what are the zeros of the function?
f(x)=x^2+7x-60

Answers

Answer 1

Answer:

(-12, 0) and (5, 0)

Step-by-step explanation:

f(x) = x² + 7x − 60

Here, a = 1, b = 7, c = -60.  Using the AC method, we need to find factors of a×c that add up to b.

12 × -5 = -60

12 + -5 = 7

The factors are 12 and -5.

f(x) = (x + 12) (x − 5)

The zeros are:

x + 12 = 0, x − 5 = 0

x = -12, x = 5

The zeros are (-12, 0) and (5, 0).

Answer 2

[tex]x^2+7x-60 =0\\x^2-5x+12x-60=0\\x(x-5)+12(x-5)=0\\(x+12)(x-5)=0\\x=-12 \vee x=5[/tex]

Step-by-step explanation:

We are to determine the factor of the polynomial function [tex]f(x)[/tex] which is graphed on the given coordinate plane.

We know that if the zeros (or intercepts) of an equation are [tex] r _ 1 [/tex] and [tex] r _ 2 [/tex] then the factors for this equation will be [tex] ( x - r _ 1 ) [/tex] and [tex]( x - r _ 2 ) [/tex].

From the graph, we can see that it intercepts the x axis at [tex]1[/tex] and [tex]6[/tex]. So the roots will be [tex](x-1)[/tex] and [tex](x-6)[/tex].

Therefore, the correct answer option is B. (x - 1).

Answers

Answer:

168°

Step-by-step explanation:

∠QRS is an angle formed by 2 chords of the circle and is half the measure of its intercepted arc QS, that is

m QS = 2 × 84° = 168°

Applying the inscribed angle theorem, the measure of arc QS is: 168°.

What is the Inscribed Angle Theorem?

According to the inscribed angle theorem, the measure of an inscribed angle in a circle equals half of the measure of the intercepted arc.

Based on the inscribed angle theorem,

arc QS = 2(m∠QRS)

arc QS = 2(84)

arc QS = 168°

Why do you think the acceleration due to gravity is represented by a negative number?

Answers

Answer:

Step-by-step explanation:

Acceleration due to gravity is the rate at which an object changes its velocity due to the force of gravity.On Earth, the average acceleration due to gravity is -9.81 m/s².The acceleration due to gravity is ALWAYS negative.  Any object affected only by gravity (a projectile or an object in free fall) has an acceleration of -9.81 m/s², regardless of the direction.

The acceleration is negative when going up because the speed is decreasing.  The acceleration is negative when going down because it is moving in the negative direction, down.  Even at the top of the path where the instantaneous speed is 0 m/s, the acceleration is still -9.81 m/s². ...

Step-by-step explanation:

Given

[tex]\sqrt[3]{16x^{7} } * \sqrt[3]{12x^{9} }[/tex]

Required

Products of both

To do this, we have to apply the laws of indices,

Follow the highlighted steps

Step 1: Multiply both parameters directly

Since they both have the same roots, they can be multiplied directly according to the law of indices

[tex]\sqrt[3]{16x^{7} } * \sqrt[3]{12x^{9} }[/tex] becomes

[tex]\sqrt[3]{16x^{7} * 12x^{9} }[/tex]

Step 2: Apply the 1st law of indices

First law of indices states that

[tex]x^{a} * x^{b} = x^{a + b}[/tex]

So, [tex]\sqrt[3]{16x^{7} * 12x^{9} }[/tex] becomes

[tex]\sqrt[3]{16x^{7} * 12x^{9} }[/tex] = [tex]\sqrt[3]{16 * 12 * x^{7} * x^{9} }[/tex]

[tex]\sqrt[3]{16x^{7} * 12x^{9} }[/tex] = [tex]\sqrt[3]{16 * 12 * x^{7+9} }[/tex]

[tex]\sqrt[3]{16x^{7} * 12x^{9} }[/tex] = [tex]\sqrt[3]{16 * 12 * x^{16} }[/tex]

[tex]\sqrt[3]{16x^{7} * 12x^{9} }[/tex] = [tex]\sqrt[3]{192 * x^{16} }[/tex]

Step 3: Rewrite the expression

[tex]\sqrt[3]{192 * x^{16} }[/tex] = [tex]({192 * x^{16} })^{\frac{1}{3} }[/tex]

Step 4: Expand the Expression in bracket

[tex]({192 * x^{16} })^{\frac{1}{3} }[/tex] = [tex]({64 * 3* x^{15} * x^{1} })^{\frac{1}{3} }[/tex]

Break down into bits

[tex]({192 * x^{16} })^{\frac{1}{3} }[/tex] = [tex]64^\frac{1}{3} * 3^\frac{1}{3} * (x^{15})^\frac{1}{3} * (x^{1})\frac{1}{3}[/tex]

[tex]({192 * x^{16} })^{\frac{1}{3} }[/tex] = [tex](4^{3}) ^\frac{1}{3} * 3^\frac{1}{3} * (x^{15})^\frac{1}{3} * (x^{1})\frac{1}{3}[/tex]

Answers

Answer:

The probability that the student scored an A is : 0.778

Step-by-step explanation:

There are 55% boys and 45% girls

So, No of boys is: 55/100

No of girls is: 45/100

So, total no of girls are: 45

Since 35% of the girls scored A on test

No of girls who scored A on test = 35

The probability that the student scored an A is: 35/45

The probability that the student scored an A is : 0.778

Answer:

[tex]P(A | B)=\frac{7}{9}=0.778[/tex]

Step-by-step explanation:

Let's call B the event that consists of the selected student being a girl

Call A to the event in which the selected student obtained an A.

Then we look for the probability that A will occur given that B. That is, we look for P(A | B)

This is a conditional probability and is calculated using the following formula

[tex]P(A | B)=\frac{P(A\ and\ B)}{P(B)}[/tex]

In this case

[tex]P(B)=0.45\\P(A\ and\ B)=0.35[/tex]

So

[tex]P(A | B)=\frac{0.35}{0.45}[/tex]

[tex]P(A | B)=\frac{7}{9}=0.778[/tex]

Find the slope of DE and FG

Answers

slope of DE would be [tex]\( m_{DE} = \frac{(2c - b)}{(0 - (-a))} = \frac{(2c - b)}{a} \).[/tex]

slope of FG would be[tex]\( m_{FG} = \frac{(0 - c)}{(0 - (a+b))} = \frac{-c}{-(a+b)} = \frac{c}{a+b} \).[/tex]

To find the slope of line segments DE and FG from a trapezoid on a coordinate plane, we can follow these steps:

1. Identify the Coordinates of Endpoints:

  - For DE, identify coordinates D and E.

  - For FG, identify coordinates F and G.

2. Use the Slope Formula:

  - The slope  m  of a line passing through two points [tex]\( (x_1, y_1) \) and \( (x_2, y_2) \) is given by \( m = \frac{(y_2 - y_1)}{(x_2 - x_1)} \).[/tex]

3. Calculate the Slope for DE:

  - Plug the coordinates of D and E into the slope formula.

4. Calculate the Slope for FG:

  - Plug the coordinates of F and G into the slope formula.

Given the coordinates in the image, let's calculate the slopes for DE and FG:

For DE:

- Let's say D has coordinates  (-a, b)  and E has coordinates (0, 2c)

- The slope of DE would be [tex]\( m_{DE} = \frac{(2c - b)}{(0 - (-a))} = \frac{(2c - b)}{a} \).[/tex]

For FG:

In the  Geometry, the triangle is a 3-sided polygon that consists of 3 edges and 3 vertices. The most important property of the triangle is that the sum of the internal angles of the triangle is = to 180 degrees. its property is known as angle sum property of triangle.

We have been given the image of the right triangle and we are asked to find the value of the tan(60) for our given triangle

from we know that tangent represents the relation between opposite or adjacent of the right triangle.

[tex]tan = \frac{opposite}{adjacent}[/tex]

We can see that our adjacent side is not given, but corresponding angle to adjacent side is given that is 30 degrees. So we could conclude that our given triangle is 30-60-90 triangle.

from the sides corresponding to 30-60-90 triangle equals to[tex]x,x\sqrt{3}[/tex] and [tex]2x[/tex] , so the adjacent side for our given triangle will be,

[tex]x\sqrt{3} =8 \sqrt{3\\\\\\[/tex]

[tex]\frac{x \sqrt{3} }{\sqrt{3} } =\frac{8\sqrt{3} }{\sqrt{3} }[/tex]

There are two vertices of the hyperbola, they are placed at (-6,0) and (6,0), so second option is true.

The transverse axis is the segment connecting vertices, this segment is horizontal, so option 3 is false.

The foci are not placed within the rectangular reference box, so this option is false.

The directrices are vertical lines with equations [tex]x=\pm \dfrac{a}{e}[/tex], so this option is true.

Answer:1 2 5

Step-by-step explanation:

Solve the equation by completing the square. Round to the nearest hundredth if necessary. 4x2 + 8x – 32 = 0

Answers

[tex]4x^2 + 8x - 32 = 0\\x^2+2x-8=0\\x^2+2x+1-9=0\\(x+1)^2=9\\x+1=3 \vee x+1=-3\\x=2 \vee x=-4[/tex]

For this case we must solve the following expression by completing squares:

[tex]4x ^ 2 + 8x-32 = 0[/tex]

We divide between 4 on both sides of the equation:

[tex]x ^ 2 + 2x-8 = 0[/tex]

We add 8 to both sides of the equation:

[tex]x ^ 2 + 2x = 8[/tex]

We divide the middle term between 2 and square, this we add to both sides of the equation:

[tex]x ^ 2 + 2x + (\frac {2} {2}) ^ 2 = 8 + (\frac {2} {2}) ^ 2\\x ^ 2 + 2x + 1 ^ 2 = 8 + 1\\x ^ 2 + 2x + 1 ^ 2 = 9\\(x + 1) ^ 2 = 9[/tex]

We apply root to both sides:

[tex]x + 1 =\pm \sqrt {9}[/tex]

We have two roots:

[tex]x_ {1} = \sqrt {9} -1 = 3-1 = 2\\x_ {2} = - \sqrt {9} -1 = -3-1 = -4[/tex]

Answer:

[tex]x_ {1} = 2\\x_ {2} = - 4[/tex]

Which of the following is the equation of a line that passes through (-2,1) and (-4,-3)?

Answers

Answer:

The equation is y= 2x+5

Step-by-step explanation:

Lets find the slope of the line through the points (-2,1) and (-4,-3).

where x1 = -2,  y1= 1,  x2= -4,  y2 = -3.

Now apply slope formula:

m= y2-y1/ x2-x1

m= -3-1/-4-(-2)

m = -4/-4+2

m= -4/-2

Divide the term by 2:

m = 2

Now we will apply point slope formula:

y-y1 = m (x-x1)

Now substitute the values in the formula:

y-1=2(x-(-2))

y-1 =2(x+2)

y-1=2x+4

Now combine the constants:

y= 2x+4+1

y=2x+5

So the equation is y= 2x+5 ....

Which fraction is equivalent to 20%?
1/20
2/20
4/20
5/20

Answers

Answer:

4/20

Step-by-step explanation:

20 %

Percent means out of 100

20/100

Divide top and bottom by 10

2/10

We want the denominator to be 20 so multiply the top and bottom by 2

4/20

For this case we must find a fraction equivalent to 20%

We have to:

[tex]\frac {1} {20} =[/tex] 0.05 * 100% = 5%

[tex]\frac {2} {20} =[/tex] 0.1 * 100% = 10%

[tex]\frac {4} {20} =[/tex] 0.2 * 100% = 20%

[tex]\frac {5} {20} =[/tex] 0.25 * 100% = 25%

Thus, the correct option is option C, [tex]\frac {4} {20}[/tex]

Answer:

[tex]\frac {4} {20}[/tex]

HELP!!Use the figure to decide the type of angle pair that describe <6 and<4.

Answers

Angle 6, an acute angle, measures below 90 degrees, reflecting a sharp inclination. Angle 4, a right angle at precisely 90 degrees.

In the geometric configuration, Angle 6 is characterized as an acute angle, signifying that its measure falls between 0 and 90 degrees. Acute angles are typically associated with sharp inclinations, emphasizing a compact angular span. On the other hand, Angle 4 is identified as a right angle, precisely measuring 90 degrees.

Right angles are distinctive for their perpendicular alignment, forming the cornerstone of rectangular shapes and providing structural stability. The significance of Angle 4 lies in its pivotal role in defining perpendicularity within geometric constructs.

This geometric interplay showcases the diversity of angles, with acute angles like Angle 6 emphasizing sharpness and right angles like Angle 4 embodying orthogonality, contributing to the intricacies and precision inherent in geometric relationships.

Answer:

[tex]\frac{3}{4}[/tex]

Step-by-step explanation:

There are 4 steps to complete to go from 0 to 1. Hence each step is:

1 out of 4, or simply  [tex]\frac{1}{4}[/tex]

F is located at the 3rd mark, which will be  [tex]\frac{1}{4}+\frac{1}{4}+\frac{1}{4}=\frac{3}{4}[/tex]

Hence, F is located at  [tex]\frac{3}{4}[/tex]

Answer:

F is on [tex]\frac{3}{4}[/tex] on the number line

Step-by-step explanation:

Notice in the image that between 0 and 1 there are 4 subdivisions.

Then divide.

[tex]\frac{1}{4} = 0.25[/tex].

Each subdivision is equal to 0.25 units.

Point F is in the third subdivision.

This means that the distance between 0 and F is:

[tex]\frac{1}{4}*3 = \frac{3}{4} = 0.75[/tex].

Finally F is on [tex]\frac{3}{4}[/tex] on the number line
