choice B
Answer:
26 cm
Step-by-step explanation:
The area of a trapezium is
A = 1/2 (b1+b2)*h where b1 and b2 are the lengths of the bases
910 = 1/2 ( 21+49) h
910 = 1/2 (70)h
910 = 35h
Divide by 35
910/35 = 35h/35
26 = h
Answer:
f(3)=16
Step-by-step explanation:
f(x)= x² +7
f(3)= (3)² +7
f(3)=9+7=16
Answer:
She sells all of them.
Step-by-step explanation:
First find the slope:
The slopes of perpendicular lines must multiply to -1.
-9m = -1 ----> m = 1/9
Next, use point-slope form:
y - y1 = m(x-x1) , where given point (0,5) is (x1,y1)
y - 5 = (1/9)(x - 0)
Finally, solve for y to put it in slope-intercept form:
y = (1/9)x + 5
