z + 93 = 180

z = 87

Answer z = 87

Here are the answer for x and y, in case you need them.

x = 2* 93 - 112

x = 186 - 112

x = 74

y = 2 * 80 - x

y = 160 - 74

y = 86

Answer:

$z=87^{\circ}$

Step-by-step explanation:

We have been given image of a circle. We are asked to find the value of z for our given circle.

We can see that our given quadrilateral is a cyclic quadrilateral. We know that opposite angles of a cyclic quadrilateral are supplementary.

We can set an equation using our given information.

$93^{\circ}+z=180^{\circ}$

$93^{\circ}-93^{\circ}+z=180^{\circ}-93^{\circ}$

$z=87^{\circ}$

Therefore, the value of z is 87 degrees.

Rewrite the function by completing the square. f(x) = x2 – 10x + 44 + f(x) = (x+

iVinArrow [24]

Answer:

$f(x)=(x-5)^{2}+19$

Step-by-step explanation:

we have

$f(x)=x^{2}-10x+44$

Group terms that contain the same variable, and move the constant to the opposite side of the equation

$f(x)-44=x^{2}-10x$

Complete the square. Remember to balance the equation by adding the same constants to each side.

$f(x)-44+25=x^{2}-10x+25$

$f(x)-19=x^{2}-10x+25$

Rewrite as perfect squares

$f(x)-19=(x-5)^{2}$

$f(x)=(x-5)^{2}+19$

Step-by-step explanation:

Put numbers in order, 1,3,3,4,5,8,9,12

Divide by 2 because there are 2 numbers

Because 4.5 is in the middle of 4 and 5 that is your median

HI decomposes into its elements according to second-order kinetics. What concentration of HI remains from an initial concentrati

Novosadov [1.4K]

Answer:

Therefore (2.30-0.03747)= 2.2625 M of HI remains from an initial concentration of 2.30 M after 4.5 hours.

Step-by-step explanation:

second order reaction: The rate of reaction proportional to the square of the concentration of reactant.

For second order reaction

$k=\frac{x}{ta(a-x)}$

K is rate constant = 1.6×10⁻³M⁻¹hr⁻¹

a = initial concentration of reactant = 2.30 M

a-x = concentration of reactant after t h

t = time = 4.5 h

Putting the values in the above equation,

$1.6\times 10^{-3}= \frac{x}{4.5 \times 2.30 \times (2.30-x)}$

$\Rightarrow 16.56 \times 10^{-3}\times (2.30-x)= x$

$\Rightarrow 16.56 \times 10^{-3}\times 2.30-16.56 \times 10^{-3}\times x= x$

$\Rightarrow (1+16.56 \times 10^{-3}) x=16.56 \times 10^{-3}\times 2.30$

$\Rightarrow x = 0.03747$

Therefore (2.30-0.03747)= 2.2625 M of HI remains from an initial concentration of 2.30 M after 4.5 hours.
