In the diagram c || d identify three numbered angles that have a measure of 70°

Answer:

Discontinuity at (1, 7), zero at (-4/3 , 0)

Step-by-step explanation:

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

                        x = -4/3   or 1

But x = 1 makes f(x) undefined, so there is discontinuity at x = 1

and there is a zero at x = -4/3.

3x + 4 = 3(1) + 4 = 3 + 4 = 7

If you were to graph this function, then you would get the line y = 3x + 4 with a hole at (1, 7).   The line would cross the x-axis at (-4/3, 0) with discontinuity at (1, 7)

Step-by-step explanation:

Take two empty ice cream cups. Make a small hole at the bottom of each cup and pass a long thread through them. Tie a knot or match stick at each end of the thread so that the thread does not slip out through the holes. ... Thus, sound can travel through a solid

Answer:

Answer:

y = 0

Step-by-step explanation:

subsitute x = -3 into y = x^2 - 7x + 12

y = -3^2 - 7 x  -3 + 12

  = 9 - 21 + 12

  =  0

Answer: 42

Step-by-step explanation:

y= (-3)^2 -7(-3) +12

= (9) -(-21) +12

= 9+21+12

= 42

[tex]area = length \times width \\ = (2x + 7)(3x - 4) \\ = (6 {x}^{2} - 8x + 21x - 28) \\ = (6 {x}^{2} + 13x - 28) \: sq \: units[/tex]

The area of the rectangle PQRS is given by the formula D) 6x²+13x-28.

Any mathematical statement that includes numbers, variables, and an arithmetic operation between them is known as an expression or algebraic expression. In the phrase 4m + 5, for instance, the terms 4m and 5 are separated from the variable m by the arithmetic sign +.

The area of a rectangle is given by the formula:

A = l × w, where l is the length and w is the width.

In this case,

The length is 2x + 7 and the width is 3x - 4.

Therefore, the area of the rectangle is:

[tex]A = (2x + 7)(3x - 4)\\A = 6x^2 - 8x + 21x - 28\\A = 6x^2 + 13x - 28[/tex]

Therefore, the expression that describes the area of rectangle PQRS is D) 6x²+13x-28.

Answer:

X:Y = 3/20

Step-by-step explanation:

Given -

Length of rectangle P = 80

Width of rectangle P = X

Length of rectangle Q, Y  = 25% more than the length of rectangle P

Length of rectangle Q = 1.25 X

Width of rectangle Q = 9

Area of rectangle P = 80X

Area of Q = 0.75 % of area of rectangle P

Area of Q = 0.75 *  80X = 60 X

or 9Y = 60 X

X:Y = 9/60

X:Y = 3/20

Answer:

She will be able to pay off her loan completely in approximately 50 months

Step-by-step explanation:

The amount Esme earns as net salary = $2,400

The amount she already has in a savings account = $100

The amount she would be able to add to her savings account every month = $100

The cost of the car Esme plans to purchase on the no interest loan, A = $20,000

The amount she will make as payment on the loan every month, P = $300 per month

Let 'x' represent the number of month Esme will be able to pay off her loan completely, we have

The number of month Esme will have enough money to pay off her loan completely is given by the following equation;

20,000 = 100 + 300 × x + 100 × x = 100 + 400·x

∴ x = (20,000 - 100)/400 = 49.75

Therefore, the number of months she will be able to pay off her loan completely = 49.75 months ≈ 50 months.

Answer:

D

Step-by-step explanation:

The boat is a distance of 25 miles far away from the dock. which is the correct would be an option (D).

A right triangle is defined as a triangle in which one angle is a right angle or two sides are perpendicular.

A boat leaves the dock and travels 7 miles due south, then 24 miles due west which is given in the question.

According to Pythagoras's theorem,

In a right-angled triangle, "the square of the hypotenuse is equal to the sum of the squares of the other two sides."

perpendicular²+base²=hypotenuse²

The hypotenuse = c

Here , perpendicular = 7 and base = 24

⇒ 24² + 7² = c²

⇒ 576 + 49 = c²

⇒ 625 = c²

⇒ c² = 625

⇒ c = 25

Therefore, the boat is a distance of 25 miles far away from the dock.

Answer:

The option C

Step-by-step explanation:

In the option A and B the image is been showed in either up-side down or mirror image. Only the option C has the image in a correct way and just moved the shape in a different position

The solution is Option C.

The image which shows a translation is Figure C.

What is Translation?

A translation moves a shape up, down, or from side to side, but it has no effect on its appearance. A transformation is an example of translation. A transformation is a method of changing a shape's size or position. Every point in the shape is translated in the same direction by the same amount.

Given data ,

Let the figure be represented as F

Now , the figure is translated up , down, or from side to side

The size of the figure does not change on translation

a)

The figure A has been inverted and it is not a transformation of translation

So , the Figure A is false

b)

The Figure B has been reflected by a factor , and reflection changes the coordinates of the figure F

So , Figure F is False

c)

The Figure C is translated by a factor of x to the left and y to downwards

The size of the figure remains the same

So , Figure C is a translation of Figure F

Hence , the figure C is a translation

Answer:

68 %

Step-by-step explanation:

Since we have our mean x = 250 and standard deviation σ = 20, we need to find how many standard deviations away the values 230 and 270 are.

Note x - σ = 250 - 20 = 230 and x + σ = 250 + 20 = 270

The values are one standard deviation away.

So, the values between 230 and 270 lie in the range x - σ to x + σ.

Since the batting averages are approximately normally distributed and for a normal distribution, 68 % of the values lie in the range x - σ to x + σ.

So, 68 % of Braves players fall between 230 and 270.
