The statement " Any altitude of an equilateral triangle is also a median of the triangle " is true
because if we take altitude from any side of an equilateral triangle to its opposite side. it wil make 90° and by using congruency, the two newly formed truangles will be congruent to each other, hence by using the results of congruency, we can get the two pasrts of the side on which attitude was dropped to be equal.
[tex] \qquad \large \sf {Conclusion} : [/tex]
Yes ! Altitude of an equilateral angle triangle from any side is also a median.
Jose wants to walk to the store from his house but he is not sure how far away it is. Find the distance between his house (-8, -9) and the store (-4, -10). Each unit is equal to one mile.
Answer:
4.12 miles
Step-by-step explanation:
Use distance formula
d^2 = (-8- -4)^2 + ( -9 - -10)^2
d^2 = 16 + 1
d^2 = 17
d = sqrt 17 = 4.12 miles
The centre of the stained glass window is in the shape of a regular polygon. What are the measures of the interior angle of the green triangle?
CAN SOMEONE EXPLAIN WITH REASONING STEP BY STEP Solution so I can grasp the concept easily. please explain with a sol
Answer:
67.5 - 67.5 - 45 °
Step-by-step explanation:
Sum of INTERIOR angles of a polygon
(n-2) * 180 <====ya just have to remember/know this !
n is the number of sides n = 8 in this case
(8-2)*180 = 1080 ° < === this is the SUM of the 8 interior angles
EACH interior angle is then 1080 / 8 = 135 °
you can see from the picture that each of the two outside angles of the green triangle are 1/2 of this = 67.5° each
so the triangle measurements are
67.5 - 67.5 - 45 ( they have to sum to 180 for triangle)

A rectangular box is designed to have a square base and an open top. The volume is to be 500in.3 What is the minimum surface area that such a box can have?
The minimum surface area that such a box can have is 380 square
How to determine the minimum surface area such a box can have?Represent the base length with x and the bwith h.
So, the volume is
V = x^2h
This gives
x^2h = 500
Make h the subject
h = 500/x^2
The surface area is
S = 2(x^2 + 2xh)
Expand
S = 2x^2 + 4xh
Substitute h = 500/x^2
S = 2x^2 + 4x * 500/x^2
Evaluate
S = 2x^2 + 2000/x
Differentiate
S' = 4x - 2000/x^2
Set the equation to 0
4x - 2000/x^2 = 0
Multiply through by x^2
4x^3 - 2000 = 0
This gives
4x^3= 2000
Divide by 4
x^3 = 500
Take the cube root
x = 7.94
Substitute x = 7.94 in S = 2x^2 + 2000/x
S = 2 * 7.94^2 + 2000/7.94
Evaluate
S = 380
Hence, the minimum surface area that such a box can have is 380 square

Note a = 1.
Y =x²-23x² 18x+40
The y factors of the given quadratic equation is -1 and 40/22.
According to the statement
we have given that the equation and we have to find the factors of those equation.
So, The given equation is:
[tex]Y =x^2-23x^2 + 18x+40[/tex]
where y is the factors of that equation.
So, we have to find the factors of the given quadratic equation.
[tex]x^2-23x^2 + 18x+40 = 0[/tex]
Then after solving it become
[tex]-22x^2 + 18x+40 = 0[/tex]
Then take negative sign common from it then
[tex]22x^2 - 18x - 40 = 0[/tex]
Make the factors of this quadratic equation
[tex]22x^2 + 22x -40x - 40 = 0[/tex]
Now take common values 22x and 40 from the equation then
[tex]22x (x + 1) -40 (x + 1) = 0[/tex]
Then it become
[tex](22x - 40) (x + 1) = 0[/tex]
Then the values of x become from the equation is
[tex]x = -1, x= 40/22[/tex]
The value of the factors y is -1 and 40/22.
So, The y factors of the given quadratic equation is -1 and 40/22.

Consider the quadratic equation x2 + 2x - 35 = 0. Solve by factoring and using the zero-product property.
What are solutions to quadratic equations called? Show your work.
Answer:
x = -7
x = 5
Step-by-step explanation:
The standard form of quadratic equations is
Ax^2 + Bx + C = 0
The factors need to multiply together to be C and add together to be B.
The two numbers that will multiply together to be -35 and add together to be 2 are -5 & 7.
The factor pairs are (x+7)(x-5). Zero product property means we set each of those factor pairs = 0 and solve.
x + 7 = 0
-7 -7 Subtract 7 from each side to solve
x = -7
x - 5 = 0
+5 +5 Add 5 to each side to solve
x = 5
To solve the equation, factor x²+2x−35 use the formula x² +(a + b) x + ab = (x + a)(x + b). To find a and b, set up a system to be solved.
a + b = 2
ab = −35
Since ab is negative, a and b have opposite signs. Since a+b is positive, the positive number has a greater absolute value than the negative. Show all pairs of integers whose product is −35.
−1.35−5.7Calculate the sum of each pair.
−1 + 35 = 34−5 + 7 = 2The solution is the pair that gives sum 2.
a = −5b = 7Rewrite the factored expression (x + a)(x + b) with the values obtained.
(x − 5)(x + 7)To find solutions to equations, solve x−5=0 and x+7=0.

Jen opened a savings account at the bank. The amounts of her first 3 deposits are shown below:
• Deposit 1: $325
• Deposit 2: $280
• Deposit 3: $480
• Deposit 4: ?
How much does she need in the fourth deposit so that her average deposit is $365?
Answer:$375
Step-by-step explanation: To find the average, we need to add all of the numbers up and divide by the number of numbers in the set. Since there are 4 deposits, to get an average of #365, Jen needs to have deposited 365x4 = $1460 in total. Now, it is pretty easy to find the answer. We add up her 3 deposits: 325+280+480 = $1085 and see that it is still $375(1460 - 1085) short. So, Jen needs to deposit $375 on her fourth deposit to have an average of $365.

if sin 0=12/13 and 0 is in quadrant II, cos 20= and cos0=
a. The value of cos2θ = -119/169
b. The value of cosθ = -5/13
The question involves trigonometric identities
What are trigonometric identities?Trigonometric identities show the relationship between trigonometric ratios.
How to find the value of cos2θ?Since sinθ = 12/13 and θ is the quadrant II, it means that 90° ≤ θ ≤180° and sinθ is positive.
Using trigonometric identity
cos2θ = 1 - 2sin²θ
Substituting sinθ = 12/13 into the equation, we have
cos2θ = 1 - 2sin²θ
cos2θ = 1 - 2(12/13)²
cos2θ = 1 - 2(144/169)
cos2θ = 1 - 288/169
cos2θ = (169 - 288)/169
cos2θ = -119/169
So, the value of cos2θ = -119/169
How to find the value of cosθ?Since sinθ = 12/13 and θ is the quadrant II, it means that 90° ≤ θ ≤180° and sinθ is positive.
Using trigonometric identity
cosθ = √(1 - sin²θ)
Substituting sinθ = 12/13 into the equation, we have
cosθ = √(1 - sin²θ)
cosθ = √[1 - (12/13)²]
cosθ = √[1 - (144/169)]
cosθ = ±√(169 - 144)/169
cosθ = ±√25/169
cosθ = ±5/13
θ is the quadrant II, it means that 90° ≤ θ ≤180° it means that cosθ is negative.
So, cosθ = -5/13
So, the value of cosθ = -5/13
