15. TRIANGLES Find the dimensions of a triangle if the base is 2/3 the measure of the height and the area is 12 square centimeters. (Lesson 4-3)
The dimensions of the triangle with a base that is 2/3 of its height and an area of 12 square centimeters are a base of 4 centimeters and the height of 6 centimeters.
Explanation:The question asks for the dimensions of a triangle. We are given that the base is 2/3 of the height and the area is 12 square centimeters. The formula for the area of a triangle is 1/2 * base * height. Since we know that the base is 2/3 of the height, we can denote the height as 'h' and the base as (2/3)h. From here, we can set up the equation 12 = 1/2 * (2/3)h * h, which simplifies to 12 = 1/3 * h². Solving for 'h', we find the height is √36 or 6 centimeters. Given the base is 2/3 of the height, the base, therefore, is 4 centimeters.

A highway makes an angle of 6 with the horizontal. This angle is maintained for a horizontal distance of 5 miles.
To the nearest hundredth of a mile, how high does the highway rise in this 5-mile section? Show the steps you use to find the distance.
Within a specific stretch spanning 5 miles, the roadway inclines approximately 0.53 miles or 2771.64 feet, rounded to the nearest hundredth of a mile.
Trigonometric principles aid in determining the elevation gained by the highway over this distance.
Given:
An angle of ascent (θ) of 6 degrees and a horizontal distance (adjacent side) of 5 miles, our objective is to ascertain the vertical distance (opposite side).
Utilizing the tangent function in trigonometry:
[tex]\[ \tan(\theta) = \frac{{\text{{opposite}}}}{{\text{{adjacent}}}} \][/tex]
[tex]\[ \tan(6^\circ) = \frac{{\text{{height}}}}{{5}} \][/tex]
The calculation for the height is:
height = 5 × tan(6°)
Plugging in the values:
height ≈ 5 × 0.1051
height ≈ 0.5255 miles
To convert this to feet (1 mile = 5280 feet):
height ≈ 0.5255 × 5280
height ≈ 2771.64 feet
Thus, within this 5-mile segment, the roadway ascends approximately 0.53 miles or 2771.64 feet, rounded to the nearest hundredth of a mile.
For f(x) = 2x + 1 and g(x) = x2 – 7, find (f – g)(x).
A. –x2 + 2x – 6
B. 2x2 – 15
C. x2 – 2x – 8
D. –x2 + 2x + 8
HELP!! give me the correct answer
For the function, f(x) = 2x + 1 and g(x) = x² – 7, (f – g)(x) will be D. –x² + 2x + 8
How to calculate the functionTo find (f - g)(x), we need to subtract the function g(x) from the function f(x).
f(x) = 2x + 1
g(x) = x² - 7
(f - g)(x) = f(x) - g(x)
Substituting the given functions:
(f - g)(x) = (2x + 1) - (x² - 7)
Now let's simplify:
(f - g)(x) = 2x + 1 - x² + 7
Combining like terms, we have:
(f - g)(x) = -x² + 2x + 8
Therefore, the answer is D. -x² + 2x + 8.

Erica bought 3 1/2 yards of fabric. If she uses 2/3 of the fabric to make a curtain, how much will she have left?
Final answer:
Erica will have 1 1/6 yards of fabric left after using 2/3 of the 3 1/2 yards she purchased to make a curtain.
Explanation:
The student's question is about how much fabric Erica will have left after using 2/3 of the 3 1/2 yards she bought to make a curtain. To solve this problem, we first need to convert the mixed number of yards of fabric to an improper fraction. We start by multiplying the whole number, 3, by the denominator of the fraction, 2, and then adding the numerator, 1. This gives us (3 × 2) + 1 equals 7, so Erica has 7/2 yards of fabric.
Next, we determine how much fabric she uses by multiplying 7/2 yards by 2/3. Doing the multiplication, (7/2) × (2/3), we can cancel out the common factor of 2 to simplify the calculation. The result is 7/3 yards of fabric used for the curtain.
To find out how much fabric is left, we subtract the used fabric from the total amount Erica originally had, which is 7/2 yards. So, we calculate 7/2 - 7/3 yards. To subtract these fractions, they need to have a common denominator. Multiplying 7/2 by 3/3 and 7/3 by 2/2 gives us equivalent fractions with a common denominator of 6. We now have (21/6) - (14/6) yards, and subtracting these gives us 7/6 yards of fabric remaining. This can also be represented as 1 1/6 yards, which is how much Erica will have left after making the curtain.

Straight-line depreciation is a method of calculating an asset’s value by subtracting its salvage value from its acquisition or purchase price divided by the estimated useful life of the asset. suppose a manufacturing robot cost $1.5 million in 2005 and is sold in 2010 for $50,000. what is the linear equation representing the value of the robot?
Answer:
Linear equation is V(t) = 1500 - 290t
Step-by-step explanation:
To find the linear equation representing the value of the robot we will calculate per year depreciation in the cost of the robot.
Rate of depreciation = [tex]\frac{\text{(Manufacturing cost in 2005-selling price in 2010)}}{5}[/tex]
= [tex]\frac{[(1.5)(10^{6})-50000]}{5}[/tex]
= [tex]\frac{(1500000-50000)}{5}[/tex]
= [tex]\frac{1450000}{5}=290000[/tex]
If depreciation is represented by V(t) (in $000) then equation will be
V(t) = 1500 - 290t

How large is the sample?
a.200 cartons
b.the 50th carton
c.1000 cartons
d.cannot determine from this information
Answer:
Option a is correct
200 cartons is the sample size
Step-by-step explanation:
As per the statement:
For ten shipments of 1000 cartons of eggs, she examines every 50th carton to see how many cartons contain cracked eggs.
First examine how many cartons are examined per shipment.
For every 50th cartons, 1 are examined
For every 100th cartons, 2 are examined
then;
For 1000 cartons , we have 20 are examined.
Examined per shipment = 20 cartons
We have to find how large is the sample.
Since, there are total 10 shipment
then;
For 10 shipment, we have
[tex]20 \times 10 = 200[/tex] cartons
Therefore, 200 cartons is the sample size

Missing number to complete the factorization is 3.
What is factorization?Factorization can be defined as the process of breaking down a number into smaller numbers which when multiplied together arrive at the original number. These numbers are broken down into factors or divisors.
Given expression
[tex]x^{3}+x^{2} -21x-45=(x+3) (x-5) (x+a)[/tex]
