf{y=-11}}[/tex]Step-by-step explanation:
GIVEN:
To find the value of y, isolate it on one side of the equation.
2y-6-3y+5
Solutions:
First, add by 6 from both sides.
2y-6+6=3y+5+6
Solve.
Add the numbers from left to right.
5+6=11
2y=3y+11
Then, you subtract by 3y from both sides.
2y-3y=3y+11-3y
Solve.
-y=11
Divide by -1 from both sides.
-y/-1=11/-1
Solve.
Divide these numbers goes from left to right.
11/-1=-11
[tex]\Longrightarrow: \boxed{\sf{y=-11}}[/tex]
Therefore, the final answer is y=-11.I hope this helps. Let me know if you have any questions.

Answer:
144 ft³
Step-by-step explanation:
This "irregular shape" is a composite shape that can be considered to be any of these compositions:
extending the middle horizontal surface cuts the shape into two blocks: upper left: 2 ft high, 3 ft wide, 6 ft deep; and lower: 2 ft high, 9 ft wide, and 6 ft deep.extending the middle vertical surface cuts the shape into two blocks: left: 4 ft high, 3 ft wide, and 6 ft deep; and right: 2 ft high, 6 ft wide, and 6 ft deep.A larger block with a smaller block cut out of the upper left: larger block: 4 ft high, 9 ft wide, and 6 ft deep; cutout: 2 ft high, 6 ft wide, and 6 ft deep.The volume of any one of these blocks is the product of height, width, and depth. The above decompositions are evaluated here.
1.V = HWD
V = (2 ft)(3 ft)(6 ft) +(2 ft)(9 ft)(6 ft) = 36 ft³ + 108 ft³ = 144 ft³
__
2.V = (4 ft)(3 ft)(6 ft) +(2 ft)(6 ft)(6 ft) = 72 ft³ +72 ft³ = 144 ft³
__
3.V = (4 ft)(9 ft)(6 ft) -(2 ft)(6 ft)(6 ft) = 216 ft³ -72 ft³ = 144 ft³
Travis must use 144 ft³ of concrete to make the block.
Given the regular polygon, what is the measure of each numbered angle?
Answer:
Answer A
Step-by-step explanation:
Approach 1
B, C, and D are wrong because angles 1 and 2 are congruent.
Therefore your answer of both being 60°
Approach 2
Let x = angle 1.
360/x = 6
x = 60°.
Therefore Angle 1 is 60°
An interior angle of a hexagon is 120°
Let y = angle 2.
y is half of 120°
So 120/y = 2
y = 60°

Order the numbers from least to greatest. 0.3, 9/25, 33%, 0.35
Answer:
0.3(least)
0.33
0.35
0.36(greatest)
Step-by-step explanation:
Okay, so first we need to have all of our numbers in the same category of variable. So first, we will convert 9/25 to a decimal.
To do that, we must divide 9 by 25 to get our answer of 0.36.
Now, we will convert the 33% to a decimal by dividing it by 100 to get 0.33
We now have our list, which should be ordered as:
0.3
0.33
0.35
0.36

What is the lateral surface area of this right pyramid with a square base?
Answer:
The lateral surface area of a square pyramid is the sum of the areas of the side faces only, whereas the surface area is the lateral area + area of the base. The lateral area of a square pyramid = 2al (or) 2a√[(a 2 /4) + h 2]. To get the surface area, we need to add the area of the base (which is a 2) to each of these formulas.The surface area of a square pyramid = a 2 + 2al (or) a 2 + 2a[(a 2 /4) + h 2]. where, a = Length of the base (square) l = slant height; h = height of the pyramid.

For an amount of 6250 Peso, Hank have the quantities of the following denominations: 2503 bills of 50 peso, 2498 bills of 200 peso and 1249 bills of 500 peso.
How to apply systems of linear equations in real life equations
In this question we must translate the statement of the problem into mathematical expressions and then we must solve the resulting system. We need three equations that describe the quantities of 50 peso, 200 peso and 500 peso bills:
y = x - 5 (1)
0.5 · y = z (2)
x + y + z = 6250 (3)
The solution of the system of linear equations is described below:
x = 2503, y = 2498, z = 1249

Combine the terms through trigonometric identity and simplify, this should be your answer(not the actual result of the problem, just the simplified expression).
Answer:
Step-by-step explanation:
The rule is generally to reduce anything that isn't a sin(theta) or cos(theta) down to those two.
Givens
Tan(a) = sin(a) / cos(a)
sin(2a) = 2 sin(a)*cos(a)
Solution
Tan(a)/Sin(2a) = sin(a) / cos(a) // 2 sin(a) * cos(a) / 1 Invert and multiply
Tan(a)/Sin(2a) = sin(a) / cos(a) * 2 sin(a) * cos(a) Cancel and combine

9. Arianna has two piles of newspapers
to take to recycling. The first pile
weighs 10 pounds 7 ounces. The
second pile weighs 148 ounces. What
is the total weight of the newspapers?
A. 19 pounds 11 ounces
B. 22 pounds 11 ounces
C. 25 pounds 3 ounces
D. 29 pounds 3 ounces
Answer:
(D) 29 pounds 3 ounces
Step-by-step explanation:
1 pound = 16 ounces
Therefore 10 pounds = 16 * 10 = 160 ounces
160 + 7 = 167 ounces (first pile)
Total Weight of Newspapers = Weight of First Pile + Weight of Second Pile
= 167 + 148 = 315 ounces
As 16 ounces = 1 pound
1 ounce = 1/16 pound
315 ounces = (1/16) * 315 = 19.6875 pounds
1 pound = 16 ounces
0.6875 pounds = 16 * 0.6875 = 11
19 + 11 = 30 pounds, which is close to ans (D)
