★ Logarithmic Reductions ★

$3 + 4 {e}^{x + 1} = 11 \\ 4 {e}^{x + 1} = 11 - 3 \\ 4 {e}^{x + 1} = 8 \\ {e}^{x + 1} = 2 \\ applying \: log_{e} \: to \: both \: the \: sides \\x + 1 = ln2 \\ x = ln2 \: - 1$

Prove that

Dovator [93]

Answer:

see explanation

Step-by-step explanation:

Using the trigonometric identities

secx = $\frac{1}{cosx}$ , cosecx = $\frac{1}{sinx}$

cotx = $\frac{cosx}{sinx}$ , tanx = $\frac{sinx}{cosx}$

Consider the left side

secA cosecA - cotA

= $\frac{1}{cosA}$ × $\frac{1}{sinA}$ - $\frac{cosA}{sinA}$

= $\frac{1}{cosAsinA}$ - $\frac{cosA}{sinA}$

= $\frac{1-cos^2A}{cosAsinA}$

= $\frac{sin^2A}{cosAsinA}$ ( cancel sinA on numerator/ denominator )

= $\frac{sinA}{cosA}$

= tanA = right side ⇒ proven

An ostrich egg weighs 64 ounces is the weight of the ostrich egg greater than 5 pounds?

IgorLugansk [536]

Answer:

An ostrich egg is 4 pounds, therefore, an ostrich egg is not greater than 5 pounds.

Step-by-step explanation:

Convert the ounces to pound.

1 pound = 16 ounces

Next, divide.

64 ÷ 16 = 4.

4 < 5

So, an ostrich isn't greater than 5 pounds

Have a wonderful day!

Which of the following provides an object with rotational symmetry?

Nookie1986 [14]

Answer: Choice C) Star shaped symbol

We can rotate the star symbol 90 degrees to have it line up with its original image. The before and after images would be identical after doing such a rotation. So this figure has rotational symmetry.

The other figures would change if we rotated them some angle x such that $0 < x < 360$ , so they do not have rotational symmetry.
