is right answer
is that true that r is the set of counting numbers from 7 to 12 is in a roster notation
the measures of the three angles of a triangle is 180
in a triangle, the measures of the three angles are x, x + 18, and x - 6. what is the measure of each angle
Answer:
X + X +18 + X-6 = 180
3x + 12 = 180
3x = 168
x= 56
x + 18 = 74
x - 6 =50
Step-by-step explanation:
Answer:
56°, 74°, 50°
Step-by-step explanation:
x + x + 18 + x - 6 = 180
3x + 12 = 180
3x = 168
x = 56
56 + 18 = 74
56 - 6 = 50
The next number in the arithmetic sequence 10, 23, 36, __is:
49.
46.
43.
50.
Answer:
49
Step-by-step explanation:
Answer:
49
Step-by-step explanation:
From the sequence it is obvious that the next number was simply the addition of 13, so by adding 13 to 36 we get 49
There is a rope hanging from the top of a pole with 3 feet of it lying on the ground. When it is tightly stretched, so that the end just touches the ground, it reaches a point 8 feet from the base of the pole. How long is the rope
Answer:
length of rope [tex](P+3) =12.167[/tex]
Step-by-step explanation:
From the question we are told that
Length of rope on Ground [tex]L_1=3 feet[/tex]
Length of rope from pole base when stretched [tex]L_2=8feet[/tex]
Given length of pole as P
length of the rope is therefore given by
[tex]P+3[/tex]
Generally the Pythagoras theorem is mathematically given by
[tex]P^2+8^2=(P+3)^2[/tex]
[tex]P^2+64=P^2+9[/tex]
[tex]P=9.167[/tex]
Therefore
length of rope [tex]P=9.167[/tex]
length of rope [tex](P+3) =9.167+3[/tex]
length of rope [tex](P+3) =12.167[/tex]

Answer:
see belowStep-by-step explanation:
to understand thisyou need to know about:algebraPEMDASlet's solve:given function:
[tex] \quad \rm\: f(x) = - 2x +8[/tex]
when x is 0
[tex] \sf \:f(0) = - 2.0 + 8[/tex]
simplify multiplication:
[tex] \sf f(0) = 8[/tex]
when x is 3
[tex] \sf f(3) = - 2.3 + 8[/tex]
simplify multiplication:
[tex] \rm \: f(3) = - 8 + 8[/tex]
add:
[tex] \rm \: f(3) = 0[/tex]
when x is 6
[tex] \quad \rm\: f(6) = - 2.6 +8[/tex]
simplify multiplication:
[tex] \quad \rm\: f(6) = - 12 +8[/tex]
simplify addition:
[tex] \quad \rm\: f(6) = -4[/tex]
when x is 9:
[tex] \quad \rm\: f(9) = - 2.9 +8[/tex]
simplify multiplication:
[tex] \quad \rm\: f(9) = - 18 + 8[/tex]
simplify addition:
[tex] \quad \rm\: f(9) = - 10[/tex]
Answer:
when x =0
f(x)=-2×0+8=8
when x =3
f(x)=-2×3+8=2
when x =6
f(x)=-2×6+8=-4
when x =9
f(x)=-2×9+8=-10

1) Complete the sentences to explain how to multiply 4.56 x 1,000.
Y
1) Click the arrows to choose an answer from each menu.
The number 1,000 has Choose... factors of 10. To multiply 4.56 x 1,000, the
decimal point in 4.56 should be moved Choose... places to the right.
4.56 x 1,000 is equal to Choose...
Done
Answer:
The decimal point should be moved 3 units to the right, and the result of the multiplication is 4560.
Step-by-step explanation:
Multiplication of a decimal by the nth power of 10:
In this case, the decimal point should be moved n units to the right.
Division of a decimal by the nth power of 10:
In this case, the decimal point should be moved n units to the left.
In this question:
We multiply the decimal 4.56 by 1000.
1000 is the 3rd power of 10, because [tex]10^3 = 1000[/tex]. So the decimal point should be moved 3 units to the right, and the result of the multiplication is 4560.

Consider the system of equations.
x-3y = 9
1/5 x - 2y = -1
Which number can be multiplied by the second equation to eliminate the x-variable when the equations are added
together?
Given:
The system of equations:
[tex]x-3y=9[/tex]
[tex]\dfrac{1}{5}x-2y=-1[/tex]
To find:
The number that can be multiplied by the second equation to eliminate the x-variable when the equations are added together.
Solution:
We have,
[tex]x-3y=9[/tex] ...(i)
[tex]\dfrac{1}{5}x-2y=-1[/tex] ...(ii)
The coefficient of x in (i) and (ii) are 1 and [tex]\dfrac{1}{5}[/tex] respectively.
To eliminate the variable x by adding the equations, we need the coefficients of x as the additive inverse of each other, i.e, a and -a So, a+(-a)=0.
It means, we have to convert [tex]\dfrac{1}{5}[/tex] into -1. It is possible if we multiply the equation (ii) by -5.
On multiplying equation (ii) by -5, we get
[tex]-x+10y=5[/tex] ...(iii)
On adding (i) and (iii), we get
[tex]7y=14[/tex]
Here, x is eliminated.
Therefore, the number -5 can be multiplied by the second equation to eliminate the x-variable.

Write the log equation as an exponential equation. You do not need to solve for x.
log (x^2– 5x + 14) = 2x + 4
9514 1404 393
Answer:
x^2 -5x +14 = 10^(2x +4)
Step-by-step explanation:
The relationship is ...
log(a) = b ⇔ a = 10^b
__
Using this with a=x^2-5x+14 and b=2x+4, we have ...
x^2 -5x +14 = 10^(2x +4)

Additional comments
In plain text, the exponent needs parentheses, because superscript formatting is not available to tell what is and isn't part of the exponent.
The base of "log" is assumed to be 10 in high school algebra. In the larger world, "log" is often used in place of "ln" to mean the logarithm to base 'e'.

The one solution is approximately x = −1.32505947996.
