Answer-

90° is the least angle measure by which this figure can be rotated so that it maps onto itself

Solution-

As the figure has two axis of symmetry, placing x and y axis such that the origin lies on its centroid.

Angle between x axis and y axis is 90°.

So rotating any degree which is a multiple of 90 i.e 90°, 180°, 270°, 360°...... would yield the original figure.

Therefore, 90° is the least angle measure by which this figure can be rotated so that it maps onto itself.

Answer: $(3, \infty)$

Step-by-step explanation:

q(x) is increasing for $x > 3$ .

p(x) is increasing for $x \geq -2$ .

So, both functions are increasing for $(3, \infty)$ .

Clara has $67 in her piggy bank. She spent x dollars on a dog bowl and now has $57.4 remains.

kolezko [41]

Answer:

B) 57.4+x=67

Step-by-step explanation:

We take the amount in the piggy bank. Then we take the amount spent and add it to the amount she has left. These two amounts should be equal

piggy bank = spent + left

67 = x + 57.40

Sadie is saving for a new car. Below is the total amount of money in her savings account on the last day of each month. Show all

ICE Princess25 [194]

The mean is 10,724.28.

Explanation:

The mean is all of the values divided by the number of values there are.

So what you have to do is add all of the numbers and divide it by the amount of numbers there are.

10,150+10,211+10,424+10,769+10,884+11,155+11,477= 75,070.

Since there are 7 numbers, divide 75,070/7 and you get your mean, which is 10,724.28 rounded.

He unit circle has a radius of 1 unit and is centered at the origin. It is dilated so that it passes through the point (4, 0).

Advocard [28]

We know that

if the dilated circle passes through the point (4, 0)
so
the new radius is the distance from the origin to point (4,0)
d=√[(4-0)²+0²]-----> d=√16------> d=4 units

the new radius is 4 units
original radius is 1 units

[new radius]=[scale]*[original radius]
scale=new radius/original radius-----> scale=4/1-----> 4

the answer is
the scale factor of dilation is 4
