How do I find the missing side

vekshin1

Answer:

x = 11.8639

Step-by-step explanation:

cos∅ = adjacent / hypotenuse

Since we are dealing with right triangles, we can use trig to help solve for missing values:

cos22° = 11/x

xcos22° = 11

x = 11/cos22°

x = 11.8639

Find the slope of the tangent line to the graph of each equation at x = 1. y = x3

Jet001 [13]

Answer: the answer is 3

Step-by-step explanation: The gradient (or slope) of the tangent to a curve at any particular point is given by the derivative at that point If y = x 3 then d y d x = 3 x 2 When x = 1 ⇒ d y d x = 3 So the slope equals 3

Answer: q³⁰

Explanation:

First just solve the first part using the exponent rules

p²q⁵ becomes 1/p-⁸q-²⁰ then we flip the fraction so the exponents become positive. Now we have p⁸q²⁰.

Before multiplying the other equation, we must simplify. p-⁴q⁵ becomes 1/p⁴q-⁵ and since it's the exponents being raised to a power we simply multiply the inner exponents times the outer exponent which yields 1/p⁸q-¹⁰. We must make q-¹⁰ positive so we will then bring it to the numerator of the fraction which gives us: q¹⁰/p⁸.

Multiply q¹⁰/p⁸ * p⁸q²⁰/1 = p⁸q³⁰/p⁸ divide the p exponents by each other which yields 0 since when u divide exponents you just subtract them so 8 - 8 = 0. Your answer is now q³⁰/1 or just q³⁰

I am thinking of a number. My number is between 20 and 30 My number and 12 have only one common factor. What number could I be t

zhannawk [14.2K]

Answer:

21, 22 and 26

Step-by-step explanation:

To answer this question first we need to know which are the factors of 12:

$12= 2^2(3)$

So, now, we need 3 numbers that are <u>between 20 and 30 and that only have one common factor with 12</u>, in other words, they need to have just a 2 or a 3 in their factorization.

Let's take number 21:

$21= (7)(3)$ , we can see that 21 only has a 3 and a prime so therefore it has only one common factor with 12

Now, let's take the number 22,

$22=11 (2)$ , thus since 22 has a 2 and a prime, it has only one common factor with 12.

Now, let's take the number 26

$26= 13 (2)$ , thus, since 26 has a 2 and a prime, it has only one common factor with 12.

Thus, the three possible answers are 21, 22 and 26
