16-2t=5t+9?????????????????????????????????????
Answers
Answer:
t=1
Step-by-step explanation:
16-2t=5t+9 (add 2t)
16=7t + 9 (subtract 9)
7=7t (divide 7)
t=1
Answer:
t=1
Step-by-step explanation:
step one : rearrange terms
16−2=5+9
−2+16=5+9
step two: subtract 16 from both sides of the equation
−2+16=5+9
−2+16−16=5+9−16
step three: simplify
−2=5−7
step four:Subtract 5t from both sides of the equation
−2=5−7
−2−5=5−7−5
step five: combine like terms
−7=−7
step six: divide
−7 /−7 =−7/−7

5 - 2 (4а + 1) - За - 13 I need help
Answers
Answer:
-11a - 10
Step-by-step explanation:
simplify in order of terms: -2(4a + 1) - 3a - 13 + 5
simplify: -8a - 2 - 3a - 8
simplify again: -11a - 10
5 -8a -2 - 3a - 13
3 - 11a - 13
-10 - 11a
and if you want to solve for a:
-10 - 11a = 0
-11a = 10
a = -10/11

Geometry Angle of elevation/depression
Answers
Answer:
m∠ACB = 49.88°
Step-by-step explanation:
From the figure attached,
Measure of wire AC attached to the top 'C' of the building BC = 340 m
Horizontal distance between the base 'B' of the building and point A = 260 m
Angle of depression = ∠ACB
By applying sine rule in the given triangle,
sin(∠ACB) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{AB}{BC}[/tex]
= [tex]\frac{260}{340}[/tex]
m∠ACB = [tex]\text{sin}^{-1}(764706)[/tex]
= 49.88°

4. Neither x nor y can appear in a denominator
Answers
The statement that is false is:
"The variables x and y can be multiplied together"
Which statement is not true?
The general linear equation is given by:
y = a*x +b
Where a is the slope and b is the y-intercept.
The statement that is evidently false about the above general equation is:
"The variables x and y can be multiplied together"
y depends linearly on x, so these variables can't be multiplied together.

Use SOH CAH TOA to recall how the trig functions fit on a triangle
SOH: Sin(Ф)= Opp / Hyp
CAH: Cos(Ф)= Adj / Hyp
TOA: Tan(Ф) = Opp / Adj
now fine one of the above functions that has the 3 things you are working with. 2 knowns, and 1 unknown
also we know that the angle at the right tip of the triangle is 90-59= 31°
we know that b/c the inside angles of a triangle always add to 180 and there is already a 90° so we only have 80 left, which the 59° is part of, so 31 is the other, now put that info into one of the above formulas
x= adjacent side
and we know the angle and hypotenuse side. find the formula with those parts. I see Cos has those or CAH... to help remember how those fit
Cos(31) = x / 17
17*cos(31) = x

how to write the radical √8 using rational exponents?
Answers
Answer:
2√2
Step-by-step explanation:
√8 can be simplified to √(4)(2) , since 4 x 2 still equals 8. But now, 4 is a perfect sqaure, and whenever we get a perfect sqaure, we divided it by its root and put that number on the outside.
For ex: √32 = √(16)(2), since 16 x 2 = 32. 16 is a perfect sqaure, so we take its root and put it on the outside 4√2 ,
Now with this one, we'll do the same thing: √(4)(2) = 2√2

A sample of a radioactive isotope had an initial mass of 360 mg in the year 1998 and
decays exponentially over time. A measurement in the year 2004 found that the
sample's mass had decayed to 270 mg. What would be the expected mass of the
sample in the year 2011, to the nearest whole number?
Answers
Answer:
193 mg
Step-by-step explanation:
Exponential decay formula:
[tex]A_t = A_0e^r^t[/tex]where Aₜ = mass at time t, A₀ = mass at time 0, r = decay constant (rate), t = timeOur known variables are:
1998 to the year 2004 is a total of t = 6 years.The sample of radioactive isotope has an initial mass of A₀ = 360 mg at time 0 and a mass of Aₜ = 270 mg at time t.Let's solve for the decay constant of this sample.
[tex]270=360e^-^r^(^6^)[/tex][tex]270=360e^-^6^r[/tex] [tex]\frac{3}{4} =e^-^6^r[/tex][tex]\text{ln} (\frac{3}{4} )= \text{ln}(e^-^6^r)[/tex] [tex]\text{ln} (\frac{3}{4} )=-6r[/tex] [tex]r=-\frac{\text{ln}\frac{3}{4} }{6}[/tex] [tex]r=0.04794701[/tex]Using our new variables, we can now solve for Aₜ at t = 7 years, since we go from 2004 to 2011.
Our new initial mass is A₀ = 270 mg. We solved for the decay constant, r = 0.04794701.
[tex]A_t=270e^-^(^0^.^0^4^7^9^4^8^0^1^)^(^7^)[/tex] [tex]A_t=270e^-^0^.^3^3^5^6^2^9^0^7[/tex][tex]A_t=193.01982213[/tex]The expected mass of the sample in the year 2011 would be 193 mg.

∠ XNM and ∠ XKL are alternate angles and are congruent, then
∠ XNM = 35°
The sum of the 3 angles in a triangle = 180° , so
∠ XMN = 180° - (95 + 35)° = 180° - 130° = 50°

Answers
Answer: 17
Step-by-step explanation:
We can tell that for every 2 changes in X there is 8 points lost in y
meaning that if we do 8 /2 we get 4
Every 1 change in x there is 4 points of change in Y
so if (3,5) Then (0,17)
17 - 5 = 12 And 3-0 = 3 So for 3 points of change for Xthere were 12 points of change for Y so this is right
x+(y+1) divided by 5
Answers
Answer:
uhm so you'd assume y is more than 5 so maybe try x +(7+1) /5
now do x + 8 /5. x must be like 7 so
x= 7 and y= 7 so it is 7 + (7+1) divided by 5 which is 3 I believe
simplifying it just as is is more like x + (y+1) / 5

Answer:
f(n) = 2 × [tex]3^{n-1}[/tex]
Step-by-step explanation:
In order to write an explicit rule for a geometric function, you need to know the common ratio; you can find the common ratio by dividing two consecutive terms:
6 ÷ 2 = 3, 18 ÷ 6 = 3, 54 ÷ 18 = 3, etc..
Now you know the common ratio is 3. At this point you can write your explicit function following the rule f(n) = [1st term] × [common ratio]^(n-1):
f(n) = 2 × 3^(n-1)

Someone help and please make sure it’s right
Answers
Answer:
20°
Step-by-step explanation:
Look at the attached photo.
∠a and ∠e are equal because they are vertical angles.
So, m∠a = 110°
Then, ∠f is an exterior angle to angles a and c. So,
m∠f = m∠a + m∠c
Substitute and solve.
130 = 110 + m∠c
m∠c = 20°
Then, ∠c and ∠d are vertical angles so they are equal.
m∠c = m∠d
m∠d = 20°
