Help plz 13. Mildred is flying a kite on a 30 m string. The angle of elevation of the kite measures 40 degrees,
and Mildred's hand is 2 m above the ground. About how high is the kite off the ground?
a. 21.3 m
c. 19.3 m
b. 25 m
d. 23 m
Answer: 21.3m
Step-by-step explanation:
The height of the kite of the ground would be calculated as:
We have to calculate the question using a right angled triangle that has angle ACB as 90° while angle CAB will be 40°.
Therefore, the height of the kite would be:
= 30 sin 40 + 2
= 30 (0.6428 ) + 2
= 19.284 + 2
= 21.284 m
= 21.3 m
In the first 1/5 hour of a snowstorm 1/3 inches of snow fell in the snow continues at the same rate how much snow will fall in 4 1/5 hours
Answer:
70 (I think)
Step-by-step explanation:
1/3 is 3.33 (threes go on forever) but thats only for 1/5 of an hour, so you multiply 3.33 by 5 and get 16.66 (pretty sure the sixes also go on forever) and thats one full hour, so you multiply 16.66 by 4.20 (4 1/5 but in decimal form) and you get 70

The clothing store marked down all their shirts by 30%. If a shirt originally cost $24, what is the sale price of the shirt?
Answer:
$16.80
Step-by-step explanation:
Since the shirts are marked down by 30%, you need to multiply the cost of the shirt by the percentage.
$24 × 0.3 = $7.20
Next, subtract the discount from the original price to find the discounted price.
$24 - $7.20 = $16.80
Identify the set of numbers that makes up the domain in the relation ((-2,-2), (0, 2), (2, 4), (3, -6)).
0-2.0.2.3
0-2.0.3,4
0-6-2, 0.2.3.4
0-6-2, 2.4
Answer:
The first set, -2,0,2,3 are the domains of this relation.
Answer:
The correct answer is:
Option 1: -2,0,2,3
Step-by-step explanation:
When a relation is written in the form of ordered pairs.
In each ordered pair, the first element/coordinate is the input of the function and the second element//coordinate of ordered pair is the output.
The set of inputs is the domain of the relation.
Given relation is:
((-2,-2), (0, 2), (2, 4), (3, -6)).
The first element of each ordered pair is:
-2, 0, 2, 3
Hence,
The correct answer is:
Option 1: -2,0,2,3

At her birthday party, marcie's guests ate 2/3 of her birthday cake and her family ate 1/4 of the cake. How much cake was left after her party?
Answer:
1/12
Step-by-step explanation:
So you start with an equation. 2/3 plus 1/4= ?.
Step 1: Find a common donominator.
Count by each number until they meat up.
3 6 9 12
4 8 12
Step 2: Multiply.
Basically, make sure that if you do something to the bottom you do the same to the top. You have
[tex]\frac{2}{3}[/tex] = [tex]\frac{?}{12}[/tex]. 3 times 4 is 12. 2 times 4 is 8. Your new fraction is [tex]\frac{8}{12}[/tex].
[tex]\frac{1}{4}[/tex] = [tex]\frac{?}{12}[/tex]. 4 times 3 is 12. 1 times 3 is 3. Your new fraction is [tex]\frac{3}{12}[/tex].
Step 3: Just Add!
[tex]\frac{8}{12} + \frac{3}{12}= \frac{11}{12}[/tex]
Step 4: Answer the question! The question asks "How much cake is left. You know that a whole cake is [tex]\frac{12}{12}[/tex]. So, [tex]\frac{12}{12} -\frac{11}{12} = \frac{1}{12}[/tex]

What is exponential function?
" An exponential function is a mathematical function which can be expressed as y = [tex]a^{x}[/tex] where 'a' is any constant value not equals to 0 and 'x' is a variable which belongs to any real number."
According to the question,
y = 4²
If we compare with general form y = [tex]a^{x}[/tex] of exponential function we have,
a = 4
x = 2
Hence, we conclude that y = 4² is an exponential function.

2. 3rd row multiplied by the 3 columns : -4x² , 20x ,-24
Step-by-step explanation:
The table requires you to perform multiplication of the terms
The product is as follows;
1. 2nd row multiplied by the 3 columns
7x * x² = 7x³
7x * -5x = -35 x²
7x * 6 = 42
2. 3rd row multiplied by the 3 columns
-4 * x² = -4x²
-4 * -5x = 20x
