The height of △XYZ is the distance from point Yto XZ←→. Find the area of the triangle. Round your answer to the nearest tenth, if necessary.
Answers
Answer:
10
Step-by-step explanation:
A triangle is a polygon shape with three sides. There are different types of triangles such as scalene, obtuse, equilateral, isosceles etc.
The area of a triangle is given by:
Area = (1/2) * base * height
For triangle XYZ, the base = |XZ| and the height = |AY|
We can calculate the base and height using the formula for the distance between two points [tex]A(x_1,y_1)\ and\ B(x_2,y_2)\ on \ the\ coordinate\ plane[/tex]
[tex]|AB|=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Therefore:
[tex]Base=|XZ|=\sqrt{(0-(-2))^2+(2-6)^2} =\sqrt{20} \\\\Height=|AY|=\sqrt{(3-(-1))^2+(6-4)^2}=\sqrt{20}[/tex]
Area = (1/2) * base * height = (1/2) * √20 * √20 = 10.

the sliding board is 15 feet long and meets the ground at a 40 degree angle. what is the height of the ladder?
Answers
Answer:
9.6 ft
Step-by-step explanation:
Sin=opposite/hypotenuse
The required height of the ladder is 9.6 feet.
Given that,
The sliding board is 15 feet long and meets the ground at a 40-degree angle.The height of the ladder is to be determined.
These are the equation that contains trigonometric operators such as sin, cos.. etc.. In algebraic operation.
Here,
Let the height of the ladder be p
Now, applying trigonometric operations,
sin 40 = p / 15
p = 15 sin40
p = 0.64 * 15
p = 9.6
Thus, the required height of the ladder is 9.6 feet.

x- y= 4( equation 1)
xy=45( equation 2)
From equation 1
x= 4+y( equation 3)
put equation 3 into equation 2
( 4+y)y=45

find the Sum of two consecutive odd numbers plus eighteen is 170
Answers
Answer:
75, 77
Step-by-step explanation:
Let the first odd number = 2x -1
Let the second odd number = 2x + 1
2x - 1 + 2x + 1 + 18 = 170 Combine like terms on the left.
4x + 18 = 170 Subtract 18 from both sides.
4x = 170 - 18 Combine like terms on the right
4x = 152 Divide by 4
4x/4 = 152/4
x = 38
2 * 38 - 1 = 75
2 * 38 + 1 = 77
Sarah made a certain number of bracelets for a craft show. Maria made 7 more than Sarah. Julie made 3 times as many as Maria. Which expression represents the total number of bracelets Julie made if Sarah made s bracelets?
Answers
Answer:
Total no of bracelets = 5s+28
Step-by-step explanation:
Let Sarah made s bracelets.
Maria made 7 more than Sarah i.e. 7+s
Julie made 3 times as many as Maria i.e. 3(7+s)
Total no of bracelets made is equal to the sum of the bracelets made by Sarah, Maria and Julie.
Total = s+ 7 + s + 3(7+s)
= 2s+7+21+3s
=2s+3s+21+7
= 5s+28
So, there are (5s+28) bracelets.

Write the explicit formula for the arithmetic sequence 11, 14, 17, 20, . . . What is term number 54 in this sequence?
Answer:
Answers
Answer:
15 or 16. 54 is not listed.
Step-by-step explanation:
pretend that 11 is 0. that means 54 is 43.
then you do 43 divided by 3 or 43/3
but looks like the number 43 isn't divisible. it is 14.33333 repeating decimal.
Same if you really use your time and count. So i dont know if u meant 53 it will be 53 if you meant 56 it will be 16.
Answer:
see explanation
Step-by-step explanation:
The explicit formula for an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 11 and d = a₂ - a₁ = 14 - 11 = 3, then
[tex]a_{n}[/tex] = 11 + 3(n - 1) = 11 + 3n - 3 = 3n + 8
Thus
a₅₄ = 3(54) + 8 = 162 + 8 = 170
