Answer:

The function will be exist if and only if :

$\frac{ - x + 3}{2} > 0 \\ = > - x + 3 > 0 \\ = > - x > - 3 \\ = > x < 3 \\ \\ \therefore \bf \: domain \: \: \green{x < 3}$

Luda [366]

Answer: <8.01, 5.60>.

Step-by-step explanation:

Vector:

$v= (r\cos\theta,r\sin\theta)$

, where r = magnitude and $\theta$ = angle .

As per given,

$u=(4\cos 50^{\circ}, 4\sin 50^{\circ})\\\\\approx(4(0.64),4(0.77))\\\\=(2.56, 3.08)$

$v=(6\cos 25^{\circ}, 6\sin 25^{\circ})\\\\\approx(6(0.91),6(0.42))\\\\=(5.46, 2.52)$

Consider

$u+v=(2.56,3.08)+(5.46,2.52)\\\\=(2.56+5.46,3.08+2.52)\\\\=(8.02,\ 5.60)$

Hence, the correct option is <8.01, 5.60>.

10 mi 6 mi b What is the length of the missing leg? b miles

poizon [28]

Answer:

The length of the missing leg:

b = 8 miles

Step-by-step explanation:

Given

c = 10 mi

a = 6 mi

To determine:

The length of the leg b = ?

For a right-angled triangle, with sides a and b the hypotenuse c is defined as:

$c=\sqrt{a^2+b^2}$

We can find the length of the leg b using the formula

$b=\sqrt{c^2-a^2}$

substituting c = 10 and b = 6 in the formula

$b=\sqrt{10^2-6^2}$

$b=\sqrt{100-36}$

$b=\sqrt{64}$

$b=\sqrt{8^2}$

$\mathrm{Apply\:radical\:rule}:\quad \sqrt[n]{a^n}=a$

$b=8$ mi

Therefore, the length of the missing leg:

b = 8 miles

)A spinner is divided into sections of equal size, of which some are red, some are blue, and the remaining are green. The probab

stiv31 [10]

Answer:

40%

Step-by-step explanation:

The probability of the arrow landing on the green section is a 40% chance

This is because there are only 3 sections where one is 50 and the other is 10

To find the green we can create an equation, where x = green section

50 + 10 + x = 100

The equation equals 100 because that's the highest the percentage will go in probability, unless we were told otherwise

60 + x = 100

x = 100 - 60

x = 40
