1/3+1/4 = 4/12 + 3/12 = 7/12
Answer:
SA = π3^2 + π3(7.5)
Step-by-step explanation: r is radius and L
is r*l/2
so 3*5/2=15/2=7.5
seriously look at a problem more carefully and memorise your formulas!
Answer/Step-by-step explanation:
2. Using two pairs of values, (0, 59) and (2,000, 51),
3. The y-intercept is the value of y when x = 0. Thus, x = 0, when y = 59. Therefore,
y-intercept (b) = 59
4. To write an equation in slope-intercept form, simply substitute m = -¹/250, and b = 59, in
✅
5. Substitute x = 5,000 in .
At an altitude of 5,000 ft, temperature would be 39°F
Answer:
-53
/14
Step-by-step explanation:
-2=-x+x square-4
firstly regroup the equation
x square-2x+x-2=0
x square-x-2=0
multiply the first term by the last term.(I.e x square multiply by -2=-2x square)
product of factor = -2x 1
sum of factor= -2x+1(x)= -1
x square -2x+x-2=0
open the bracket:
x(x-2)+1(x-2)=0
x=1 or x=-2
Therefore; x=-1 or x=2
