Answer:
Step-by-step explanation:
Here you go mate
step 1
x^2+5x-14=0 equation/Question
step 2
x^2+5x-14=0 factor by setting them equal to zero
(x-2)(x+7)=0
answer
x=2 or x=-7
To find the answer, all you must do is convert 14% into a decimal by moving the decimal point two units to the left which will give you the number: 0.14. Multiply 21 by 0.14 and you should get your answer: 2.94. This means 14% of 21 is 2.94.
Answer:
f (x) = a(x - h)2 + k, where (h, k) is the vertex of the parabola. ... When written in "vertex form": • (h, k) is the vertex of the parabola, and x = h is the axis of symmetry.
Answer:
I'm not really sure but I think it's 160°
Step-by-step explanation:
ST is equal to 30° x 2 so 60°
Now, you'll do 60+140 which equals to 200°
A full circle is 360° so, 360 - 200 = 160°
Ps: I'm not sure but I think this is correct.
I hope this helps :)
Hi there :-)
The formula of the simple interest is
I=prt
your question ask to find r which is interest rate you do that by dividing each side by (pt) to get
R=I÷pt
Now solve to get the interest rate
R=562.5÷(1,500×5)
R=0.075×100 multiply by 100 to get it as percentage
R=7.5%
Hope it helps:-)
