Explain why they substituted cos(60) with 1/2 ?
(Look at image)
9514 1404 393
Answer:
equals can be substituted anytime anywhere
Step-by-step explanation:
cos(60°) = 1/2, so wherever one appears, the other can be substituted. This is allowed by the substitution property of equality.
__
If you don't substitute at some point, you find the answer to be ...
x = 10/cos(60°)
Most of us are interested in a numerical value for x, so we prefer that cos(60°) be replaced by a numerical value.

If a car travels at a uniform speed at 72 kilometers per hour, how many kilometers does it travel in 15
minutes?
Answer:
18 kilometres
Step-by-step explanation:
Speed of the car is 72 kilometres per hour
means the car runs 72 kilometers within 60 minutes
so, the car will travel in 15 mins,
72×15/60
= 72/4 = 18 kilometres
A car start from rest . If the acceleration of the car is 0.2m/s^2, what will be it's velocity at the end of 3 minutes?And what distance will it cover at that time?
Answer:
a=v-u÷t
0.2=v-0÷180
0.2×180=v
36=v
Given g(x) = -x + 4, find g(5).
Answer:
g(5) = -1
Step-by-step explanation:
Let x = 5.
[tex]g(5)=-(5)+4\\g(5)=-5+4\\g(5)=-1[/tex]
Answer:
-1
Step-by-step explanation:
g(x)= -x+4
then substitute 5 on x
=-(5)+4=-1
Line A is represented by the following equation: X + y = 2
What is most likely the equation for line B so the set of equations has no solution?
Answer:
x+y=3
Step-by-step explanation:
For an equation to have no solution, their slope needs to be same and y intercept needs to be different,
so in this case where x+y=2
doing simply, x+y=3 makes a set of equation which has no solution, you can take any real value which is not 2

Step-by-step explanation:
K(x)=5^(x+2)
Let x = -2
K(-2)=5^(-2+2)

Answer:
k(- 2) = 1
Step-by-step explanation:
Substitute x = - 2 into k(x) , that is
k(- 2) = [tex]5^{-2+2}[/tex] = [tex]5^{0}[/tex] = 1 [ [tex]a^{0}[/tex] = 1 ]

Step-by-step explanation:
a golf course is trying to determine par for a particular hole. calculate the value they should put on the sign where people tee off so they know what par is for this hole.
The value they should put on the sign where people tee off so they know
what par is for the hole is six (6)
The reasoning through which the correct answer is arrived at is presented here given table of values which is presented as follows;
[tex]\left[\begin{array}{ccc}Golf \ Strokes \ (x)&Frequency \ (f) & f \times x\\2&16& 32\\3&21&63\\4&23&92\\5&20&100\\6&54&324\\7&40&280\\8&23&184\\9&16&144\\\sum&213&1,219\end{array}\right][/tex]
The mean number of golf strokes for the hole is ∑(f·x)/∑f
The calculation for f × x on the table includes;
∑(f·x) = (2×16 + 3×21 + 4×23 + 5×20 + 6×54 + 7×40 + 8×23 + 9×16) = 1219
∑f = 16 + 21 + 23 + 20 + 54 + 40 + 23 + 16 = 213
∴ ∑(f·x)/∑f = 1,219/213 = 5.72 ≈ 6
The mean number of golf strokes expected is approximately 6 strokes
The value they should put on the sign where people tee off so they know what par is for the hole is 6

prove that root 3 + root 7 is irrational
Answer:
√3+√7 is irrational.
Step-by-step explanation:
Let us assume that √3+√7 is rational.
That is , we can find coprimes a and b (b≠0) such that \sqrt{3}+\sqrt{7}=\sqrt{a}{b}

Therefore,
\sqrt{7}=\frac{a}{b}-\sqrt{3}

Squaring on both sides ,we get

is rational ,and so √3 also rational.
But this contradicts the fact that √3 is irrational.
This contradiction has arisen because of our incorrect assumption that √3+√7 is rational.
Hence, √3+√7 is irrational.

Someone please helpp
Answer:
The two equations are similar because they both end up with the same common value. 0=0 The work you need to show that this is correct will be shown below.
Step-by-step explanation:
2(5m−4)−3(m−5)2=−3m2+40m−83
Add 3m^2 to both sides.
−3m2+40m−83+3m2=−3m2+40m−83+3m2
40m−83=40m−83
Subtract 40m from both sides.
40m−83−40m=40m−83−40m
−83=−83
−83+83=−83+83
0=0

Since round to the nearest one is too vague, i'll give everything this can be rounded too
Rounded to the nearest whole number
0.741 = 1
Rounded to the nearest tenth
0.741 = 0.7
Rounded the the nearest hundreth

What is the area of the rhombus?
360 squared centimeter.
Answer:
Step-by-step explanation:
(-6 , 1) & (8 , 1)
d1 = 8 + I - 6I = 8 + 6 = 14
(1,6) & (1 , -4)
d2 = 6 + I -4 I = 6 + 4 = 10
Area of rhombus = [tex]\frac{d_{1}*d_{2}}{2}[/tex] where d1 & d2 are the diagonals
[tex]\frac{14*10}{2} = 7 * 10 = 70 \ square \ units[/tex]
