Answer:
1. 0.20 m, 200 mm
2. 152 cm, 1520 mm
Step-by-step explanation:
You may be familiar with a place-value chart that names the digits of a number based on their relationship to the decimal point. It might look like ...
(units) . (tenths) (hundredths) (thousandths)
So a number like 0.2 units can be rewritten in terms of hundredths or thousandths like this:
0.200 units = 20.0 hundredths = 200. thousandths
The name that's attached depends on where you put the decimal point.
___
When the units are meters, the corresponding names are ...
(meters) . (decimeters) (centimeters) (millimeters)
1. That is 0.200 meters = 20.0 centimeters = 200. millimeters.
2. 1.520 meters = 152.0 centimeters = 1520. millimeters.
Answer:
Here we have:
IxI < 7
This also can be written as:
-7 < x < 7
and:
IyI < 2.
As above, we can write this as:
-2 < y < 2.
Then the graph of this region will be a rectangular area, where the perimeter is a dashed line (because here we use the strictly smaller or strictly larger symbols)
Such that the vertical component goes from -2 to 2, and the horizontal component goes from -7 to 7.
The area would be the area inside that rectangle, where i did not shade it so it is easier to read.
To sketch and shade the region defined by the inequalities |x| < 7 and |y| < 2, identify the boundaries and sketch the rectangle, shading the region within it.
To sketch and shade the region defined by the inequalities |x| < 7 and |y| < 2, we first identify the boundaries of the region. The inequalities |x| < 7 and |y| < 2 represent lines parallel to the x-axis and y-axis, respectively. The region is bounded by these lines and lies within the rectangle with vertices (-7, -2), (-7, 2), (7, -2), and (7, 2). We sketch the rectangle and shade the region within it.

f(x)=-2x^2-7x+6
Find f(−3)
Answer:
f(-3) = 9
Step-by-step explanation:
Step 1: Define
f(x) = -2x² - 7x + 6
f(-3) = x = -3
Step 2: Substitute and evaluate
f(-3) = -2(-3)² - 7(-3) + 6
f(-3) = -2(9) + 21 + 6
f(-3) = -18 + 21 + 6
f(-3) = 3 + 6
f(-3) = 9
Substituting x = -3 into the function f(x) = -2x^2 - 7x + 6, we get f(-3) = -33. Therefore, the value of the function at x = -3 is -33.
To evaluate the function f(x)=−2x ^2 −7x+6 at x=−3, substitute −3 for x in the function: f(−3)=−2{(−3) }^2 −7(−3)+6
Now, calculate each part of the expression:
(−3) ^2 is 9 because the square of −3 is 9.
−2 times 9 is −18 because −2⋅9 =−18.
−7 times −3 is 21 because −7⋅−3=21.
Now, plug these values back into the expression:
f(−3)=−18−21+6
Finally, add and subtract:
f(−3)=(−18−21)+6=−39+6=−33
So, f(−3)=−33.
The value of the function
f(x)=−2x^ 2 −7x+6 at x=−3 is −33.

g(x)=5x^2+4x−5
Let x = -5
g(x)=5 ( -5)^2+4(-5)−5
= 5*25 - 20 -5
=125 - 25
