Answer:

1.x=10 and x=−2.

2. the answer is x=7,-1

3.=3, =1

Step-by-step explanation:

1.Since it is a quadratic equation, then it has, at the most, two solutions because the square root of the variable has a positive and negative value. Thus, the solutions to the given equation are x=10 and x=−2.

2.Once in standard form, identify a, b, and c from the original equation and plug them into the quadratic formula. the you would simplify the equation.and the last thing that is to separate the equation.

Given:

Radius of the cylinder = 5 in

Height of the cylinder = 30 in.

To find:

The surface area of the cylinder.

Solution:

The surface area of the cylinder is:

[tex]SA=2\pi r^2+2\pi rh[/tex]

Where, r is the radius and h is the height of the cylinder.

Putting [tex]r=5,h=30,\pi=3.14[/tex] in the above formula, we get

[tex]SA=2(3.14)(5)^2+2(3.14)(5)(30)[/tex]

[tex]SA=2(3.14)(25)+942[/tex]

[tex]SA=157+942[/tex]

[tex]SA=1099 [/tex]

Therefore, the surface area of the cylinder is 1099  square inches.

Answer: (d)

Step-by-step explanation:

According to the triangle law of vector addition, the two vectors acting on a body are represented by the two sides of a triangle taken in order then the third side gives the resultant of the two vectors taken in the opposite order.

Here, option (d) aligns well with the triangle law of vector addition. The third side is in opposite order w.r.t the two vectors represented by the two sides of triangle i.e. [tex]3\vec{u}-2\vec{s}[/tex]

Answer:

I am pretty sure the answer would be 6p+3

Step-by-step explanation:

I got this by solving (6 multplied by p) +3

You have to multiply 6 by p which will give you 6p

Than, you just add the +3 to the equation

This together would give you

(6*p) +3 = 6p+3.

Hopefully this answered your question!

Answer:

0.98

Step-by-step explanation:

Assuming the number of questions on all the tests is 10,

9+9+10+10+10 / 50

You get 50 by doing 5 quizzes x 10 questions per quiz.

48/50 = 0.98

pi = 3.14

Answer: Yes, by SAS

Step-by-step explanation:

This is because, two sides are equal and one angle is equal.

And also there is one angle between 2 sides, so it’s SAS

Answer:

26.39

Step-by-step explanation:

It's a right triangle, so because of how trigonometric functions work:

[tex]\sin B = \frac{4}{9}\\B = \arcsin\frac{4}{9} \approx 26.3878^\circ[/tex]

There's really no better way than to input it into a calculator.

So the only thing left is to round to the nearest hundredth.

Answer: [tex]3.675\ in.[/tex]

Step-by-step explanation:

Given

Wood shrinks 5% over the period of time

The width of the gap is 3.5 inch

The length of the rectangular block is 5 inch

So, the builder cut the rectangular block 5% bigger to compensate for the shrinkage

Required length is

[tex]\Rightarrow 3.5+5\%\times 3.5\\\Rightarrow 3.5+0.05\times 3.5\\\Rightarrow 3.5[1+0.05]\\\Rightarrow 3.675\ in.[/tex]

Answer:

84 in²

Step-by-step explanation:

[tex]S_{A} = A_{L}+A_{base}[/tex]

[tex]S_{A}[/tex] = 4(1/2 * 6 * 4) in² + 6 in * 6 in

[tex]S_{A}[/tex] = 2(24) in² + 36 in²

[tex]S_{A}[/tex] = 48 in² + 36 in²

[tex]S_{A}\\[/tex] = 84 in²

Answer:

It would be 9 units.

Step-by-step explanation:

So to find the distance between two points, first start at one of the points then see how much distance there is between it and 0.

So taking 7 to start with, you would need to walk 7 units to get to 0.

However, we still need to get the distance till -2. So, we need to walk another 2 steps back, so it would be 9 units of walking in total.

3rd option

Step-by-step explanation:

Given

y + [tex]\frac{3}{4}[/tex] = 6 ( multiply through by 4 to clear the fraction

4y + 3 = 24 ( subtract 3 from both sides )

4y = 21 ( divide both sides by 4 )

y = [tex]\frac{21}{4}[/tex] = 5 [tex]\frac{1}{4}[/tex]
