Answer:

Option 1st is correct

(1, -3)

Step-by-step explanation:

The rule of dilation with center (0, 0) and a scale factor k is given by:

(x, y) \rightarrow (kx, ky)

As per the statement:

From the given diagram:

Coordinate of G is: (1, -3)

We have to find image of G for a dilation with center (0, 0) and a scale factor of 1.

Scale factor(k) = 1

Apply the rule on G, to find G'

G(1, -3) \rightarrow (1 \cdot 1, 1 \cdot -3)=G'(1, -3)

Therefore, the image of G for a dilation with center (0, 0) and a scale factor of 1 is, (1, -3)

If angle 1 and angle 2 are complementary angles and if the measures of angle 1 is 8 more than the measure of angle 2 determine t
babunello [35]

Answer:

41° and 49°

Step-by-step explanation:

Given:

Angle 1 and angle 2 are complementary angles.

The measures of angle 1 is 8 more than the measure of angle 2.

Question asked:

Determine the measures of angle 1 and 2.

Solution:

Let ∠1 = x

Then ∠2 = x+8   (given)

As we know that sum of complementary angles are 90° and here given that angle 1 and angle 2 are complementary angles which means,

∠1 + ∠2 = 90°

x+x+8=90°

2x +8=90°

Subtracting both sides by 8,

2x=90°-8

2x = 82°

Dividing both sides by 2,

x=41°

∠1 = x=41°

∠2 = x+8

∠2 = 41+8 = 49°

Therefore, the measures of angle 1 and 2 are 41° and 49°

I need help with these two problems !!
wolverine [178]

Not so sure about the second one, but the first one is pretty simple:

The area of a circle = pi x radius^2

Since you need to find the area of the entire dvd, I'm assuming they mean if the hole in the center wasn't there, so add that to the diameter.

12+1.5 = 13.5

Half of the diameter is the radius, so half of 13.5 = 6.75

Now, multiply pi (3.14) by the radius, but have the radius squared. You'd write the equation like this:

3.14 x 6.75^2 (or on paper, the ^2 would be a small two diagonal from the 5)

Actual answer: 143.06625

You can round that to 143.

Answer:

2x - 5 if x ≤ 2

f(-1) = -7

Step-by-step explanation:

x ≤ 2 = (-1) ≤ 2

x > 2 = (-1) > 2

2x - 5

2(-1) - 5

-2 - 5

-7
