Solve the following quadratic by<br> completing the square.<br> y = x2 + 10x + 10

IgorC [24]

Answer:

<h2> x = -5 - √15 or x = -5 + √15</h2>

Step-by-step explanation:

$y = x^2+10x+10\\\\y=x^2+10x+25-25+10\\\\y=(x+5)^2-15\\\\y=0\quad\iff\quad (x+5)^2-15=0\\\\(x+5)^2=15\\\\x+5=\pm\sqrt{15}\\\\x=-5-\sqrt{15}\quad or\quad x= -5+\sqrt{15}$

A clothing manufacturer produces 120 garments per hour, of which 5 are damaged. How many garments without damage would the manuf

sp2606 [1]

Answer:

<h2>Step-by-step explanation:</h2>

First we have to found all the clothes that the manufacturer produces in 8 hours,

As given 120 clothes = produce in 1 hour

X clothes = produce in 8 hour

By cross multiplication, we get

X= 120*8

X= 960 total clothes produced in 8 hours

As also given that in each hour 5 clothes damaged ,so we can write as

5 clothes = damaged in 1 hour

Y clothes = Damaged in 8 hour

By cross multiplication we get

Y= 40 clothes damaged in 8 hour

So the total clothes that manufacturer produce with out damage clothe will be ,

Total normal clothes = X-Y = 960 - 40 = 920 clothes

(50 POINTS) Math Inverse Functions please help

Afina-wow [57]

Answer:

See below.

Step-by-step explanation:

An inverse function has the x and y coordinates switched. For example, if a function has point (1, 3), then the inverse function has point (3, 1).

Let's find the ordered pairs of the inverse function. We take all the ordered pairs of the original function:

(1, 3), (7, 4), (8, 6), (9, y)

Now we switch x and y in each ordered pair to come up with the inverse function.

The inverse function has these ordered pairs:

(3, 1), (4, 7), (6, 8), (y, 9)

For a relation to be a function, a value used as an x-coordinate can appear only once.

The last ordered pair is (y, 9). For the inverse relation to be a function, y cannot be 3, 4, or 6.

In October sally drove 560 miles in her car.

torisob [31]

The cost is £79.76. Since the car covers 560 miles and 34.5 miles is travelled by one gallon. So, dividing 560 by 34.5 we get 16.23. Since 1 gallon is 4.55 litres, 16.23 gallons is 73.8465. Now the cost of petrol is £1.08 per litre. So, multiplying 73.8465 by £1.08 we have £79.76

Are 3:5and 1:2 equivalent

german

Answer:

No. They are not equivalent.

Step-by-step explanation:

$\frac{3}{5} \neq \frac{1}{2}$

=> $\frac{6}{10} \neq \frac{5}{10}$

Therefore, 3/5 and 1/2 are not equivalent.
