Andrews [41]2 years ago
6 0

Answer:

Step-by-step


Let us assume that the third leg is X. So, X^2 + 2^2 = 5^2.X^2 = 25 - 4.X^2 = 21.X = root 21.


a right triangle, hypotenuse=5 cm, one leg=2 cm, the other leg=xApplying the Pythagorean theorem:5^2=2^2+x^2, 25=4+x^2,x^2=25–4=21, x=sqrt(21), x=4,58 cmThe measurement of the other leg is 4,58 cm

Identify a pattern in the given list of numbers. Then use this pattern to find the next number.
Rom4ik [11]

Answer:

The given sequence is geometric sequence

In the given pattern we have next number is a_5=\frac{1}{4}

Step-by-step explanation:

Given numbers are 64,-16,4,-1

To identify the pattern of the given numbers :

Let a_1=64, a_2=-16 ,a_3=4  and a_4=-1

To find the next number that is a_5

common ratio r=\frac{a_2}{a_1}

=\frac{-16}{64}

r=-\frac{1}{4}

r=\frac{a_3}{a_2}

=\frac{4}{-16}

r=-\frac{1}{4}

Therefore the common ration is r=-\frac{1}{4}

Therefore the given sequence is geometric sequence

The nth term of the geometric sequence is a_n=a_1r^{n-1}

Now find the 5th term so put n=5 , a_1=64andr=\frac{-1}{4} we have

a_5=64(\frac{-1}{4})^{5-1}

=64(\frac{-1}{4})^{4}

=64(\frac{1}{4})^{4}

=64(\frac{1}{4}\times \frac{1}{4}\times \frac{1}{4}\times \frac{1}{4})

=\frac{1}{4}

Therefore a_5=\frac{1}{4}

Equivalent expression of 10+(x divided 16)
Ivahew [28]

Answer:

x/16 + 10

Step-by-step explanation:

10+(x÷16)

To add or subtract expressions, expand them to make their denominators the same. Multiply 10 times 16/16.

10 x 16 / 16 + x/16

Since 10 x 16 / 16 and x/16 have the same denominator, add them by adding their numerators.

10 x 16 + x / 16

Do the multiplications in 10×16+x.

160 + x / 16 = x/16 + 10

The domain of the function f(x) = 3x3 is {2, 5}. What is the function’s range?
Sholpan [36]
The domain is {2,5} which the set containing the numbers 2 and 5. I'm assuming that the function is f(x) = 3x3<span>. So...

</span>when x = 2, f(x) = 3*23<span> = 3*8 = 24.
</span>when x = 5, f(x) = 3*53<span> = 3*125 = 375.

so this means the functions range is {24, 375}

hope this helped you out</span>
