Answer:
Subtract 36 and 16
Step-by-step explanation:
16 + b^2 = 36
Subtract 16 from each side
16+b^2 -16 = 36-16
b^2 = 20
Take the square root of each side
sqrt(b^2) = sqrt(20)
b = sqrt(20)

Hint: Remember to rationalize the denominator.
Answer:
[tex]\rm \dfrac{\sqrt2}{2}[/tex]
Step-by-step explanation:
A right angled ∆ is given to us and we need to find out the value of cos 45° ( with rationalized denominator ) . As we know that in a right angle ∆ , the value of cosine is ,
[tex]\rm\implies cos\theta =\dfrac{base}{hypotenuse} [/tex]
In the given triangle ,
Value of base = 1 Value of hypotenuse = √2On substituting the respective values ,
[tex]\rm\implies cos45^\circ =\dfrac{1}{\sqrt2} [/tex]
For rationalizing the denominator , multiply numerator and denominator by √2 , we have,
[tex]\rm\implies cos45^\circ=\dfrac{1(\sqrt2)}{(\sqrt2)(\sqrt2)} [/tex]
Simplify ,
[tex]\rm\implies \boxed{\pink{\frak{ cos45^\circ=\dfrac{\sqrt2}{2} }}}[/tex]

Find the measures of the following angles
Answer:
HGD: 117
FDG: 180
Step-by-step explanation:
Answer:
<HDG = 117 degrees
<FDG = 63 degrees
Step-by-step explanation:
Its a straight line
These are supplementary angles
If its a striaght line its 180 degrees.
We already know theres a 63 degrees so we jsut gotta subtract
180-63=117
So 117 degrees for HDG

if you sold 60 cups of lemonade , how many cups of orange drink did you sell
Answer: 0, I think, hope this helps
Step-by-step explanation:
Answer:
you sold 40 cups of orange drink.
Step-by-step explanation:
60*2=120 (the cups of lemonade, multiplied by the cost equals how much you earned from lemonade.)
240-120=120 (how much you earned total, minus 120, how much you earned from lemonade, equals the remainder, how much total you earned for the oragne drinks. )
120/3=40 (the amount you earned for the orange drinks, divided by three, how much you earned for each, which equals 40. and equation would be
240=2x+3y
240=2(60)+3y
240=120+3y
240-120=120-120+3y
120=3y
120/3=3y/3
40=y

2) translation: 2 units up
Q(-4,-2), R(-4,-2), s(0, -2), t(-3-5)
Answer:
Q'(-4,0), R'(-4,1), S'(0,0), T'(-3,-3)
Step-by-step explanation:
To solve this, what we need to do is find out what the translation is. So if we are translating those coordinates up two units, then that means we are basically adding two to the y value.
So that means that we will use the mapping (x,y)→(x,y+2)
Now we plug this in. We will start with Q:
Q(-4,-2)→Q'(-4,-2+2)→Q'(-4,0)
So when Q is translated two units up, we get Q'(-4,0).
Now we will do R:
R(-4,-1)→R'(-4,-1+2)→R'(-4,1)
So when R is translated two units up, we get R'(-4,1).
Now we will do S:
S(0,-2)→S'(0,-2+2)→S'(0,0)
So when S is translated two units up, we get S'(0,0).
Next we will do T:
T(-3,-5)→T'(-3,-5+2)→T'(-3,-3)
So when T is translated two units up, we get T'(-3,-3).

5 2.5 is the slope
6 -0.5
7 no slope
Step-by-step explanation:
1 no because the y overlaps
2 not sure
3 it over laps
4 it never overlaps
5 y=2.5x-3
6 y=-0.5x+1
7 no slope it's just x=-2
for the 5-7 you can type that into demos and get more info
y=mx+b
m is the slope and b is y intercept

6. Write the following cubes in expanded form:
(iii) (3a + 4b)³
8. Evaluate the following cubes using suitable Identities:
(ii) (999)³
Answer:
Step-by-step explanation:
we can use this algebraic identity:
[tex](a+b)^{3} =a^{3} +b^{3} +3ab(a+b)[/tex]
So,[tex](3a+4b)^{3} =(3a)^{3} +(4b)^{3}+3(3a)(4b)(3a+4b)[/tex]
=[tex](3a+4b)^{3} =27a^{3} +64b^{3} +36ab(3a+4b)[/tex]
=[tex](3a+4b)^{3} =27a^{3} +64b^{3} +108a^{2} b+144ab^{2}[/tex]
[tex](999)^{3}[/tex]=[tex](1000-1)^{3}[/tex]
Now, we can use the following identity:
[tex](a-b)^{3} =a^{3} -b^{3} -3ab(a-b)[/tex]
=[tex](1000-1)^{3} =1000^{3} -1^{3} -3(1000)(1)(1000-1)\\[/tex]
[tex](1000-1)^{3} =1,000,000,000-1-2,997,000[/tex]
[tex](1000-1)^{3} =997,002,999[/tex]

=============================================================
Explanation:
Let's say x is the measure of angle 1, aka angle ABC. We'll also say the variable y is equal to angle 2, aka angle CBD.
Angles x and y add to angle ABD, which is 95 degrees
x+y = 95
Since angle 2 is four times that of angle 1, we also know that,
y = 4x
----------------
Let's apply substitution to solve for x
x+y = 95
x+4x = 95 ... replace y with 4x
5x = 95
x = 95/5
x = 19 which is the measure of angle 1
y = 4x = 4*19 = 76
x+y = 19+76 = 95 which helps confirm the correct answer.
