Answer:
[tex]14\frac{2}{11}[/tex] ft
Step-by-step explanation:
Let the height of the tree equal x. Shadows are proportional to the height of an object, so we can write a proportion where to numerators are the object and the denominators are the shadow:
[tex]\frac{x}{26} =\frac{6}{11}[/tex]
Now, to solve for x, we can cross-multiply:
11x = 6*26
11x = 156
x = [tex]14\frac{2}{11}[/tex]

Using the midpoint formula
[tex]\left(\frac{-4+5}{2},\:\frac{6+3}{2}\right)[/tex]
=[tex]\left(\frac{1}{2},\:\frac{9}{2}\right)[/tex]
Answer:
Mid point is (0.5, 4.5)
Step-by-step explanation:
Formular:

If f(x)=3x^2-2x+4 and g(x)=5x^2+6x-8,find (f-g) (x)
Answer:
-2x^2-8x+12
Step-by-step explanation:
f(x)=3x^2-2x+4
g(x)=5x^2+6x-8
(f-g) (x)= 3x^2-2x+4 - (5x^2+6x-8)
Distribute the minus sign
(f-g) (x)= 3x^2-2x+4 - 5x^2-6x+8
Combine like terms
=-2x^2-8x+12
Answer:
[tex] - 2( {x}^{2} - 4x + 6)[/tex]
Step-by-step explanation:
[tex] f(x)=3x^2-2x+4 \\ g(x)=5x^2+6x-8 \\ (f-g) (x) = 3 {x}^{2} - 2x + 4 - (5 {x}^{2} + 6x - 8) \\ = 3 {x}^{2} - 2x + 4 - 5 {x}^{2} - 6x + 8 \\ = - 2 {x}^{2} - 8x + 12 \\ = - 2( {x}^{2} - 4x + 6)[/tex]

A polynomial function h(x) has a zero of x = 2 – 5i with a multiplicity of one. Certain values of h(x) are given in the following table.
x h(x)
–5 0
–2 3
–1 –1
1 2
4 0
7 6
10 5
If every real x-intercept of h(x) is shown in the table and each has a multiplicity of one, what is the degree of h(x)?
A. 2
B. 3
C. 4
D. 5
Using function concepts, it is found that the degree of the function is: 4, option C.
----------------------------------------
The x-intercepts of a function are the values of the function for which the output is zero.The degree of a function is the sum of the multiplicities of the x-intercepts of the function.If a function has a complex root, it means that the conjugate is also a root.----------------------------------------
When [tex]x = -5, h(x) = 0[/tex], thus, x = -5 is one x-intercept.When [tex]x = 4, h(x) = 0[/tex], thus, x = 4 is one x-intercept.There is also a x-intercept(zero) at [tex]x = 2 - 5i[/tex]. There will also be a x-intercept at the conjugate, which is [tex]x = 2 + 5i[/tex].Thus, there are 4 x-intercepts, all with multiplicity 1, which means that the degree of h(x) is 4, option C.A similar problem is given at https://brainly.com/question/10539060
Stan's, Mark's, and Wayne's ages are consecutive whole numbers. Stan is the youngest, and Wayne is the oldest. The sum of their ages is 111. Find their ages.
Let Stan's age be x, Mark's age be (x + 1) & Wayne's age be (x + 2).
According to the conditions,⇒x + (x + 1) + (x + 2) = 111
⇒x + x + x + 1 + 2 = 111
⇒3x + 3 = 111
⇒3x = 111 - 3
⇒3x = 108
⇒ x = 108/3
⇒ x = 36
Hence,Stayn's age will be x = 36 years.Mark's age will be (x + 1) = 36 + 1 = 37 years.Wayne's age will be (x + 2) = 36 + 2 = 38 years.▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄how many litters is in a gallon

find the midpoint of the segment with the given endpoints. (2,9) and (-8,-8)
Answer:
The midpoint is (-3, 1/2)
Step-by-step explanation:
To find the x coordinate of the midpoint, add the x coordinates of the endpoint and divide by 2
(2+-8)/2 = -6/2 = -3
To find the y coordinate of the midpoint, add the y coordinates of the endpoint and divide by 2
(9+-8)/2 = 1/2
The midpoint is (-3, 1/2)

Stella and brain each heat up a small pizza.stella cuts her pizza into 4 equal slices. Brain cuts his pizza into 8 equal parts,Stella eats two pieces of her pizza Brian eats four pieces of his pizza do they eat the same amount of pizza? PLEASE ANSWER!!!!
Answer:
They are the same amount of pizza.
Step-by-step explanation:
Stella cut her pizza into 4 pieces. If she eats 2 pieces, then she has eaten half of her pizza. Likewise, Brian cut his pizza into 8 pieces. If he eats 4 pieces, then he has eaten half of his pizza. Therefore, they have both eaten the same amount of pizza.
Model:
6 pounds of apples cost $12 how much do 8 pounds cost?
Answer:
8=$16
Step-by-step explanation:
6=$12
divide both sides by 6
1=$2
so one pound equals $2 so if 6 pounds equals $12 just add 2 pounds to 6 to make it 8 pounds. you added two pounds so that means you have to add $4 to the total witch will give you
8=$16
When commercial aircraft are inspected, wing cracks are reported as nonexistent, detectable, or critical. The history of a particular fleet indicates that 70% of the planes inspected have no wing cracks, 25% have detectable wing cracks, and 5% have critical wing cracks. Five planes are randomly selected. Find the probability that
a. one has a critical crack, two have detectable cracks, and two have no cracks.
b. at least one plane has critical cracks.
Answer:

Add :
-1.25 + 2.5 = 1.25
For plotting the first one we first need to see the integer as here is 1 we will move to 1. Now, here it is given 0.25. Each line between 1 and 2 has 10 numbers gap so, as it 25 > 20 and 25 < 30. So, we should plot it between the 2nd and the 3rd line. As it is 5 it should be in between the line.
Refer the plotting for better identification
Add :
4.2 + (-0.4)
4.2 - 0.4
3.8
For plotting this one we will move to 3 than it has 8 < 10 so it should be plotted within the first dot.

Step-by-step explanation:
I don't know what ON SA means, but here's how I solved it:
(k - 4k + 7) + (k + 9k – 3)
(-3k + 7) + (10k - 3)
(-3k + 10k) + (7 - 3)
