On simplifying (3+√3 )(5- √2), the value is
A. 112
B. 18
C. 6
D. 21
no spam and please explain ur answer .
Answer:
18
Step-by-step explanation:
( 3 + √3 ) ( 5 - √2 )
= 3 ( 5 - √2 ) + √3 ( 5 - √2 )
= 15 - 3√2 + 5√3 - √6
√2 = 1.41 ( approximately )
3√2
= 3 x 1.41
= 4.23
√6 = 2.44
√3 = 1.73
5√3
= 5 x 1.73
= 8.65
15 - 3√2 + 5√3 - √6
= 15 - 4.23 + 8.63 - 2.44
= 15 + 8.63 - 4.23 - 2.44
= 15 + 8.63 - 6.67
= 15 + 1.93
= 16.93
Rounding of 16.93 = 17
17 is near to 18.
So, 18 can be the answer.
The ratio of the volume of sphere A to the volume of sphere B is [tex]\frac{125}{64}[/tex]
What is the ratio of the radius of sphere A to the radius of sphere B?
Answer:
Step-by-step explanation:
let radius of shere A=R
radius of sphere B=r
[tex]\frac{volume~of~sphere ~A}{volume~of~sphere~B} =\frac{\frac{4}{3} \pi R^3}{\frac{4}{3} r^3} =\frac{125}{64} \\(\frac{R}{r} )^3=(\frac{5}{4} )^3\\\frac{R}{r} =\frac{5}{4}[/tex]

Which type of function is shown in the table below?
Answer:
Linear
Step-by-step explanation:
As x increases by 1, f(x) decreases at a constant rate of -5.
Since the rate is constant, the function must be linear.
Write the equation of a linear function and define one point that lies on this function. Write the equation of your function translated 4 units to the left and 5 units down. What are the coordinates of your new point?

A new drug cures 65% of the patients who take it. If it is given to 14 patients, what is the probability that at least 12 will be cured?
Answer:
[tex]P(X \geq 13) = 0.021[/tex]
Step-by-step explanation:
From the question we are told that:
Probability of curing patients P(x)=0.65
Sample size n=14
Generally the Binomial equation is mathematically given by
[tex]P(X) =\frac{(n!)}{X!(n-X)!))} *p^X*(1-p)^(n-X)[/tex]
Generally the equation for Equation for at least 12 cured is mathematically given by
[tex]P(X \geq 13) = P(X = 13)+P(X = 14)[/tex]
For [tex]P(X = 13)[/tex]
[tex]P(X = 13) = (14!/(13!(14-13)!))*0.65^13*(1-0.65)^(14-13) \\\\P(X = 13)= 0.018116[/tex]
For [tex]P(X = 14)[/tex]
[tex]P(X = 14) = (14!/(14!(14-14)!))*0.65^14*(1-0.65)^(14-14) \\\\P(X = 14)= 0.00240318[/tex]
Therefore
[tex]P(X \geq 13) =P(X = 13)+P(X = 14)[/tex]
[tex]P(X \geq 13) = 0.018116+0.00240318[/tex]
[tex]P(X \geq 13) = 0.02051918[/tex]
[tex]P(X \geq 13) = 0.021[/tex]
please help me complete these -5a^2+ 5a = _______(a – 1) and 18x^2 + 2x³ = _______(9 + x) I need to complete the blanks
Answer:
Step-by-step explanation:
-5a^2+ 5a factors as follows: -5(a - 1) (so -5 goes into the blank space).
18x^2 + 2x³ factors as follows: 2x^2(x + 9) (so 2x^2 goes into the blank space)
A student has a total of 233 points on three tests. The scores on the first and second tests are the same. The third score exceeds the second (or the first) by 14. Find the three scores.
Answer:
Let the scores on the first two test be x
Let score for third test be 14 exceeds second( or first) = x + 14
Total = 233
x + x + (x + 14) = 233
3x + 14 = 233
3x = 219
x = 73
Score of the third test = x + 14 = 73 + 14 = 87
Therefore, the scores are 73, 73, 87

I need this before the 24th!
100 points!
Answer:
The interval is [4,7]
Step-by-step explanation:
The rate of change is given by
f(x2) - f(x1)
-------------------
x2 -x1
We want the rate of change to be 56
f(x2) - f(x1)
------------------- = 56
x2 -x1
We also know that the x2 is 7 so f(x2) = 192
192 - f(x1)
------------------- = 56
7 -x1
192 - f(x1) = 56( 7 -x1)
192 - f(x1) = 392 -56x1
Now we need to pick points from the table and see where it is true
(6,96)
192 - 96 = 392 -56*6
96=56 False
( 5,28)
192 - 28 = 392 -56*5
164=112 False
(4,24)
192 - 24 = 392 -56*4
168=168 True
The interval is [4,7]
