16) Find the lateral area of the regular pyramid. 5 cm www 24 cm
Answer:
LA = 624 cm²
Step-by-step explanation:
h² = 5² + 12²
h = 13
LA = 4 × bh/2
LA = 4 × (24 cm)(13 cm)/2
LA = (48 cm)(13 cm)
LA = 624 cm²
The graph of g(x)=|x-h|+k is shown on the coordinate grid.what must be true about the signs of h and k?
The correct option is the last one. h is negative and k is positive.
What can we say about h and k?
For the absolute value function:
g(x) = |x - h| + k
We know that the vertex is on the point (h, k).
On the graph, we can see that the vertex is on the point (-2, 1), then we have:
h = -2
k = 1
So the sign of h is negative and the sign of k is positive. The correct option is the last one.

The error is present in second step when cancelling numerator and denominator and the solution of the expression [tex](1+1/x)/(1-1/x^{2} )[/tex] is [tex]x/x-1[/tex].
Given Expression [tex](1+1/x)/(1-1/x^{2} )[/tex] and incorrect solution. and we need to identify the error and solve the expression correctly.
The expression is [tex](1+1/x)/(1-1/x^{2} )[/tex]
In the solution given the second step of cancelling 1's in numerator and denominator is wrong.
The solution which is correct is as under:
[tex](1+1/x)/(1-1/x^{2} )[/tex]
firstly take LCM in numerator and denominator
=[tex](x+1)/x/(x^{2} -1)/x^{2}[/tex]
Now we can write the expression properly.

The answer to this question is x/x₋1
Given the expression is 1₊1/x /1₋1/x²
Take the LCM of the denominators
we get, x₊1/x / x²₋1/x²
Now multiply the expression
=x₊1/x × x²/x²₋1
=(x₊1) x²/ x(x²₋1)
(x²₋1) is in the form of (a²₋b²)=(a₊b)(a₋b)
Therefore, (x₊1)x²/x(x₋1)(x₊1)
After cancelling like terms we get the answer as:
x/(x₋1)
Hence we get the simplification answer as x/(x₋1).

Let f(x)=1/x+x, where is a nonzero number.what is the product of all the values of a, such that f(a)=f(2a)?
The product of all the values of a, such that f(a)=f(2a) is -1/2
Functions and expressionsGiven the function below;
f(x)=1/x + x
f(a) = 1/a + a
f(2a) = 1/2a + 2a
If f(a) = f(2a), hence;
1/a + a = 1/2a + 2a
Collect the like terms

The minimum number of shirt they will sell to make the given profit is 192 shirts
Inequality expressionInequalities are equations not separated by an equal sign.
If a cheerleading team plans to sell t-shirts as a fundraiser and the teams goal is to make profit of at least $1248 with each t-shirt sold at $6.50, then the equation required is;
6.50t ≥ 1246

What is the inverse of f(x)= 1/3x + 2?
Answer:
y^-1 = 3x - 6
Step-by-step explanation:
f(x) = 1/3x + 2
The inverse function is where we swap out y for x and x for y. f(x) represents y, so we will be replacing it with x. Then, we solve and get a new equation for the inverse of y.
x = 1/3y + 2 (subtract 2 from both sides)
x - 2 = 1/3y (multiply by 3 on both sides)
y^-1 = 3x - 6

Substitute this into the second equation and solve for [tex]y[/tex].
[tex]2x + 4y = 12 \implies 2(7 - 3y) + 4y = 12 \\\\ \implies 14 - 6y + 4y = 12 \\\\ \implies -2y = -2 \\\\ \implies \boxed{y=1}[/tex]

[tex]2 (2x - y) + (3x + 2y) = 2\times3 + (-3) \implies 4x - 2y + 3x + 2y = 6 - 3 \\\\ \implies 7x = 3 \\\\ \implies \boxed{x = \dfrac37}[/tex]
Solve for [tex]y[/tex].
[tex]2x - y = 3 \implies 2\times\dfrac37 - y = 3 \\\\ \implies \dfrac67 - y = 3 \\\\ \implies -y = \dfrac{15}7 \\\\ \implies \boxed{y = -\dfrac{15}7}[/tex]

An amount of money 960gh was contributed by 80 students. If 714gh was contributed equally by 68 girls and the remaining amount was also contributed equally by boys. How much did each
i. Girl contribute
ii. Boy contribute
Each girl contributed 10.50gh
Each boy contributed 20.50gh
These are further explained and computed below:
The measure of central tendency being tested here is the mean, in other words, the resulting average when the total amount contributed by girls or boys is divided by the number of girls or boys.
The fact that 68 of the 80 students are girls means that the remaining 12 students are boys because 80 minus 68 gives 12.
each girl's contribution=total girls' contribution/number of girls
each girl's contribution=714/68
each girl's contribution=10.50gh
Total boys' contribution=total contribution-total girls' contribution
Total boys' contribution=960-714
Total boys' contribution=246
each boy's contribution=Total boys' contribution/number of boys
each boy's contribution=246/12
each boy's contribution=20.50gh

Each girl contributed 10.5gh and each boy contributed 20.5gh
How to determine the amount contributed?The given parameters are:
Total amount = 960gh
Number of students = 80
Amount contributed by girls = 714gh
Number of girls = 68
The amount contributed by each girl is:
Girl = Amount contributed by girls/Number of girls
This gives
Girl = 714gh/68
Evaluate
Girl = 10.5gh
The amount contributed by each boy is:
Boy = (Total - Amount contributed by girls)/(Total students - Number of girls)
This gives
Boy = (960gh - 714gh)/(80 -68)
Boy = 246gh/12
Evaluate
Boy = 20.5gh
Hence, each girl contributed 10.5gh and each boy contributed 20.5gh
