Step-by-step explanation:

carly had nothing, amount of money = £0

amy gave her £7 and brad gave her £5,

carly now has £5 and £7

amount of money of carly= £7 + £5

= £12

you are told that they all have the same amount of money and you know that carly has £12. so:

amy has £12, brad has £12 too.

If amy has £ 12 now after giving away £7, then: let x be the initial amount of money amy had,

x - 7 = 12

x = 12 + 7

x = 19

thus, amy had £19.

Which transfromations tranforms the graph of f(x)=x^2 to the graph of g(x)=(x+4)^2?

wariber [46]

Greetings from Brasil...

In function F(X) = X², if we replace X with X + 4 we will have exactly function G(X) = (X + 4)²

So, just replace X for X + 4..... This will be responsible for translating 4 units to the left, because:

F(X) = X²

F(X + 4) = (X + 4)²

F(X + 4) ⇔ F(X + k) see below

We know that the translations are established as follows:

→ Horizontal

F(X + k) ⇒ k units to the left

F(X - k) ⇒ k units to the right

Allushta [10]

Answer: 50.85 meters

Step-by-step explanation:

cos 29 = $\frac{55}{h}$

55 cos 29 = h

48.10 = h

Pole = h + 2.75

= 48.10 + 2.75

= 50.85

Answer:

(1) False

(2) False

(3). False

(4) False

Step-by-step explanation:

According to the problem, calculation of the given data are as follows,

(1). Given, 149 + 769 = 819

By calculating 149 + 769 = 918

Hence, False

(2). Given, 556 + 336 = 826

By calculating 556 + 336 = 892

Hence, False

(3). Given, 458 - 248 = 238

By calculating 458 - 248 = 210

Hence, False

(4). Given, 658 - 228 = 438

By calculating 658 - 228 = 430

Hence, False

How find derivative of function: y=arcsin(2x+1) ...?

Setler [38]

$( \arcsin{x})'= \frac{1}{ \sqrt{1-x^2} } 
\\
\\ (\arcsin{(2x+1)})'= \frac{1}{ \sqrt{1-(2x+1)^2} } (2x+1)'= \frac{2}{ \sqrt{1-(4x^2+4x+1)} } =
\\
\\= \frac{2}{ \sqrt{-4x^2-4x} } =\frac{2}{ \sqrt{4x(-x-1} )} =\frac{2}{ 2\sqrt{x(-x-1} )} =\frac{1}{ \sqrt{x(-x-1} )}$
