Answer:
90°
Step-by-step explanation:
Arc a subtends and angle of 45° to the circumference of the circle
We know that;
An angle subtended by an arc to the center of a circle is twice the angle subtended by the same chord to the center of the circle.
Therefore, if arc a subtends and angle of 45° to the circumference of the circle then;
a will be = 45 × 2
= 90°
Answer:
9 and -4
Step-by-step explanation:
Find two numbers that multiply to be -36 and add to be -5.
That is -9 and 4.
So the factored form of x^2-5x-36 is (x-9)(x+4)
So the x-intercepts are 9 and -4
Answer:
John should build the box 3 cm high.
Step-by-step explanation:
John should build the box 3 cm high because to find the volume you must do length x width x height. To find this you have to multiply the length x width. In this problem 6 would be the length and 2 would be the width. After multiplying those you get 12. You then have to find what number multiplies with 12 to get 36, which is 3. Hope this helped!
Answer:
The absolute change in the height of the water is 9.5 inches
Step-by-step explanation:
Given
--- length
--- width
--- height
--- the volume removed
Required
The absolute change in the height of the water
First, calculate the base area (b):
The height of the water that was removed is:
<em />
<em> i.e. the volume of the water removed divided by the base area</em>
The absolute change in height is:
