Find the missing side lengths. Leave your answers as radicals in simplest form.
anzhelika [568]

Answer:

x=  3sqrt2 y=3

Step-by-step explanation:

The triangle is isosceles triangle, which means 2 sides are congruent. Therefore, y =3

using the pythagorean theorem,

3^2+3^2=x^2

9+9=x^2

18=x^2

x=18 sqrt

3sqrt2

For the given table of values for a polynomial function, where must the zeros of the function lie?
Ymorist [56]

Answer:

(B). between 2.5 and 3.0 and between 4.0 and 4.5.

Step-by-step explanation:

According to the Question,

  • If the value of the function is 0 at x=c, then c is a root or zero of the function. It means the graph of function intersects the x-axis at its zeroes.

From the given table it is clear that the value of function are

 x   |  f(x)  |   Sign

2.0 |  2.8  | Positive  

2.5 |  1.1    | Positive

3.0 | –0.8 | Negative

3.5 | –1.2  | Negative

4.0 | –0.3 | Negative

4.5 |  0.7  | Positive

  • The sign of values of function changes in interval 2.5-3.0 and 4.0-4.5. It means the graph of function must intersect the x-axis in intervals 2.5-3.0 and 4.0-4.5. So, the zeros of the function lie between 2.5 and 3.0 and between 4.0 and 4.5.

Therefore, the correct option is B.

36% of the beans in Pythagoras's soup are lentils, and 33 1/3 of those lentils are green. If Pythagoras removes all the green le
bonufazy [111]

Answer:

Value of x is 88

Step-by-step explanation:

We have,

Percentage of lentils in the soup = 36% = 0.36

Fraction of the lentils which are green = 33\frac{1}{3}

Thus, the amount of green beans in the soup are = 0.36\times 33\frac{1}{3} = 0.36\times \frac{100}{3} = 0.36 × 33.3 = 11.99 ≅ 12.

So, the percentage of the green beans = 12%

The percentage of the original beans in the soup = (100-12)% = 88%

Hence, the value of x is 88.

If you take 50 g of an unknown metal and it takes 1112.5 J of energy to change the temperature
____ [38]

Answer:

0.89 J/g/°C

Step-by-step explanation:

The Heat gained by an object is given in terms of specific heat capacity as:

H = mc(T2 - T1)

where m = mass of the object

c = specific heat capacity

T2 = final temperature

T1 = initial temperature

50 g of an unknown metal takes 1112.5 J of energy to change its temperature  from 20°C to 45°C.

This implies that:

1112.5 = 50 * c * (45 - 20)

1112.5 = 50 * c * 25

1112.5 = 1250 * c

=> c = 1112.5 / 1250

c = 0.89 J/g/°C

The specific heat capacity of the metal is 0.89 J/g/°C
