Answer: No
Step-by-step explanation:
An acute triangle would have three acute angles. An obtuse angle would have two acute and one obtuse. Finally a right triangle would have two acute one right.
Hello,
First we must use the property of the sum of perfect squares:
X^2 -14x +y^2 +10y+65 =0
Adding 7^2 and -7^2
x^2 -14x+7^2-7^2 +y^2+10y+65=0
x^2 -2.7x +7^2 -49 +y^2+10y+65=0
(X-7)^2 +y^2+10y+16=0
Adding 5^2 and -5^2
(X-7)^2 +y^2 +10y+5^2-5^2+16=0
(X-7)^2 +y^2+2.5y+5^2 -25 +16=0
(X-7)^2+ (y+5)^2 -9 = 0
(X-7)^2 +(y+5)^2 = 9
(X-7)^2+(y+5)^2 = 3^2
Center = (7, -5)
R = 3
The circle is in the 4 quadrant.
Answer:
Find the height of a cylinder with radius 25 cm and surface area 8953.54 cm².
O = 2·pi·r^2 + 2·pi·r·h --> h = O/(2·pi·r) - r = 8953.54/(2·pi·25) - 25 = 32.00 cm
Find the volume of a rectangular prism that measures 47 meters long, 24 meters wide, and 33 meters high.
V = a·b·c = 47·24·33 = 37224 m³
Find the surface area of a square pyramid with dimensions 6 ft by 6 ft, and slant height 9 ft.
O = a^2 + 2·a·hs = 6^2 + 2·6·9 = 144 ft²
Answer:
$1070
Step-by-step explanation:
Put 75 where x is and do the arithmetic.
c = 13·75 +95 = 1070
The cost for 75 people is $1070.
