Answer:
w = 1/2
Step-by-step explanation:
One of the ways to solve problems using log is to use these two equations that use the same variables and plug in numbers.
log b (a) = c
b^c = a
By plugging in the numbers we get this:
log 16 (4) = w
16^w = 4
w = 1/2
Answer:
Step-by-step explanation:
Scale factor shows by how much the original model has been multiplied or divided by to get the measurements of the drawing .
In this case the ladybug is 8 mm long but drawing length is 2 cm.
Let’s convert both into the same units
2 cm -20 mm
Original - 8 mm
Painting -20mm
X - scale factor
20 = X * 8
X = 20/8 = 2.5
The ladybug has been multiplied/ enlarged by a scale factor of 2.5 to draw the painting
Answer:
(x + 1)(x + 4)
Step-by-step explanation:
We want to factor x² + 5x +4 into two binomial factors. Note that 1*4 = 4 and that 1 + 4 = 5, so:
y = x² + 5x +4 = (x + 1)(x + 4)
Answer:
(B)Place compass at point A, and open compass to greater than P.
Step-by-step explanation:
The following steps will be followed in the construction of a Square inscribed in a circle.
- Draw a circle and label the center P.
- Draw the diameter of the circle, labeling the endpoints A and B.
- Construct the perpendicular bisector of the diameter, AB.
- Label the points where the bisector intersects the circle as C and D.
- Connect points A to B to C to D to form the square.
Now to construct a perpendicular bisector of AB, the next step is to place the compass at A and open the compass to greater than the center P of the circle. We do the same at point B.
The correct option is B.
