Answer:

1) b=-1.6 2) g=3 3) x=0.8 4) w=4.9 5) p=-16.2 6) y=9.2

Step-by-step explanation:

Use inverese operations to isolate variables ex. x+4=2

x times 2 = 6 -4

/2 x=-2

x=3

Answer:

$\frac{3+i}{-2i}$ = -0.5 + 1.5i

Step-by-step explanation:

Given 3+i divided by -2i ⇒ $\frac{3+i}{-2i}$

By multiplying the numerator and the denominator by the conjugate of (-2i) which will be equal (2i)

So, $\frac{3+i}{-2i}$ = $\frac{3+i}{-2i} *\frac{2i}{2i} = \frac{i(3+i)}{-2i^2} = \frac{i^2+3i}{-2i^2}$

We should know that: i = √(-1) ⇒ i² = -1

∴ $\frac{i^2+3i}{-2i^2} = \frac{-1+3i}{-2*-1} = \frac{-1+3i}{2} = -0.5 + 1.5i$

∴ $\frac{3+i}{-2i}$ = -0.5 + 1.5i

A study of the annual population of gray squirrels in a Texas state park shows the population, S(t), can be represented by the f

Anastasy [175]

The growth rate of the given function is A) 1

Step-by-step explanation:

Step 1; To calculate the rate we need to see the difference between values at different periods of time. We need to calculate the population at different times.

For t = 1 years, S(t) = 273(1.073)t = 273 × 1.073 × 1 = 292.929,

For t = 2 years, S(t) = 273(1.073)t = 273 × 1.073 × 2 = 585.858,

For t = 2 years, S(t) = 273(1.073)t = 273 × 1.073 × 1 = 878.787.

Step 2; To calculate the growth rate, we divide the difference in the values of the present year and the past year by the value in the past year.

Growth rate between t = 1 and t = 2, Growth rate = S(t=2) - S(t=1) / S(t=1)

= 585.858 - 292.929 / 292.929 = 1.

Growth rate between t = 2 and t = 3, Growth rate = S(t=3) - S(t=2) / S(t=2)

= 878.787 - 585.858 / 585.858 = 1.

So the growth rate is A) 1.

Answer:

x = 17

Step-by-step explanation:

The two angles form a right angle ( indicated by the square )

Right angles have a measure of 90°

Thus, x + 73 = 90

90 - 73 = 17

Hence, x = 17

Evaluate each expression for g = -7 and h = 3 and match it to its value.

Liula [17]

G=-7, h=3 so

1. -4 g+h = -4*(-7)+3 = 312. 2 g-h = 2*(-7) -3 = -17
3. 46 h-g = 46*3-(-7) = 145
4. -10 gh = -10*(-7)*3 = 210
5. -21 g+h^2 = -21*(-7)+3^2 = 159
6. 10 g^2 -h = 10*(-7)^2 - 3 = 487
