A kite has a string tired to its center. The kite is let out on 90ft of the string and the other end of the string is held at 4ft above the ground. From where the string is held, the angle of elevation to the center of the kite is 40°. If you maintain the same angle of elevation from where the string is held, how much more string would you need to let out for the kite to fly 10ft higher? Round to the nearest tenth of a foot.
Length of more string needed to fly the kite 10 feet higher is 15.55 ft.
What is angle of elevation?The angle of elevation is the angle between the horizon and the line of sight. If the line of sight is above the horizon, the angle formed is the elevation angle.
Given,
Height of the string above the ground = 4 feet
Angle of elevation = 40°
length of the string = 90 ft
sin 40° = x/90
0.643 = (x)/90
x = 57.87 ft
For 10 ft higher, let the length be 90 + y
sin 40° = (57.87 + 10)/(90 + y)
0.643 = (57.87 + 10)/(90 + y)
57.87 + 0.643y = 57.87 + 10
0.643y = 10
y = 10/0.643
y = 15.55 ft
Hence, 15.55ft more string is needed to let out kite to fly 10 ft higher.

Final answer:
To find the extra string needed to raise the kite by 10ft, we can use trigonometry and set up an equation based on the sine function. By plugging in the values and solving the equation, we find that you would need 37.7ft of extra string.
Explanation:
To find how much more string you would need to let out for the kite to fly 10ft higher, we can use trigonometry. First, let's find the height of the kite above the ground when 90ft of string is let out. We can use the sine function: sin(40°) = height / 90ft. Rearranging the equation, we find height = sin(40°) * 90ft = 57.7ft. Now, to find the extra string needed to raise the kite by 10ft, we can set up a similar equation: sin(40°) = (height + 10ft) / (90ft + x), where x is the extra string. Rearranging the equation, we get x = ((height + 10ft) / sin(40°)) - 90ft. Plugging in the values, we have x = ((57.7ft + 10ft) / sin(40°)) - 90ft = 37.7ft.

Step-by-step explanation:
Final answer:
The greatest common factor of the expressions [tex]16m^6n^4[/tex], [tex]4m^3n^5[/tex], and [tex]2m^5n^3[/tex] is [tex]2m^3n^3[/tex].
Explanation:
The question is asking for the greatest common factor (GCF) of the three algebraic expressions provided: [tex]16m^6n^4[/tex], [tex]4m^3n^5[/tex], and [tex]2m^5n^3[/tex]. To find the GCF, we need to determine the highest powers of m and n that divide evenly into all three expressions.
For the variable m, the smallest exponent is 3 (in the term [tex]4m^3n^5[/tex]). For the variable n, the smallest exponent is 3 (in the term [tex]2m^5n^3[/tex]). Therefore, the GCF is [tex]2m^3n^3[/tex].
We also look at the numerical coefficients (16, 4, and 2) and find their GCF to be 2.

The parent function f(x) = x3 is translated to form g(x), as shown on the graph. The translated function can be written in the form
g(x) = (x – h)3 + k.
Answer: First option
Step-by-step explanation:
By definition, the horizontal shift depends on the value of h and the vertical shift depends on the value of k.
[tex]f(x)=(x-h)^3[/tex] indicates that the function if shifted to the right h units.
[tex]f(x)=(x+h)^3[/tex] indicates that the function if shifted to the left h units.
[tex]f(x)=f(x)-k[/tex] indicates that the function if shifted down k units.
[tex]f(x)=f(x)+k[/tex] indicates that the function if shifted up k units.
Then:
If h is positive, the graph will shift to the right.
If k is negative, the graph will shift down.
As you can see in the graph, the function is shifted 4 units to the right and 2 units down. Therefore g(x) has the form:
[tex]g(x)=(x-4)^3-2[/tex]

Based on the trend in the approximately how many free throws would a player be expected to make if he attempted 60 free throws
To gauge how many free throws a player would make out of 60 attempts, we need to know the player's free throw success rate. Assuming similar conditions to the example given where Carlos, the soccer player has a success rate of 65%, the basketball player would make approximately 39 successful free throws from 60 attempts.
Explanation:
The question seems to be asking how many free throws a player would be expected to make if he attempted 60 free throws. The missing information here would be the player's free throw success rate which isn't provided. However, let's use the example of Carlos from college soccer as an analogy; if Carlos has a success rate of 65%, then for every 100 attempts, he would make 65 goals. Now if the basketball player followed the same trend and had a success rate of 65%, and he attempted 60 free throws, we would calculate 65% of 60. This equals 39, therefore we would be expecting the player to make approximately 39 free throws.

What is the length of the hypotenuse of right DEF shown
Answer:
50.45
Step-by-step explanation:
Pythagoras theorem
32^2 + 39^2 =x^2
1024+ 1521 =x^2
2545=x^2
[tex]\sqrt{2545} =x[/tex]
x= 50.45
The length of x is 50.44
Step-by-step explanation:According to Pythagorean theorem
Hyp² = Base² + Perp²Putting the values
Hyp² = 39² + 32²
Hyp² = 1521 + 1024
Hyp² = 2545
Taking square root on both sides we get
Hyp = 50.44
Suppose a wild fire is doubling in size every 6 hours. If the initial size of the fire was 1 acre, how many acres will the fire cover in 2 days?
Step-by-step explanation:
2 days= 24 hours in 1 day, so multiply that by 2 to get 48 hours total.
Now find the amount of time the wild fire doubles by dividing 48 total hours by 6. So it will double 8 times
The size was 1 acre. Let's multiply by 2, 8 times
1
2
4
8
16
32
64
128
The fire will cover 128 acres in two days.
The wildfire, which is doubling every 6 hours, would cover 256 acres of land over a two day period.
Explanation:The problem involves exponential growth, which is a concept in mathematics where a quantity increases exponentially over time. According to the problem, the size of the fire is doubling every 6 hours. So, we have 24 hours in a day, and two days would give us 48 hours.
Now, divide the total hours (48) by the hours it takes for the fire to double in size (6), we get 8. This is the number of times the fire doubles in size over a 2 day period.
Since the fire was initially 1 acre, after 8 doubles or in 2 days, it would cover 28 or 256 acres of land.

For St. Patrick's day, Mrs. G's sixth grade class was given a choice of four different drinks. One quarter of the class chose green milkshakes, one third of the class chose green ginger ale, one eighth of the class chose the green milk and one sixth of the class chose green juice. How many students did not have a drink?
Answer:
1/8 of the number of students
Step-by-step explanation:
1/4 + 1/3 + 1/8 + 1/6 =
= 6/24 + 8/24 + 3/24 + 4/24
= 21/24
= 7/8
7/8 of the class chose drinks.
1 - 7/8 = 8/8 - 7/8 = 1/8
That means that 1/8 did not have a drink.
Since we don't know the number of students in her class, we cannot tell the number of students who did not have a drink, but we do know it is 1/8 of the number of students.

What is the difference between 8x3 – 2x2 + 5x – 7
and 5x3 – 3x2 – 2x + 4?
Answer:
First polynomial minus the second polynomial:
3 x³ + x² + 7 x - 11.
Step-by-step explanation:
The question asks for the difference between the two cubic polynomials (maximum power of x is three.) As the other answerer mentioned, the question doesn't say anything about the value of x. In that case, the difference between the two polynomials will still be a polynomial about x.
The power x in the difference can be as high as three. Assume that to be a cubic polynomial.
? x³ + ? x² + ? x + ?.
What are the values of each coefficient?
For example, the coefficient in front of x³ in the difference is the difference between the coefficients of x³ in the two original polynomials.
The coefficient of x³ in the first polynomial 8 x³ - 2 x² + 5 x - 7 is 8.The coefficient of x³ in the second polynomial 5 x³ - 3 x² - 2 x + 4 is 5.Subtract the second coefficient from the first. 8 - 5 = 3. In other words, 3 is the value of the x³ coefficient in the difference.
3 x³ + ? x² + ? x + ?.
Repeat this step for the x² and x coefficients.
x²: -2 - (-3) = -2 + 3 = 1.x: 5 - (-2) = 5 + 2 = 7.3 x³ + x² + 7x + ?.
The constant in the difference is the difference between the two constants.
-7 - 4 = -11.
Hence the difference:
3 x³ + x² + 7x - 11.
Alternatively, group the terms by the power of x:
(8 x³ - 2 x² + 5 x - 7) - (5 x³ - 3 x² - 2 x + 4)
= (8 x³ - 5 x³) + (-2 x² + 3 x²) + (5 x + 2 x) + (-7 - 4)
= 3 x³ + x² + 7 x - 11.
Find k so that the equation 9x^2 +12x+k =0 has one real number (double) root.
For one real (double) root, set discriminant [tex]\( \Delta \)[/tex] to zero: [tex]\( 144 - 36k = 0 \)[/tex]. Solve to get [tex]\( k = 4 \)[/tex].
To find the value of [tex]\( k \)[/tex] so that the equation [tex]\( 9x^2 + 12x + k = 0 \)[/tex] has one real number (double) root, we use the discriminant [tex](\( \Delta \))[/tex] of the quadratic equation. For a double root, [tex]\( \Delta = 0 \)[/tex].
The discriminant is given by [tex]\( \Delta = b^2 - 4ac \)[/tex], where [tex]\( a = 9 \)[/tex], [tex]\( b = 12 \)[/tex], and [tex]\( c = k \)[/tex].
Substitute these values into the discriminant formula:
[tex]\[ \Delta = (12)^2 - 4(9)(k) \][/tex]
[tex]\[ = 144 - 36k \][/tex]
For a double root, [tex]\( \Delta = 0 \)[/tex], so:
[tex]\[ 144 - 36k = 0 \][/tex]
[tex]\[ 36k = 144 \][/tex]
[tex]\[ k = \frac{144}{36} \][/tex]
[tex]\[ k = 4 \][/tex]
Therefore, [tex]\( k = 4 \)[/tex] to have one real number (double) root.
15 feet to 33 ft percent of change
Answer:
120%
Step-by-step explanation:
See how much % of 15 and increase to 33 is.
33 - 15 = 18, so there is a change of 18 feet.
18/15 = 1.2
1.2 is 120% as a percent. So there is a 120% change from 15 to 33
Final answer:
The percent of change from 15 feet to 33 feet is found by dividing the difference between the values by the original value and then multiplying by 100, which results in a 120% change.
Explanation:
To calculate the percent of change from 15 feet to 33 feet, first, find the difference between the two values. The difference is 33 feet - 15 feet = 18 feet. Then, divide this difference by the original value (15 feet) and multiply the result by 100 to get the percentage. Thus, the percent of change is (18 feet / 15 feet) × 100 = 120%.

{decreased|TA}
In short, any high or low value outlier affect the data set the same way. When the outlier is removed, the standard deviation decreases.
Given that, a set of data has a high-value outliner.
What is an outliner?In simple terms, an outlier is an extremely high or extremely low data point relative to the nearest data point and the rest of the neighboring co-existing values in a data graph or dataset you're working with. Outliers are extreme values that stand out greatly from the overall pattern of values in a dataset or graph.
When you have an outlier that is higher then the bulk of the data, the standard deviation is larger then it would be without the outlier. If the outlier was lower than the bulk of data, then the standard deviation would again be larger then it would be without the outlier and the mean would go down when the outlier is removed. Where it differs is the fact that removing the outlier would result in an increase of the mean instead of a decrease.
Therefore, in short, any high or low value outlier affect the data set the same way. When the outlier is removed, the standard deviation decreases.
