Answer:

The equality is only true for [tex]a = 0\ and\ 1[/tex], not for all values

Step-by-step explanation:

Given

[tex](\sqrt a)^4 = a[/tex]

Required

Determine if it is valid

[tex](\sqrt a)^4 = a[/tex]

Evaluate the exponent

[tex](a^\frac{1}{2})^4 = a[/tex]

[tex]a^\frac{1*4}{2} = a[/tex]

[tex]a^2 = a[/tex]

Rewrite as:

[tex]a^2 - a = 0[/tex]

Factorize

[tex]a(a- 1) = 0[/tex]

[tex]a =0\ or\ a - 1 = 0[/tex]

[tex]a =0\ or\ a = 1[/tex]

The equality is only true for [tex]a = 0\ and\ 1[/tex], not for all values

The probability of choosing a red card or a face card from a deck of cards will be 19/26.

Its simple notion is that something will most likely occur. The favorable event's proportion to the overall number of occurrences.

Then the probability of choosing a red card or a face card from a deck of cards will be

We know that there are 52 cards in a deck of cards.

Then the total event will be

Total events = 52

And we know that a face card means a king, queen, or jack.

And the favorable event will be

Favorable event of face card = 12

Favorable event of red card = 26

Then the probability will be

P = 12 / 52 + 26 / 52

P = 3 / 13 + 1 / 2

P = 19 / 26

Answer:

612 cm²

Step-by-step explanation:

Total surface area = area of all the nets in that make up the shape

✔️There are 2 equal rectangles of the following dimensions:

L = 10 cm

W = 4 cm

Area = 2(10*4) = 80 cm²

✔️There are 2 equal rectangles of the following dimensions:

L = 10 cm

W = 17 cm

Area = 2(10*17) = 340 cm²

✔️There are 2 equal rectangles of the following dimensions:

L = 4 cm

W = 17 cm

Area = 2(17*4) = 136 cm²

✅Total surface area = 80 + 340 + 136 = 612 cm²

Answer:

The answer is 11.8

Step-by-step explanation:

The value of x and y is 12.2 and 11.8 respectively.

The tangent of an angle is the ratio of the length of the opposite side to the length of the adjacent side.

The sine (sin) of an acute angle in a right angled triangle is the ratio between the side opposite the angle and the hypotenuse of the triangle.

According to the given question.

We have a right angled triangle.

In which one angle is 44 degrees and hypotenuse is 17 units.

Here,

With respect to angle 44 degrees the adjacent side is x and the opposite side is y.

Therefore,

Sine of 44 degrees is given by

[tex]sin44^{o} = \frac{opposite\ side }{Hypotenuse}[/tex]

[tex]\implies sin44^{o} = \frac{y }{17}[/tex]

[tex]\implies 0.6946 = \frac{y}{17}[/tex]

[tex]\implies 0.6946 \times 17 = y[/tex]

[tex]\implies y = 11.80[/tex]

[tex]\implies y = 11.8[/tex]

And, tangent of 44 degrees is give by

[tex]tan 44^{o} = \frac{opposite \ side }{adjacent \ side }[/tex]

[tex]\implies tan44^{o} = \frac{y}{x}[/tex]

[tex]\implies tan44^{o} = \frac{11.8}{x}[/tex]

[tex]\implies 0.9657 = \frac{11.8}{x}[/tex]

[tex]\implies x = \frac{11.8}{0.9657}[/tex]

[tex]\implies x = 12.22[/tex]

[tex]\implies x = 12.2[/tex]

Therefore, the value of x and y is 12.2 and 11.8 respectively.

C. [tex] (x +2) ^2 +(y+8)^2 =10 [/tex]

Step-by-step explanation:

Center of the circle (h, k) = (-2, - 8)

Radius [tex] r=\sqrt {10}[/tex]

Equation of circle in center radius form is given as:

[tex] (x - h) ^2 +(y-k) ^2 =r^2 [/tex]

Plugging the values of h, k and r in the above equation, we find:
