kirill [66]

Answer:

If inflation rate is positive, purchasing power of money decreases thus the rate of returns on investment decreases.

Step-by-step explanation:

When the prices of goods and services are averagely increasing we say that inflation is positive.Purchasing power is high when a currency value is able to purchase more goods and services as per unit of money can buy.when inflation is positive, the amounts of goods and services that can be purchased is reduced.

Emery looks out their apartment window to the building across the way. The building isknown to be 42 feet tall. The angle of dep

Amanda [17]

Answer:

$x=44.5ft$

Step-by-step explanation:

From the question we are told that:

Height $h=42ft$

Angle of depression $\theta=27\textdegree$

Angle of Elevation $\alpha=23 \textdegree$

Generally the equation for the vertical distance between Emery's distance x and the bottom of the building is mathematically given by

Since the angle of depression and elevation are given as

27 and 23 respectively

Therefore

Emery's view of the 42 ft building is

$\gamma=23+27$

$\gamma=50 \textdegree$

Therefore Emery's distance x to the base of the building h' is

$h'=\frac{27}{50}*42$

$h'=22.68ft$

Generally the Trigonometric equation for Emery's distance x is mathematically given by

$x=\frac{h'}{tan\theta}$

$x=\frac{22.68}{tan 27}$

$x=44.5ft$

Use Gauss's Law to find the charge contained in the solid hemisphere x2 + y2 + z2 ≤ a2, z ≥ 0, if the electric field is E(x, y,

Anit [1.1K]

Answer:<em><u> $\frac{16}{3}$ π $a^{3}$ . </u></em>

Given:

$x^{2}+y^{2}+z^{2} \leq a^{2}, z \geq 0$

Using Gauss's Law = ∫∫s E ·dS

= ∫∫∫ div E dV,

⇒ Divergence (Gauss') Theorem

= ∫∫∫ (1+1+6) dV

= 8×(volume of the hemisphere, radius "a")

= 8× ( $\frac{1}{2}$ )(4/3)π $a^{3}$

<em><u>= $\frac{16}{3}$ π $a^{3}$ . </u></em>

David found and factored out the GCF of the polynomial 80b4 – 32b2c3 + 48b4c. His work is below.

Vikentia [17]

Answer:

Given Polynomial:

$80b^4-32b^2c^3+48b^4c$

Factors of Coefficient of terms

80 = 5 × 16

32 = 2 × 16

48 = 3 × 16

Common factor of the coefficient of all term is 16.

Each term contain variable. So the Minimum power of b is common from all terms.

Common from all variable part comes b².

So, Common factor of the polynomial = 16b²

⇒ 16b² ( 5b² ) - 16b² ( 2c³ ) + 16b² ( 3b²c )

⇒ 16b² ( 5b² - 2c³ + 3b²c )

Therefore, Statements that are true about David's word are:

The GCF of the coefficients is correct.

The variable c is not common to all terms, so a power of c should not have been factored out.

In step 6, David applied the distributive property

Frank has 3 bags of birdseed. He wants to put the birdseed into 4 bird feeders equally.how much of the the bags will go in each

svp [43]

Hi!

To solve this, we simply divide.

$\frac{3 bags}{4feeders} = 0.75 bags per feeder$

The answer is 0.75

Hope this helps! :)
