The correct answer to your question is option A

The step by step solution is listed below:

$(2 x^{2} +x+3)+(3 x^{2} +2x+1) \\ \\ 
=2 x^{2} +x+3+3 x^{2} +2x+1 \\ \\ 
=2 x^{2} +3 x^{2} +x+2x+3+1 \\ \\ 
=5 x^{2} +3x+4$

A windshield wiper is 50 cm long. In one sweep it turns through an angle of 115°. Calculate the distance (length) it covers in o

sergeinik [125]

Answer:

The distance in one sweep is 100 cm approximately

Step-by-step explanation:

Here, we want to calculate the distance the wiper covers in one sweep

Mathematically;

we have a structure like an arc of a circle. It is the length of this arc we want to calculate.

The formula for the length of an arc is;

theta/360 * 2 * pi * r

r is the radius which in this case is 50 cm

We have ;

115/360 * 2 * 3.1412 * 50 = 100 cm approximately

A card is drawn from a standard deck of 52 cards. What is the probability of drawing a face card (jack, king, or queen) or a bla

Shkiper50 [21]

Probability of drawing a face card =
4 suits x 3 = 12
$\frac{12}{52} = \frac{3}{13}$
Probability of drawing a black card =
$\frac{26}{52} = \frac{1}{2}$
Hope this helps. - M

The first 5 terms in an arithmetic sequence is 4,2,0,-2,-4

Explanation:

The general form of an arithmetic sequence is

$a(n)=a+(n-1)d$

where a denotes the first term of the sequence, d denotes the common difference.

Here a = 4 and d = -2

To determine the consecutive terms of the sequence, let us substitute the values for n.

To find the second term, substitute n = 2 in the formula $a(n)=a+(n-1)d$

$a(2)=4+(2-1)(-2)$

Simplifying,

$a(2)=4-2=2$

Similarly,

For n = 3,

$a(3)=4+(2)(-2)=0$

For n = 4,

$a(4)=4+(4-1)(-2)\\a(4)=4+(3)(-2)\\a(4)=4-6\\a(4)=-2$

For n = 5,

$a(5)=4+(5-1)(-2)\\a(5)=4+(4)(-2)\\a(5)=4-8\\a(5)=-4$

Thus, the first 5 terms of the arithmetic sequence is 4,2,0,-2,-4

4) n=12 this is because 45/4=11.25 and dividing 135 by 11.25 equals to 12

5) n=2.5 this is because 5/2=2.5 and multiplying 1 by 2.5 equals to 2.5

hope this helps :)
