Write and solve an equation to find the value of x and the missing angle measures

Mathematics
1 answer:
Romashka [77]3 years ago
3 0

Answer:

x=8

the top angle=120

the bottom angle=120

Step-by-step explanation:

angle rules say that those angles will be equal

therefore right the quation 14x+8=16x-8

and solve for x

The sun produces 3.9 ⋅ 10 to the 33th power ergs of radiant energy per second. How many ergs of radiant energy does the sun prod
arlik [135]
So the sun produces 3.9x10³³/ second

Using this ratio (3.9x10³³/ second) we can use the porpotions to calculate time taken (T) to produce 1.55x10⁷.

\frac{3.9(10^3) ergs}{1 second} =  \frac{1.55(10^7)ergs}{T}

Then isolate T and find the time

\frac{T3.9(10^3)ergs}{1 second} = {1.55(10^7)ergs
T3.9(10^3)ergs = ({1.55(10^7)ergs)seconds
T =  \frac{(1.55(10^7)ergs)seconds}{3.9(10^3)ergs}
T =  \frac{(1.55(10^7)seconds}{3.9(10^3)}
T = \frac{1.55}{3.9}(10^4)seconds
T = 0.397(10^4)seconds
T = 3.97(10^-^1)(10^4)seconds
T = 3.97(10^3)seconds

Thus it took 3.97x10³ seconds for 1.55x10⁷. of ergs to be produced

The graph of the continuous function g, the derivative of the function f, is shown above. The function g is piecewise linear for
4vir4ik [10]
A) g=f' is continuous, so f is also continuous. This means if we were to integrate g, the same constant of integration would apply across its entire domain. Over 0, we have g(x)=2x. This means that


f_{0


For f to be continuous, we need the limit as x\to1^- to match f(1)=3. This means we must have


\displaystyle\lim_{x\to1}x^2+C=1+C=3\implies C=2


Now, over x, we have g(x)=-3, so f_{x, which means f(-5)=17.


b) Integrating over [1, 3] is easy; it's just the area of a 2x2 square. So,


\displaystyle\int_1^6g(x)=4+\int_3^62(x-4)^2\,\mathrm dx=4+6=10


c) f is increasing when f'=g>0, and concave upward when f''=g'>0, i.e. when g is also increasing.

We have g>0 over the intervals 0 and x>4. We can additionally see that g'>0 only on 0 and x>4.


d) Inflection points occur when f''=g'=0, and at such a point, to either side the sign of the second derivative f''=g' changes. We see this happening at x=4, for which g'=0, and to the left of x=4 we have g decreasing, then increasing along the other side.


We also have g'=0 along the interval -1, but even if we were to allow an entire interval as a "site of inflection", we can see that g'>0 to either side, so concavity would not change.

frosja888 [35]

Answer:

$204.4

Step-by-step explanation:

The four chairs bought in June cost $35 each, all together $140. Then they bought 2 more chairs on sale for 8% off of $35 each or 92% of $35 which is $32.2 each, all together $64.4. Both buy's together would then equal $204.4

Write a polynomial to represent the value of d dimes and n nickels.
nadya68 [22]
Answer: 0.10d + 0.05n
Note: this value expression is in dollars (not cents)
If you want the expression in cents instead of dollars, then it would be 10d+5n

--------------------------------------------------------------------------------

The value of just the dimes only is 0.10d dollars
The value of just the nickels only is 0.05n dollars
Combined the total value is 0.10d+0.05n dollars
