Can someone tell me if my answer to this problem is correct, please? And if it isn't how do you solve it?

Answer:

Height of tree= 13.8m

Step-by-step explanation:

When finding the value of a in your working, I suggest to leave the answer to 5 significant figures so that your final answer is more accurate. The value of a should be 26.048m to 5 s.f.

Then multiplying 26.048 with sin 32° would give you 13.8m too when rounded off to 3 significant figures :)

I have attached my working too.

Solving Exponential and Logarithmic Equations In Exercise, solve for x. 4e2x - 3 - 5 = 0

Deffense [45]

Answer:

Value of x will be 0.1515

Step-by-step explanation:

We have given the equation $4e^{2x}-3-5=0$

We have top fond the value of x using exponent and logarithmic property

So $4e^{2x}-3-5=0$

$4e^{2x}-8=0$

$4e^{2x}=8$

$e^{2x}=2$

Taking log both side

$lne^{2x}=ln2$

$2x=0.3010$

x = 0.1515

I really need to understand this question! Please answer

mars1129 [50]

Answer:

- 3

Step-by-step explanation:

Using the law of logarithms

$log_{b}$ x = n ⇔ x = $b^{n}$

let $log_{b}$ ( $\frac{1}{b^3}$ ) = n

$log_{b}$ ( $b^{-3}$ ) = n, then

$b^{-3}$ = $b^{n}$

Since bases are the same on both sides then equate the exponents

⇒ n = - 3 → (4)
