Draw a pair of adjacent supplementary angles so that one has a measure of 15 degrees
Nat2105 [25]

Answer:

the best way to to do this would be to use a protractor, if you don't have one you would have to guess on the 15 degrees, but it would be a very small angle

Rewrite each of the following sentences using logical connectives. Assume that each symbol!, x₀, n, x, B represents some fixed o
katrin [286]

Answer:

a) (f\  has\  a\  relative \ minimum \ at\  x_{0} ) ∧ (f\ is\ differenciable\ at\ x_{0} ) ⇒ f^{'} (x_{0} )=0.

b) (n\ is\ prime) ⇒ (n=2) ∨ (n\  is \ odd).

c) R\ is \ irreflexive\ ⇒ (R\ is\ symmetric) ∧ (R\ is\ transitive).

d) detB=0 ⇒ (B \ is\ square) ∧ (B\ is\ not\ invertible).

e) f\ has\ a\ critical\ point\ at \ x_{0} ⇔ (f^{'}(x_{0})=0) ∨ () \ f^{'}(x_{0}) \ does\ not\ exist.

f) 2n ∨ n>4 ⇒ 2.

g) 6\geq n-3 ⇔ n>4 ∨ n>10.

h) x \ is \ cauchy ⇒ x\ is\ convergent.

i) \lim_{x \to \ x_{0}} f(x)=f(x_{0}) ⇒ f\ is\ continous\  at \ x_{0}.

j) (f\ is\ diferenciable\ at\ x_{0}) ∧ (f\ is\ increasing\ at\ x_{0}) ⇒ f^{'}(x_{0})>0.

Answer with proper units too!
EastWind [94]

Answer:

Step-by-step explanation:

1. Area of a parallelogram = base * height

 area = 10 * 4 = 40 in squared

perimeter = 2(a + b)

perimeter = 2 * (5 + 10) = 2 * 15 = 30in

2. Area of triangle = 1/2 * base * height

area = 1/2 * 21 * 8 = 84 cm squared

perimeter = sum of outer perimeters

perimeter= 10cm + 17cm + 21cm = 48cm

3.  area of trapezium = 1/2 * (a+b) * h

 area = 1/2 * (6+12) * 4 = 36ft squared

 perimeter = sum of outer perimeters

 perimeter = 5ft + 6ft + 12ft + 5ft = 28ft
