Answer:
32 posts
Step-by-step explanation:
In terms of fence-post spaces, the corral is 10 by 6, so its perimeter is ...
P = 2(10 +6) = 32 . . . . . fence post spaces.
Patrick intends to paint 32 fence posts.
Final answer:
Patrick needs to paint a total of 32 fence posts around the rectangular corral. This total counts the posts for both pairs of sides after considering that the four corner posts have been counted twice.
Explanation:
The question involves calculating the total number of fence posts needed to surround a rectangular corral. Since the corral is 50 ft by 30 ft, and fence posts are spaced 5 feet apart, we must calculate how many posts are needed on each side of the rectangle and then add them together.
To begin with, for each of the longer sides (50 ft), we would need 50 ft ÷ 5 ft/post = 10 posts per side. However, we need to add one more post to close the rectangle, so we have 10 + 1 = 11 posts on each of the longer sides. For the shorter sides (30 ft), it would be 30 ft ÷ 5 ft/post = 6 posts per side, plus the extra post to close the rectangle, resulting in 6 + 1 = 7 posts on each of the shorter sides.
To get the total number of posts, we add up the posts on all sides: (11 posts × 2) + (7 posts × 2) = 22 + 14 = 36 posts. However, we must consider that we have counted the corner posts twice, once for each side they join. Since there are four corners, we subtract four posts from our total, resulting in 36 - 4 = 32 posts that Patrick needs to paint.
It takes Ebru 13 minutes to bike to school. If she walks, it takes her twice as long. Ebru leaves for school at 7;15 What time will Ebru get to school if she walks?
Answer:
[tex]7;41[/tex]
Step-by-step explanation:
Let
x----> the time it take Ebru to walk to the school
we know that
[tex]x=2(13)=26\ min[/tex]
so
[tex]7;15 +26\ min=7;41[/tex]
Ebru takes 26 minutes to walk to school, twice as long as biking. Leaving at 7:15 AM means she would arrive at school by walking at 7:41 AM.
If Ebru bikes to school, it takes her 13 minutes. Walking takes her twice as long, which would be 26 minutes. If Ebru leaves her house at 7:15 AM, we can calculate the time she will get to school by walking by adding 26 minutes to the departure time.
7:15 AM + 20 minutes = 7:35 AM7:35 AM + 6 minutes = 7:41 AMTherefore, if Ebru walks to school, she will arrive at 7:41 AM.
The dimensions of Square A are three times The dimensions of Square B. The area of Square A is 1,296 cm2. What is the area of Square b?
Square B Area = 144cm²
Square B = X
The dimensions of Square A are three times The dimensions of Square B
Square A = 3 * Square B
Square A = 3X
The area of Square A is 1,296 cm2.
Square A Area = (3X)² = 1296
Square B Area = X²
Solve to find X.
(3X)² = 1296
3X = 36
X = 36/3 = 12
Square B Area = 12² = 144
Square B Area = 144cm²
Final answer:
The area of Square B is 144 cm², calculated by dividing the area of Square A (1,296 cm²) by 9, because the area of a square scales with the square of its linear dimensions.
Explanation:
The area of Square A is given as 1,296 cm². Since the dimensions of Square A are three times the dimensions of Square B, we can find the area of Square B by understanding that area scales in proportion to the square of the linear dimensions. This means that if one dimension is three times another, the area will be nine times (3² = 9) larger.
To find the area of Square B, we simply divide the area of Square A by 9:
Area of Square B = Area of Square A / 9
Area of Square B = 1,296 cm² / 9
Area of Square B = 144 cm².
Therefore, the area of Square B is 144 cm².
Find the absolute maximum and absolute minimum values of f on the given interval. f(x) = ln(x2 + 2x + 4), [−2, 2] Step 1 The absolute maximum and absolute minimum values of the function f occur either at a critical number or at an endpoint of the interval. Recall that a critical number is a value of x where f '(x) = 0 or where f '(x) doesn't exist. We begin by finding the critical numbers. f '(x) =
[tex]f(x)=\ln(x^2+2x+4)\implies f'(x)=\dfrac{2x+2}{x^2+2x+4}[/tex]
The numerator determines where the derivative vanishes (the denominator has a minimum value of 3, since [tex]x^2+2x+4=(x+1)^2+3\ge3[/tex]).
[tex]2x+2=0\implies x=-1[/tex]
At this critical point, we have
[tex]f(-1)=\ln((-1)^2+2(-1)+4)=\ln3\approx1.099[/tex]
At the endpoints, we have
[tex]f(-2)=\ln4\approx1.386[/tex]
[tex]f(2)=\ln12\approx2.485[/tex]
so [tex]f[/tex] attains a maximum value of [tex]\ln12[/tex] and a minimum value of [tex]\ln3[/tex].
The absolute minimum of the function f(x) = ln(x2 + 2x + 4) is at x=-2 where the value is ln(4) and the absolute maximum is at x=2 where the value is ln(8). There are no critical numbers within the selected interval.
Explanation:The given function is
f(x) = ln(x
2
+ 2x + 4)
, for which we need to find the absolute maximum and minimum in the interval [-2, 2]. Firstly, we find the derivative of the function:
f '(x) = (2x + 2) / (x
2
+ 2x + 4)
. To find the critical points, we set the derivative equal to zero and solve for x, finding no real solutions, indicating there are no critical numbers within the given interval. Thus, the extrema must occur at the endpoints. So, we find f(-2) = ln(4) and f(2) = ln(8).
The absolute minimum is ln(4) at x = -2 and the absolute maximum is ln(8) at x = 2

We can use the fact that, for [tex]|x|<1[/tex],
[tex]\displaystyle\frac1{1-x}=\sum_{n=0}^\infty x^n[/tex]
Notice that
[tex]\dfrac{\mathrm d}{\mathrm dx}\left[\dfrac1{1-x}\right]=\dfrac1{(1-x)^2}[/tex]
so that
[tex]f(x)=\displaystyle\frac5{(1-x)^2}=5\frac{\mathrm d}{\mathrm dx}\left[\sum_{n=0}^\infty x^n\right][/tex]
[tex]f(x)=\displaystyle5\sum_{n=0}^\infty nx^{n-1}[/tex]
[tex]f(x)=\displaystyle5\sum_{n=1}^\infty nx^{n-1}[/tex]
[tex]f(x)=\displaystyle5\sum_{n=0}^\infty(n+1)x^n[/tex]
By the ratio test, this series converges if
[tex]\displaystyle\lim_{n\to\infty}\left|\frac{(n+2)x^{n+1}}{(n+1)x^n}\right|=|x|\lim_{n\to\infty}\frac{n+2}{n+1}=|x|<1[/tex]

The Maclaurin series for the function 5(1 − x)⁻² is obtained by applying the binomial series theorem, resulting in the series: 5*(1 + 2x - 2 + 3x² - 3x + 4x³ - 4x² + ...). The radius of convergence for the series is 1.
Explanation:The function given is f(x) = 5(1 − x)−2. The Maclaurin series of a function f is the expression of that function as an infinite sum of terms calculated from the values of its derivatives at a single point. Here, we can use the binomial theorem as a starting point. It states that (1+x)ⁿ = 1 + nx + (n(n-1)/2!)x² + ..., where n is a real number and -1
Now, f(x) is similar to the binomial series: if we let n=-2, and x become -(x-1), we have f(x) = 5(1 – x)⁻² = 5*(1 + 2(x-1) + 3*(x-1)² + 4*(x-1)³ + ...)
So the Maclaurin series for the function is: 5*(1 + 2x - 2 + 3x² - 3x + 4x³ - 4x² + ...). The next step is to find the radius of convergence. The series has a radius of convergence R such that for all x in the interval -R

Sammy's dog eats 3/4 cup of food at each meal. His cat eats 1/8 of that.
This comes out to (1/8)th of (3/4 cup), or:
1 3
----- · ----- cup = 3/32 cup
8 4
The cat eats 3/32 of a cup of food.
Final answer:
Sammy's cat eats 3/32 cup of food per meal, which is calculated by multiplying the dog's portion, 3/4 cup, by 1/8.
Explanation:
Solving the question involves a basic understanding of fractional multiplication. Since Sammy's cat eats 1/8 of what the dog eats, we calculate the cat's portion by multiplying the dog's portion by 1/8.
Sammy's dog eats 3/4 cup of food at each meal. To find out what fraction of a cup Sammy's cat eats, we multiply 3/4 by 1/8.
Here's the calculation: 3/4 × 1/8 = 3/32
Therefore, Sammy's cat eats 3/32 cup of food at each meal.

If cos x = 2 / 3 and x is in quadrant 4, find:
a. sin(x / 2)
b. cos(x / 2)
c. tan(x / 2)
Answer:
A
Step-by-step explanation:
cos(x)=2/3 in Q 4
sin(x/2)=+√(1-cos(x))/2
√(1-cos(x))/2=√(1-[2/3]/2=√(1/3)/2=-√(1/6) because sin is negative in Q 4
Answer:
See below.
Step-by-step explanation:
Because cos x = 2/3 the adjacent side = 2 and hypotenuse = 3 so the length of the opposite side =
√(3^2 - 2^2) = -√5 (its negative because we are in Quadrant 4).
So sin x = -√5/3.
(a) sin (x /2) = - √ [ (1 - cos x)/2 ]
= -√(1 - 2/3)/ 2)
= -√(1/6). or -0.4082.
(b) cos (x/2) = √ [ (1 + cos x)/2]
= √ 5/6 or 0.9129.
(c) tan (x /2) = ( 1 - cos x) / sin x.
= ( 1 - 2/3) / -√5/3
= -0.4472.

The triangle shown in the image attached is a right triangle.
Therefore, to calculate the missing lenght of the triangle you can apply the Pythagorean Theorem, which is shown below:
[tex]a^2=b^2+c^2[/tex]
Where a is the hypotenuse and b and c are the legs.
The problem gives you the value of the hypotenuse and the value of one leg. Therefore, you must solve for the other leg from [tex]a^2=b^2+c^2[/tex], as following:
[tex]17^2=15^2+c^2\\c=\sqrt{17^2-15^2}\\c=8[/tex]
Therefore, the lenght of the missing side is: 8
Answer:
The value of third side= 8 units
Step-by-step explanation:
It is given a right angled triangle with base = 15 and hypotenuse = 17
We have to find the height of given triangle.
Points to remember
By Pythagorean theorem
Base² + Height² = Hypotenuse²
To find the third side
Here base = 15 and hypotenuse = 17
We have,
Base² + Height² = Hypotenuse²
Height² = Hypotenuse² - Base² = 17² - 15² = 64
Height = √64 = 8 units
Therefore the value of third side = 8 units

An artist wants to paint a mural. She mixes blue paint and red paint to make paint that is a certain shade of purple. The ratio of blue paint to red paint should be 3 to 2. She needs 20 gallons of the purple paint. How much more blue paint than red paint does she need?
Answer:
She needs 4 more gallons of blue paint than red paint
Step-by-step explanation:
Since the ratio is 3 to 2, 3 + 2 = 5.
The artist needs 20 gallons of purple paint, so 20/5 = 4
The amount of blue and red paint needed is 4x3 to 4x2, or 12 to 8.
She needs 12 gallons of blue paint and 8 gallons of red paint.
