Answer: c
Step-by-step explanation:
if you think about the equations as linear functions, you can imagine that if they do intersect, it must be on only one point (since two straight lines cant intercept at more than one point, unless they are the same line)
therefore the point has to be the one and only intercept- satisfiing both linear equations

Answer:
4ft
Step-by-step explanation:
we will use the formula which states area of triangles is equal to base multiplied height divided by 2
base=5ft
height=8ft
area=5*8/2
=13/2
=6.5ft
this pic is not clear pls mention better next time I was confused what is 4ft and what is 8ft however if I have understood wrong I have also written the formula.

Answers
Answer:
Height of the building = 115.4 ft.
Step-by-step explanation:
Height of building = AB + 46.4 + CD + 30.5
By applying Pythagoras theorem in ΔABP,
(26)² = (10)²+ (AB)²
676 - 100 = AB²
AB² = 576
AB = 24 ft
By applying sine rule in ΔCDE,
cos(60°) = [tex]\frac{CD}{CE}[/tex]
CD = CE × [tex]\frac{1}{2}[/tex]
CD = [tex]\frac{29}{2}[/tex]
CD = 14.5 ft
Total Height = 24 + 46.4 + 14.5 + 30.5
= 115.4 ft

Answers
Answer:
I think that the original price would be $30, but I'm not completely sure.
Step-by-step explanation:
Half (50%) of 40 would be 20, and half of 20 (25%) would be 10. Add 10 to 20 to get 30, because you are adding the %25 back to $20.

The half-life of the isotope Osmium-183 is 12 hours. Choose the equation below that gives the remaining mass of Osmium-183 in grams, M.
after n half-lives have elapsed if there was an initial mass of 590 grams before decay. Then, use the equation to determine the mass remaining
after 36 hours have passed
Mn = 590. ()": M3 – 148
D
M, = 590 C4)*-* : My ~ 148
Mn = 590 - ()": Mz - 74
Mi = 590 - (1) * + : Mz - 74
Answers
The given equations are incomprehensible, I'm afraid...
You're given that osmium-183 has a half-life of 12 hours, so for some initial mass M₀, the mass after 12 hours is half that:
1/2 M₀ = M₀ exp(12k)
for some decay constant k. Solve for this k :
1/2 = exp(12k)
ln(1/2) = 12k
k = 1/12 ln(1/2) = - ln(2)/12
Now for some starting mass M₀, the mass M remaining after time t is given by
M = M₀ exp(kt )
So if M₀ = 590 g and t = 36 h, plugging these into the equation with the previously determined value of k gives
M = 590 exp(36k) = 73.75
so 73.75 ≈ 74 g of Os-183 are left.
Alternatively, notice that the given time period of 36 hours is simply 3 times the half-life of 12 hours, so 1/2³ = 1/8 of the starting amount of Os-183 is left:
590/8 = 73.75 ≈ 74

Evaluate the following expression. log4 256
A. 64
B. 16 C. 4 D. 8
Answers
The simplified value of the expression [tex]log_4[/tex] 256 is 4.
Thus, option (C) is correct.
To evaluate the expression [tex]log_4[/tex] 256, determine the power to which 4 must be raised to obtain 256.
So, the equation can be set up
[tex]4^x[/tex] = 256.
Now, put the value of x one by one as
[tex]4^2 = 16[/tex]
[tex]4^3 = 64[/tex]
[tex]4^4 = 256[/tex]
Thus, when the number 4 raise to the power 4 it gives 256.
Thus, option (C) is correct.
