Answer:
AB = 15
m∠A = 53.1°
m∠B = 36.9°
Step-by-step explanation:
From the picture attached,
By Applying Pythagoras theorem,
AB² = AC² + BC²
AB² = 9² + (12)²
AB² = 81 + 144
AB = √225
AB = 15
tan(B) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
= [tex]\frac{12}{9}[/tex]
= 1.3333
B = [tex]\text{tan}^{-1}(1.3333)[/tex]
= 53.13
≈ 53.1°
Since, m∠A + m∠B + m∠C = 180°
m∠A + 53.1° + 90° = 180°
m∠A = 180°- 143.1°
= 36.9°
Answer:
AB = 15
m∠A = 53.1°
m∠B = 36.9°

(Stop doing the math the instant you can tell which number is larger.)
.............................
Answer:
Quick Market is the better buy.
...........................
To solve this in your head:
1) You can see that "6 apples for (about) $1.20" is about 20 cents each.
2) For the other apples to be 20 cents each, the price for 8 would have to be about $1.60
3) Because the cost of 8 apples is less than $1.60, then the Quick Market apples are cheaper than the other ones.
The Quick Market will be the place for better buy than Stop and Save.
Comparison of rates for better buy: Find the rate of one unit. Compare the rates to decide the better buy.Given in the question,
Total amount paid for 8 apples at The Quick Market = $1.45 Total amount paid for 6 apples at Stop and Save = $1.22Rate of apples at The Quick Market = [tex]\frac{\text{Total amount paid}}{\text{Number of apples}}[/tex]
= [tex]\frac{1.45}{8}[/tex]
= $0.18125
≈ $0.18 per apple
Rate of apples at Stop and Save = [tex]\frac{1.22}{6}[/tex]
= $0.20333
≈ $0.20 per apple
Since, $0.18 is less than $0.22, The Quick Market will be the place for better buy than Stop and Save.

Step-by-step explanation:
Convert everything to decimals for ease of comparison.
0.075 ⇒ Leave as is.
75% ⇒ Divide by 100 to make it a decimal number.
= [tex]\frac{75}{100}[/tex]
= 0.75
3/4 ⇒ Divide the numerator by the denominator.
= 0.75
Put them in order of place value:

Add 2.8x to both sides.

Subtract 0.8 from both sides.
-0.4x < -2.8
Divide both sides by -0.4. Remember that when you multiply or divide both sides of an inequality by a negative number, the inequality symbol changes direction.

What is function?In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.
Given:
f(x)=1/2x-3
Now, subtract 6 from the input of f to create a new function g
g(x)= 1/2x-3 -6
g(x)= 1/2x -9
and, multiply the input of function g by 4
h(x)= 4( 1/2x -9)
h(x) = 2x- 36
Hence, the value of h(x)= 2x- 36.

Pls can someone help me factorise: 4u²‐u-3
Answers
Answer:
(u - 1)(4u + 3)
Step-by-step explanation:
Given
4u² - u - 3
Consider the factors of the product of the coefficient of the u² term and the constant term which sum to give the coefficient of the u- term.
product = 4 × - 3 = - 12 and sum = - 1
The factors are - 4 and + 3
Use these factors to split the u- term
4u² - 4u + 3u - 3 ( factor the first/second and third/fourth terms )
= 4u(u - 1) + 3(u - 1) ← factor out (u - 1) from each term
= (u - 1)(4u + 3)
Thus
4u² - u - 3 = (u - 1)(4u + 3) ← in factored form
