Answer:

The answer is 0.005.

Step-by-step explanation:

When you divide any number by 10, you move the decimal point over to the left by 1 place.

If, for example, you were instead multiplying by 10, your answer would change to 0.5.

Need help please this question is very confusing i would love some help

Natali [406]

Answer:

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

here (h, k) = (- 3, - 6), thus

y = a(x + 3)² - 6

To find a substitute (0, 0) into the equation

0 = 9a - 6 ⇒ a = $\frac{6}{9}$ = $\frac{2}{3}$

y = $\frac{2}{3}$ (x + 3)² - 6 ← in vertex form

Expand (x + 3)² and distribute by $\frac{2}{3}$

y = $\frac{2}{3}$ (x² + 6x + 9) - 6

= $\frac{2}{3}$ x² + 4x + 6 - 6

= $\frac{2}{3}$ x² + 4x ← in standard form

Minchanka [31]

The temperature at the beginning of the day was 6.2°F

Let x represent the temperature at the beginning of the day.

Since, the temperature of a city doubles during the day, and then decreases by 14.1ºF after the sun goes down, hence:

Temperature at end of day = 2x - 14.1

Also, the temperature at the end of the day is −1.7°F, hence:

2x - 14.1 = -1.7

2x = 12.4

x = 6.2°F

The temperature at the beginning of the day was 6.2°F

Answer:

Point R is at (-40,30), a distance of 60 units from point Q

Step-by-step explanation:

Explanation

we will use below conditions

Type of transformation change to co-ordinate point

vertical translation up 'd' units (x, y) changes to (x, y +d)
vertical translation down 'd' units (x, y) changes to (x, y-d)
horizontal translation left 'c' units (x, y) changes to (x- c, y)

4. horizontal translation right 'c' units (x, y) changes to (x+ c , y)

now Given data is P( 20,-30) and in the graph Q(-40,-30)

Step1:-

Now we have to find 'R' point

Given data the point "R' is vertically above point Q so the point "Q' is moves vertically up with '60' units

now we will use the condition (1)

Q(-40,-30) is vertical translation up '60' units now changes the co-ordinate point is (-40 , -30+60)

The correct translation and The point R( -40 , 30)

Step2:-

Again in the given data "R" is at the same distance from point Q as point P is from point Q.

so given P point is (20 , -30)

now we translation 'P' also

vertically translation up at a distance '60' units and changes the new co-ordinate (20 , -30+60) that is (20,30) [ use above condition is (1)]

and again horizontal translation left '60' now changes (20 - 60 ,30)[ use condition (3)]

There fore the new co-ordinate is R( -40 , 30)

Final answer:-

Point R is at (−40, 30), a distance of 60 units from point Q
