For these questions you’re distributing.

When multiplying exponents it’s quite simple

(x)(x)= x^2
(x^3)(x^3)= x^6

Raising a function with an exponent with another exponent
(x^4)^4 is x^16

So when two functions to a power are multiplied the exponents add. Then a function with an exponent is raised to another exponent, the exponents multiply.

b. 15h^2-10h
c. 12p^4-15pm
d. 12h^3+8h^2g
e. h^4+7h

How do you find the measures of angles G,E and F? Help pleez
JulsSmile [24]

m∠HDG = 28°, m∠EFG = 50°, m∠DEG = 67°, m∠DGE = 65°

Solution:

Triangle sum property:

Sum of the angles of the triangle = 180°

In ΔDHG,

m∠HDG + 120° + 32° = 180°

m∠HDG + 152° = 180°

m∠HDG = 180° – 152°

m∠HDG = 28°

In ΔGEF,

m∠EFG + 17° + 113° = 180°

m∠EFG + 130° = 180°

m∠EFG = 180° – 130°

m∠EFG = 50°

Sum of the adjacent angles in a straight line is 180°

m∠DEG + m∠DEF = 180°

m∠DEG + 113° = 180°

m∠DEG = 180° – 113°

m∠DEG = 67°

In ΔDGE,

m∠DGE + 48° + 67° = 180°

m∠DGE + 115° = 180°

m∠DGE = 180° – 115°

m∠DGE = 65°

Hence m∠HDG = 28°, m∠EFG = 50°, m∠DEG = 67°, m∠DGE = 65°.

There are 27 students in Mr. White's homeroom.
solong [7]

Answer:

0.3935 to 4 places of decimals.

Step-by-step explanation:

Use  binomial probability tables  or an online probability calculator.

Here Prob(a singles success) = 0.08333  ( that is 1/12)

Number of successes = 3 and number of trials = 27.

You want the probability of the variable X being >= x.

Step-by-step explanation:

A)

P(t) = Po(2)x^\frac{t}{d} \\=5(2)^\frac{7}{4} \\=16.817mg

B)

320=5(2)^\frac{t}{4}\\ 64=2^\frac{t}{4}\\2^6=2^\frac{t}{4}\\6=\frac{t}{4}\\(4)6=t \\t=24 days
