Marta_Voda [28]3 years ago
5 0

Step-by-step explanation:

x^2 - (a+b)x + ab = 0

here, a = 3 and b = 7

hence,

x^2 - (10x) + 21 = 0

lastly , the quadratic equation is

x^2 - 10x + 21 = 0

Answer:

sin = \frac{\sqrt{5} }{3}

Step-by-step explanation:

                                             <u>SOH CAH TOA</u>

Where:

s = sin

c = cos

t = tan

o = opposite

a = adjacent

h = hypotenuse  

cos = 2/3 where 2 is adjacent side and 3 is hypotenuse, now find opposite side using a^2 + b^2 = c^2 //c is hypotenuse side

2^2 + b^2 = 3^2

4 + b^2 = 9

b^2 = 9 - 4

b^2 = 5

b = square root (5) = 5^(1/2) //opposite side

sin = O/H

sin = \frac{\sqrt{5} }{3}

//Hope it helps.

The table shows the results of an experiment in which the spinner shown above was spun 50 times. Find the experimental probabili
torisob [31]

Answer:

P(x < 4) = \frac{9}{50}

Step-by-step explanation:

Given

n(S) = 50

See attachment for distribution

Required

P(x < 4)

This is calculated as:

P(x < 4) = \frac{n(1) + n(2) + n(3)}{n(S)}

Using the data on the frequency distribution table, we have:

P(x < 4) = \frac{4 + 2 + 3}{50}

P(x < 4) = \frac{9}{50}

After years of maintaining a steady population of 32,000, the population of a town begins to grow exponentially. After 1 year an
qwelly [4]

Answer:

y = 32,000(1.08)^x

Step-by-step explanation:

The exponential growth equation is y = a(1 + r)^x, where a is the initial amount, r is rate as a decimal, and x is the time.

In this situation, 32,000 is the initial amount (a) and 0.08 is the rate (r)

If we plug these into the equation, we get the equation y = 32,000(1.08)^x

So, y = 32,000(1.08)^x is the correct answer.
