EASY I AM JUST DUMB!! WILL GIVE BRANLIEST!!! HELP ASAP!!!! What is the value of x in the proportion r/h=h/x?

Keith_Richards [23]

<h3>Answer: D) s</h3>

There are 3 triangles in this diagram. Focus on the smallest triangle that is on the left side. This has a short leg of r and a long leg of h. Now move to the medium sized triangle on the right. It has a short leg of h and a long leg of s

we have these pairings

short legs = {r and h}

long legs = {h and s}

since we go from r to h, then h to s, we can say r/h = h/s

Construct the truth table for:

nordsb [41]

You should know that

p ⇒ q ≡ ¬p ∨ q

so that

p ⇒ (q ∧ r) ≡ ¬p ∨ (q ∧ r)

Then making the truth table is simple:

$\begin{array}{cccccc} p & q & r & \neg p & q \land r & p \implies (q\land r) \\ T & T & T & F & T & T \\ T & T & F & F & F & F \\ T & F & T & F & F & F \\ T & F & F & F & F & F \\ F & T & T & T & T & T \\ F & T & F & T & F & T \\ F & F & T & T & F & T \\ F & F & F & T & F & T \end{array}$

What is the Turing point of f(x)=x^2-2x+8

netineya [11]

Method1:parabola
y = x^2 - 2x + 8
y-7 = (x-1)^2 ; parabola
turning point is (1,7)

method2:diff
y = x^2 - 2x + 8
y' = 2x -2 = 0 ==> x = 1,
y=7

Помогите, пожалуйста

Cerrena [4.2K]

6 - 2х² = 6 - 2(-8)² = 6 - 2(64) = 6 - 128 = -122

$\displaystyle\tt a^{11}\cdot a^{14}=a^{11+14}=a^{25}\\\\a^{18}:a^{14}=a^{18-14}=a^4\\\\(a^5)^4=a^{5\cdot4}=a^{20}\\\\(5x)^4=5^4\cdot x^4=625x^4\\\\\bigg(\frac{a}{3}\bigg)^6=\frac{a^6}{3^6}=\frac{a^6}{729}$

$\displaystyle\tt \frac{14^{16}\cdot14^{6}}{14^{21}}=14^{16+6-21}=14^1=14\\\\\\ \frac{7^{8}\cdot7^{5}}{7^{11}}=7^{8+5-11}=7^2=49\\\\\\ (12^2-11^2)^2+(6^5+2^9)^0=(144-121)^2+1=23^2+1=529+1=530$

$\displaystyle\tt 3^{8x}=81\\\\3^{8x}=3^4\\\\8x=4\\\\x=\frac{4}{8}=\frac{1}{2}=0.5$

$\displaystyle\tt \frac{64^{6}}{4^{4}\cdot4^{16}}=\frac{(4^3)^{6}}{4^{4+16}}=\frac{4^{3\cdot6}}{4^{20}}=\frac{4^{18}}{4^{20}}=\frac{1}{4^{2}}=\frac{1}{16}$

Please help! Will mark brainiest! Write an equation to mark each graph. (absolute value equation.)

asambeis [7]

Answer:

$y=-|x+1|+1$

Step-by-step explanation:

The h and k are the points of the vertex. The h is the one inside the absolute value bars. The k is on the outside. The h has to be the opposite sign from what is on the graph. For example, if the number on the the graph is -1, the number in the <em>equation</em> will have to be a positive 1. The number on the outside stays the same. If the number on the the graph is +1, the number in the <em>equation</em> will also be a positive 1.
