Step-by-step explanation:
The applicable rules of angles and arcs are ...
the whole is the sum of the partsarcs of a circle total 360°an inscribed angle intercepts an arc of twice its measure__
10) Angles C and L intercept the same arc (DE) so will have the same measure.
15x = 16x -4
4 = x . . . . . . . . add 4-15x
arc DE = 2(15x) = 30(4) = 120 . . . degrees
__
11) Arc VW is twice the measure of angle X, so ...
9x +8 = 2(5x)
8 = x . . . . . . . . . subtract 9x
∠VXW = 5x = 5(8) = 40 . . . degrees
__
12) Arc EFG is twice the measure of angle W, so ...
70° +FG = 2(88°)
FG = 106° . . . . . . . . . subtract 70°
Arc FGW is twice the measure of angle E, so ...
106° +GW = 2(80°)
GW = 54° . . . . . . . . . . subtract 106°
__
13) Arc ST is twice the measure of angle R. The sum of arcs is 360°.
RS +ST +TR = 360°
119° +2(70°) +TR = 360°
TR = 101° . . . . . . . . subtract 259°

How can limit be used in real life
Answers
Answer:
Engineers use limits in real life.
Step-by-step explanation:
Limits are also used as real-life approximations to calculating derivataves. So to make calculations, engineers will approximate a function using small differences in the function and then try and calculate the derivative of the function by having smaller and smaller spacing in the function sample intervals.

Johnny was buying pizza rolls. One sausage pizza roll cost 1.54 and he also bought pepperoni flavored rolls. If he buys 6 sausage rolls and 10 pepperoni rolls and he spends $22.54 in total. How much does a pepperoni roll cost?
Answers
Answer:
$1.33
Step-by-step explanation:
multiply 6 by 1.54 to see how much he spent on sausage rolls
subtract that from the total ($22.54)
divide by 10 to see how much each pepperoni roll costs
Answer:
$1.33
Step-by-step explanation:
1.54x6=9.24
22.54-9.24=13.30
13.30/10=1.33

Answers
Answer:The zeros are 6, -5, 9
Step-by-step explanation:
The zeros of the polynomial function are x = 6, x = -5, and x = 9. The correct option is A.
What are polynomials?In mathematics, a polynomial is an expression that solely uses the operations of multiplication, addition, subtraction, and non-negative integer exponentiation of variables. It is made up of coefficients and indeterminates.
The zeros of the polynomial function are the values of x that make f(x) equal to zero.
The polynomial f(x) is written in factored form as:
f(x) = (x - 6)(x + 5)(x - 9)
The zeros of the polynomial are the values of x that make any of the factors equal to zero. Therefore, the zeros are:
x - 6 = 0, which gives x = 6
x + 5 = 0, which gives x = -5
x - 9 = 0, which gives x = 9
Thus, the zeros of the polynomial function are x = 6, x = -5, and x = 9.

D. one-third
Answers
Answer:
8/9
Step-by-step explanation:
let the number rolled be two dies
When two dice are rolled, the total outcome will be 6² = 36
The pair that gives a sum of 5 are (1,4), (4,1) ,(2, 3), (3, 2). These gives 4 outcomes.
The pair that gives the sum greater than 5 = 36 - 4 = 32
Pr(sum is greater than 5) = Expected/Total outcome
Pr(sum is greater than 5) = 32/36
Pr(sum is greater than 5) = 8/9

Since the calculated value of z= -1.421 does not lie in the critical region z >
- 1.96 the null hypothesis is accepted and it is concluded that the treatments result in the same effect.
Step-by-step explanation:
1) Let the null and alternate hypothesis be
H0: μa − μb = 0 the treatments result in the same effect
against the claim
Ha: μa − μb ≠ 0 the treatments do not result in the same effect
2) The significance level is set at 0.05
3) The critical region is z = ± 1.96
4) The test statistic
Z= x1`-x2`/ sqrt [( s1²/n1+ s2²/n2)]
Here
x1`= 17 s1= 4 n1= 13
x2`= 19 s2= 3 n2= 12
5) Calculations
Z= x1`-x2`/ sqrt [( s1²/n1+ s2²/n2)]
z= 17-19/sqrt [( 16/13+ 9/12)]
z= -2/1.40739
z= -1.421
6) Conclusion
Since the calculated value of z= -1.421 does not lie in the critical region z >
- 1.96 the null hypothesis is accepted and it is concluded that the treatments result in the same effect.
