Answer:
€98.
Step-by-step explanation:
A 30% deposit is 0.30 * 840
= €252.
So there is 840 - 252
= €588 left to pay.
The amount of each monthly instalment
= 588 / 6
= €98.
7ab a - b
-------------- - --------------
a^2 - b^2 a + b
7ab a - b
= -------------- - --------------
(a-b)(a+b) a + b
7ab (a - b)^2
= -------------- - -----------------------
(a-b)(a+b) (a + b)(a-b)
7ab a^2 - 2ab + b^2
= -------------- - -----------------------
(a-b)(a+b) (a + b)(a-b)
7ab - a^2 + 2ab - b^2
= -----------------------------------
(a-b)(a+b)
- a^2 + 9ab - b^2
= -----------------------------------
(a-b)(a+b)
Answer is A. first one
Answer:
D
Step-by-step explanation:
A. false; the diameter of a circle is double the radius
B. false; the diameter of a circle is double the radius
C. false; the diameter of a circle is double the radius
D. true! The diameter is double the radius
Answer:
A. 78,5 in
Step-by-step explanation:
Formula for circumference of the circle is π × diameter.
<h2>:- Question</h2>
Find the circumeference of the circle!
<h2>:- Solution</h2>
Circumeference = π × diameter
= 3,14 × 25 in
= 78,5 in
The circumeference of the circle is 78,5 in
_______________________
The equation of a circle with center (h,k) and radius r is
(x-h)²+(y-k)²=r²
so
given center is (3,-4)
(x-3)²+(y-(-4))²=r²
(x-3)²+(y+4)²=r²
find r² by subsitutiong the point taht it passes through which is (6,5)
so
(6-3)²+(5+4)²=r²
3²+9²=r²
9+81=r²
90=r²
so
(x-3)²+(y+4)²=90 is da equation
4th equation
