Answer:

No real solutions.

The given equation has no real solutions.

We have given that the quadratic equation

[tex]-9m^2-8m-3=0[/tex]

For this equation: a=-9, b=-8, c=-3

[tex]-9m^2-8m-3=0[/tex]

Step 1: Use quadratic formula with a=-9, b=-8, c=-3.

[tex]x=\frac{-b \±\sqrt{b^2-4ac}} {2a}[/tex]

Therefore we have,

[tex]x=\frac{-b \±\sqrt{b^2-4ac}} {2a}[/tex]

[tex]x=\frac{-(-8)\±\sqrt{(-8)^2-4(-9)(-3)} }{2(-9)}[/tex]

[tex]x=-\frac{4}{9} -i\frac{\sqrt{11} }{9}[/tex] and [tex]x=-4/9+i\frac{\sqrt{11} }{9}[/tex]

This equation has no real solutions.

There are 70 small boxes and 55 big boxes.

Let x = small box

Let y = large box

The equation will be:

x + y = 125 ....i

25x + 55y = 4775 ..... ii

From equation i, y = 125 - x.

25x + 55y = 4775

25x + 55(125 - x) = 4775

25x + 6875 - 55x = 4775

Collect like terms

25x - 55x = 4775 - 6875

30x = 2100

x = 2100/30

x = 70

Since x + y = 125

y = 125 - 70 = 55

Therefore, there are 70 small boxes and 55 big boxes.

The number of seconds Suzy will pick up the signal if she starts walking toward the coffee shop at a rate of 3 ft/sec from her office building 180 ft away is 40 seconds

After how many seconds will she pick up the signal between her office building and the coffee shop = (Distance between her office building and the coffee shop - Signal distance) / Suzy's speed

= (180 ft - 60 ft) / 3 ft/sec

= 120 ft / 3 ft/sec

= 40 seconds

After how many seconds will she lose the signal = Signal distance / Suzy's speed

= 60 ft / 3 ft/sec

= 20 seconds

Therefore, If she keeps on walking past the coffee shop, she will lose the signal after 20 seconds.

Answer:

The correct answer is 4.167

Step-by-step explanation:

According to the given scenario, the calculation of the Cp i.e. measure of potential capability is as follows;

= (USL - LSL) ÷ 6 × standard deviation

= (3.05 inches - 1.80 inches) ÷ 6 × 0.05

= 1.25 ÷ 0.3

= 4.167

hence, the calculation of the Cp i.e. measure of potential capability is 4.167

-1 × (-6) = 6  ( because of multiplicative property of -1)

0 ×(-76.3) = 0 (zero property of multiplication)

(3x)y = 3(xy)   (commuative property)

0.3 × (-3) = -3 × 0.3 ( commutative property)

As we know that,

The commutative property is a math rule that says that the order in which we multiply numbers does not change the product.

The associative property is a math rule that says that the way in which factors are grouped in a multiplication problem does not change the product.

Identity property states that a number, known as the identity, can be added to, subtracted from, multiplied by, or divided into a number without changing the number.

Zero property of multiplication is defined as “when we multiply any number by zero, the resulting product is always a zero”.

Multiplicative property of -1 atates that any number multiplied by -1 gives the same but with its opposite sign.

From the given example we can say that

-1 × (-6) = 6  ( because of multiplicative property of -1)

0 ×(-76.3) = 0 (zero property of multiplication)

(3x)y = 3(xy)   (commuative property)

0.3 × (-3) = -3 × 0.3 ( commutative property)

Answer: It's the other way around and it is because 10 x 10 is adding 10+10+10+10+10+10+10+10+10+10, while 11x9 is just 9 11s added together.

The other factor of the quadratic equation [tex]6x^{2} -7x+2[/tex] is 3x-2. Since it is a quadratic equation we can get the other factor by factorization.

Factorization of quadratic equation is a way of finding the roots of the equation.The simple method of factorizing is we first find the product of the coefficient of [tex]x^{2}[/tex] and the constant, then we have to get the product by rearranging the coefficient of x, if the constant has a positive sign then we try to get the product by sum and if the sign is negative then we try to get the product by subtraction. After rearrangement we divide the equation in two parts and take the common factors from each part.

One of the factors of the equation is 2x-1, we have to find the other factor.

[tex]6x^{2} -7x+2=0\\6x^{2} -3x-4x+2=0\\3x(2x-1)-2(2x-1)=0\\(2x-1)(3x-2)[/tex]

The other factor of the equation is 3x-2.

The bean bag’s path is part of a curve that is a parabola and to the nearest second, the bean bag was in the air for 1 second(s).

Projectile motion is the motion of the body, when it is thrown in the air taking the action of gravity on it.

The parametric equation for x and y can be given as,

[tex]x =x_o+ v_o\cos(\theta)t \\y =y_o -\dfrac{1}{2}at^2 + (v_o\sin(\theta))t[/tex]

Here, (vo) is the initial speed, (h) is the height and θ is the angle of throw.

The player throws a bean bag from the height of 3 feet with an initial velocity of 34 feet per second at an angle of 30º.

Let suppose the time is t second. Thus, the parametric equation that represents this situation are,

[tex]x = (34\cos(30^o)t \\y = -16t^2 + (34\sin(30^o))t + 3[/tex]

The bean bag’s path is part of a curve. This path is in the form of parabola.

To the nearest second, the bean bag was in the air for 1 second(s).

Thus, the bean bag’s path is part of a curve that is a parabola and to the nearest second, the bean bag was in the air for 1 second(s).

Hence since it was said that within 1 deviation (of the mean) of all people like MATH 123, therefore the number of people that like MATH 123 is:

number of people that like MATH 123 = 68% of the population

Draw an arrow from the origin to (4, 0)

Step-by-step explanation:

u-v+w

= <-3, -4> - <-4, -1> + <3, 3>              

= <4, 0>

We want to perform a sum of vectors and draw the resultant vector. The resultant vector will be <4, 0> and its graph can be seen at the end.

If we see the image, we can write the vectors as:

Now we want to sum:

u - v + w

Remember that in the sum of the vectors we just add (subtract) the correspondent components, then we will have:

u - v + w = <-3, -4> - <-4, -1> + <3, 3> = <-3 + 4 + 3, -4 + 1 + 3> = <4, 0>

Answer:

4t^2 - 28t + 49

Step-by-step explanation:

(2t - 7)^2

Use FOIL.

(2t - 7)^2 =

= (2t - 7)(2t - 7)

= 4t^2 - 14t - 14t + 49

Combine like terms.

= 4t^2 - 28t + 49

(2t - 7)² on expansion results in 4t² - 28t + 49.

The algebraic equations which can be used for all variables in the equation is called Algebraic identities. These identities used in factorization of polynomial expressions as well as in the computation of algebraic expressions.

Some of the standard algebraic identities are:

(a + b)² = a² + 2ab + b²

(a - b)² = a² - 2ab + b²

a² - b² = (a + b) (a - b)

Here we have the expression (2t - 7)².

Using the second identity (a - b)² = a² - 2ab + b², we can write,

(2t - 7)² = (2t)² - (2 × 2t × 7) + 7²

= 4t² - 28t + 49

Hence the expression (2t - 7)² is expanded to 4t² - 28t + 49 using the algebraic identity (a - b)² = a² - 2ab + b².
