The piecewise function all the way to the left (x + 3) should have an ending point shaded in. [At x = -2] The next function ((x^2) -1) should have both ending points left unshaded. Finally, the logarithm function should have a shaded in starting point [At x = 1] and should have an unshaded ending point at x = 3.

In the whole number 70,819 the place value of the digit 1 is

bulgar [2K]

Step-by-step explanation:

a number is a sequence of digits with every position being multiplied by increasing powers of 10.

and the whole number is then the sum of of these little multiplications.

the first position left of the decimal point is for 10⁰ (1). the second position is 10¹ (10). the third position for 10² (100). and so on.

the given number is therefore just the short version of

7×10⁴ + 0×10³ + 8×10² + 1×10¹ + 9×10⁰

and therefore, the digit 1 in this number has the value 1×10¹ = 10, which is also the place value, 10¹ = 10.

Christian has a cookie recipe that yields four dozen cookies and calls for 2 1/4 cups white sugar and 3/4 cup brown sugar.cif ch

Paha777 [63]

The ingredients given are for 4 dozen cookies; however, Christian only want to make one dozen, meaning he requires only 1/4 the ingredients.

1/4 of 2 1/4 cups of while sugar is found the following way.

First, we write 2 1/4 as an improper fraction

$2\frac{1}{4}=2+\frac{1}{4}=\frac{9}{4}$

1/4 of this is

$\frac{9}{4}\times\frac{1}{4}=\frac{9}{16}$

Hence, Christian requires 9/16 cups of white sugar.

Similarly, the 1/4 of 3/4 cups of brown sugar is

$\frac{1}{4}\times\frac{3}{4}=\frac{3}{16}$

Hence, Chrisitan requires 3/16 cups of brown sugar.

Therefore, the total cups of sugar required is the sum of

$\frac{3}{16}+\frac{9}{16}=\frac{12}{16}=\frac{3}{4}$

3/4 cups of sugar.

circle 1 is centered at 4,3 and has a radius of 5 centimeters circle 2 is centered at 6,-2 and has a radius of 15 centimeters. W

wolverine [178]

We know that
Figures can be proven similar if one, or more, similarity transformations (reflections, translations, rotations, dilations) can be found that map one figure onto another.
In this problem to prove circle 1 and circle 2 are similar, a translation and a scale factor (from a dilation) will be found to map one circle onto another.

we have that
Circle 1 is centered at (4,3) and has a radius of 5 centimeters
 Circle 2 is centered at (6,-2) and has a radius of 15 centimeters

step 1
Move the center of the circle 1 onto the center of the circle 2
the transformation has the following rule
(x,y)--------> (x+2,y-5)
so
(4,3)------> (4+2,3-5)-----> (6,-2)
so
center circle 1 is now equal to center circle 2
The circles are now concentric (they have the same center)

step 2
A dilation is needed to increase the size of circle 1 to coincide with circle 2

scale factor=radius circle 2/radius circle 1-----> 15/5----> 3

radius circle 1 will be=5*scale factor-----> 5*3-----> 15 cm
radius circle 1 is now equal to radius circle 2

A translation, followed by a dilation will map one circle onto the other, thus proving that the circles are similar
