Answer:
a) root77
b) 2 root77 / ~17.55 cm^2
Step-by-step explanation:
a) by using Pythagorean Theroem,
a^2 + b^2 = c^2
2^2 + b^2 = 9^2
4 + b^2 = 81
81 - 4 = b^2
77 = b^2
root77 = b
b) 1/2bh is the quation for area thus,
area = 1/2 ( 4 ) ( root77)
area = 2 root77
or area = ~17.55 cm^2
h = [tex]\sqrt{77}[/tex]
A =[tex]2\sqrt{77}[/tex]
Step-by-step explanation:Rules for solving this problem:
Isosceles triangle rules
∠C = ∠ABC = BABecause of isosceles being made up of two right triangles; using the pythagorean theorem we can deduce that
(1/2 x AC)² = BC² - h² (1/2 x AC)² = BA² - h²Area of a triangle
A = 1/2 (Base x Height) = 1/2 * bhStep 1 - Find the height
[tex]h =\sqrt{9^2 - ((1/2)AC)^2} = \sqrt{9^2 - ((1/2)~4)^2} = \sqrt{9^2 - 2^2} = \sqrt{81-4} = \sqrt {77}[/tex]
Step 2 - Find the area
[tex]A = \frac{1}{2}bh = (\frac{1}{2})(4)(\sqrt{77}) = 2 \sqrt{77}[/tex]

What is the greatest common factor of 42 and 14?
Answers
It is 14 because if you do prime factorization:
14 = 2 x 7
42 = 2 x 3 x 7
They have the factors 2 and 7 in common.
2 x 7 = 14.
Answer:
The GCF is 14!
Step-by-step explanation: Okay Lets multiply to get 42, 14 x 1 is 14, 14 x 2 is 28, 14 x 3 is 42! We also know that this is the GCF because 42 and 14 can both be divided by 14!
the function g(x) represents f(x)=9 cos (x-pi/2)+3 after translating pi/6 units left and 4 units up. which equation represents g(x)?
g(x)= 9 cos (x - 2pi/ 3) -1
g(x)= 9 cos (x - 2pi/3) +7
g(x)= 9 cos (x - pi/3) +7
g(x)= 9 cos (x - pi/3) -1
Answers
Answer:
g(x)= 9 cos (x - [tex]\frac{\pi}{3}[/tex]) +7
Step-by-step explanation:
What is given is f(x) = g cos (x - pi/2) + 3
Note that the standard form of cosine function is a cos (bx + c) + d
a= amplitude
-c/b = phase shift
d = vertical shift
After moving pi/6 to the left --
x = pi/2 - pi/6 = pi/3
once moving pi/6 left, it is at pi/3
moving 4 units up just means adding 4 + 3, and that equals 7, that would be the vertical shift once applied.
So the equation that represents g(x) is C. 9 cos (x - pi/3) + 7
The equation that represents the function g(x) is [tex]g(x)=9 \cos (x- \frac{\pi}{3})+7[/tex]
The function is given as:
[tex]f(x)=9 \cos (x-\frac{\pi}{2})+3[/tex]
The function f(x) is first translated [tex]\frac{\pi}{6}[/tex] units left.
The rule of this translation is:
[tex](x,y) \to (x + \frac{\pi}{6},y)[/tex]
So, we have:
[tex]f'(x)=9 \cos (x+ \frac{\pi}{6}-\frac{\pi}{2})+3[/tex]
Take LCM
[tex]f'(x)=9 \cos (x+ \frac{\pi - 3\pi}{6})+3[/tex]
[tex]f'(x)=9 \cos (x- \frac{2\pi}{6})+3[/tex]
Divide 2 by 6
[tex]f'(x)=9 \cos (x- \frac{\pi}{3})+3[/tex]
Next, we translate f'(x) 4 units up.
The rule of this translation is:
[tex](x,y) \to (x,y+4)[/tex]
So, we have:
[tex]g(x)=9 \cos (x- \frac{\pi}{3})+3 +4[/tex]
[tex]g(x)=9 \cos (x- \frac{\pi}{3})+7[/tex]
Hence, the equation that represents the function g(x) is [tex]g(x)=9 \cos (x- \frac{\pi}{3})+7[/tex]

taking angle C let interior angle be Z
Again, In angle A
the sum of interior angle and exterior angle is 180 degree being staright line
Or, y+(x+5)=180

THINK SMARTER Margot wants to use partial products to find 22 X 17.
Write the numbers in the boxes to show 22 X 17-
Answers
Answer:
( 20 × 10 ) + ( 20 × 7 ) + ( 2 × 10 ) + ( 2 × 7 )
Step-by-step explanation:
To create partial products when multiplying two numbers, first break the numbers up into a sum of two numbers. The order that these numbers are multiplied does not necessarily matter as long as they are multiplied with the correct numbers.
22 × 17 = (20 + 2)(10 + 7) = 20 (10 + 7) + 2 (10 + 7) =
( 20 × 10 ) + ( 20 × 7 ) + ( 2 × 10 ) + ( 2 × 7 )
= 374
You can check this method works by using your calculator, and multiplying 22 by 17 to get 374 again!
Then just add like you would if when you distribute.

What is the right triangle?A right triangle is defined as a triangle in which one angle is a right angle or two sides are perpendicular.
In any equilateral triangle, the three angles are of equal measure and they equal 60 degrees.
When we drop a perpendicular that is the height of the triangle we have a 30 -60 90 triangle.
The hypotenuse = 8
Let, perpendicular = a and base = 4
According to Pythagoras theorem,
A right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
perpendicular²+base² = hypotenuse²
a² + (4)² = (8)²
a² + 16 = 64
a² = 64 - 16
a² = 48
a = √48
a = 4√3
Hence, the altitude of the triangle is 4√3

Tickets to an amusement park cost $35 for adults and $20 for children. The equation 35x+20y=140 shows how many adults x and children y can visit the amusement park with $140. If no children go, how many adults can go to the amusement park with $140?
A)7
B)5
C)4
D)2
Answers
Answer: Four adults
Step-by-step explanation: 4 x 35 = 140. There are no children, so you can just ignore 20y (I hope this helps!)
If no children will go to the amusement park then a total of 4 adults can go to the amusement park for $140. Hence, option C is correct.
What is an equation?Equations are logical assertions in mathematics that have two algebraic expressions on either side of an equals (=) sign. The expression on the left and the expression on the right is shown to be equal in reference to one another. LHS = RHS (left hand side = right hand side) appears in all mathematical equations.
You can solve equations to determine an unknown variable's value, which corresponds to an unknown quantity. It is not an equation if there is no "equal to" sign in the statement.
The given equation is :
35x + 20y = 140
Cost of adults to go to the amusement park, (x) = $35 and,
Cost of children going to the amusement park, (y) = $20.
If no children are going to the amusement park, then the number of adults who can go to the park is :
35x + 20(0) = 140
35x = 140
x = 140/35
x = 4.
Hence, this concludes that option C is correct.
