Answer:
One of the altitude formed from the vertex to the base and its magnitude given as 12cm
There is also a hypotenuse whose length is 15cm
By pythagorean theorem b^2 +a^2= c^2
so 12^2+a^2 = 15^2
=> 144+a^2 = 225
=> a^2 = 225-144
=> a^2 = 81
so the length of a = √81 = 9 cm (ans)

= 15 + 2(5)
= 15 + 10

What are the characteristics of the graph of the inequality x ≥ -2? The ray will move to the left. The ray will move to the right. It will use an open circle. It will use a closed circle.(multiple answers)
Answers
Answer:
Step-by-step explanation:
The inequality x ≥ -2 is graphed on a number line. -2 is the smallest possible value. All subsequent values are larger and therefore lie to the right of -2.
Thus, the following are true:
1. The ray will move to the right (because x begins at -2 and increases, which means moving to the right on the number line).
2. It will use a closed circle (because x = -2 is part of the solution set).
Answer: The ray will move to the right and it will be a closed circle.

2) Find the remainder when x3 + x2 - 20 is divided by
(x + 2) by using remainder theorem.
{ANS: R = -24}
Answers
Answer:
Remainder = –24
Step-by-step explanation:
x³ + x² – 20 divide by x + 2
We can obtain the remainder when
x³ + x² – 20 is divided by x + 2 using the remainder theorem as follow:
We'll begin by calculating the value of x from x + 2. This is illustrated below:
x + 2 = 0
Collect like terms
x = 0 – 2
x = –2
Finally, we shall determine the remainder by substituting –2 for x in
x³ + x² – 20. This is illustrated below:
x³ + x² – 20
x = –2
Remainder = (–2)³ + (–2)² – 20
Remainder = –8 + 4 – 20
Remainder = –24
Therefore, the ramainder when
x³ + x² – 20 is divided by x + 2 is –24

What are the x-intercepts of the equation y=4x^2-16
Answers
Answer:
x = ± 2
Step-by-step explanation:
To find the x- intercepts let y = 0 , that is
4x² - 16 = 0 (add 16 to both sides )
4x² = 16 ( divide both sides by 4 )
x² = 4 ( take the square root of both sides )
x = ± [tex]\sqrt{4}[/tex] = ± 2
The x- intercepts are x = - 2 and x = 2

Which interval or union of intervals represents the values for which f(x) is ≤ 0? Select the correct choice below and fill in the answer boxes to complete your choice.
Answers
Answer:
(-∞, -1]∪{5}
Step-by-step explanation:
We know that:
f(x) ≤ 0 is true if the graph of the function is intersecting the x-axis or below the x-axis.
So we can just look at the graph, we can see that in the interval:
(-∞, -1] (the value x = -1 is included, that is why we use the symbol ] instead of the parenthesis)
the graph is below or intersecting the x-axis
and this also happens at x = 5 or just denoted as {5}
Then the correct notation is:
(-∞, -1]∪{5}

1. I estimate that the error in measuring the area of the lot is about 10% so we write the area as 400 sq ft +- 10%, which means that the lot can be as small as 360 sq ft or as large as 440 sq ft. We tack on 15% more on the number of pieces of sod to account of the plot's irregularities. Since each piece of sod is 2 sq ft, the number of pieces we must get is 440/2 = 220 pieces +- 15% or 253 pieces
2. The nominal value is jus the average weight which is 59.5 g. The tolerance is (3.5g/59.5g)×100% = 5.88% and the measurement range is from 56g to 63g.
Pat bought 6 shirts that were all the same price. He used a traveler's
check for $25, and then paid the difference of $86. What was the
price of each shirt?
Answers
Answer:
Each shirt costs $18.50
Step-by-step explanation:
Questions such as these usually involve quite simple calculations, but they are important in being able to convert a scenario described in words into math calculations.
First, read the information carefully and then summarize what you are given in short sentences. Pat bought 6 shirts. He paid using a check and cash.
The total amount paid was $ 25 + $ 86 = $ 111
The shirts all cost the same price.
The cost of each shirt was: 111 ÷ 6 = $ 18.50
Answer:
Each shirt was 18.50
Step-by-step explanation:
The total cost of the 6 shirts was 25+86 = 111
Divide the total by 6 to find the cost of each shirt
111/6 =18.5
Each shirt was 18.50

Step-by-step explanation:
Here, we want to get the amount shared
Let us call the amount x
Total ratio is 5 + 4 = 9
Kwame had GHC 9
Thus;
5/9 * x = 9
5 * x = 9 * 9
5x = 81
x = 81/5
x = GHC 16.2
