Answer:

The actual height of the object is 200.2 cm

Step-by-step explanation:

The parameters given are;

The actual height = 154 cm.

The height in the picture = 10 cm.

The height of the object = 13 cm

The scale of the picture is 154 is to 10 or 154:10 which is equivalent to 77:5

Therefore the scale of the actual object height to the image height = 77:5

Where the image of the object = 13 cm

Let the height of the actual object = X, then we then have;

$\dfrac{77}{5} = \dfrac{X}{13}$

$X = 13 \times \dfrac{77}{5} = \dfrac{1001}{5} = 200\frac{1}{5} \ cm = 200.2 \ cm$

The actual height of the object = 200.2 cm.

Which of the following expressions are equivalent to 7.2 ÷ -8.1 ÷ -3.7?

Inessa05 [86]

Step-by-step explanation:

7.2 / (-8.1) / (-3.7) = Positive

A = (-7.2) / (-8.1) / (-3.7) = Negative

B = (-7.2) / (8.1) / (3.7) = Negative

Hence the answer is C, none of the above.

Find the center and radius for the circle, given the equation: x^2-14x+y^2+8=16

Strike441 [17]

You can do this by completing the square

x^2 - 14x + y^2 + 8 = 16

(x - 7)^2 - 49 + (y + 4)^2 - 16 = 16

(x - 7)^2 + (y + 4)^2 = 16 + 16 + 49 = 81

so the center is at (7 , -4) and radius = sqrt81 = 9

Divide 4/2 so you get 2= n over 4 then multiply 2 by 4 and then multiply n over 4 by 4 you’ll get 4*2=n, multiply 4 and 2.

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