this is a little difficult for me

Answer:

1. Slope= 2

2. [tex] \frac{b - 2}{4 - 2} = 2[/tex] or [tex] \frac{8 - 2}{a - 2} = 2[/tex]

3. a= 5

4. b= 6

Step-by-step explanation:

The slope of a straight line between any two points of the line would be the same. This means that calculating the slope of the line using point (2, 2) and (6, 10) would give us the same slope value when calculating with points (4, b) and (6, 10) for example.

Formula

[tex]\boxed{\text{slope} = \frac{y_1 - y_2}{x_1 - x_2} }[/tex]

Q1. Since we two pairs of known coordinates, let's make use of them in the slope calculation.

Slope of line

[tex] = \frac{10 - 2}{6 - 2} [/tex]

[tex] = \frac{8}{4} [/tex]

= 2

Q2-4. Since in the subsequent parts we will eventually have to find the value of a and b, let's form an equation for each of them.

Slope between (2, 2) and (4, b)= slope between (2, 2) and (6, 10)

[tex] \frac{b - 2}{4 - 2} = 2[/tex]

[tex] \frac{b - 2}{2} = 2[/tex]

Multiply both sides by 2:

b -2= 2(2)

b -2= 4

b= 4 +2

b= 6

Using (2, 2) and (a, 8):

[tex] \frac{8 - 2}{a - 2} = 2[/tex]

Multiply both sides by (a -2):

6= 2(a -2)

Expand:

6= 2a -4

Add 4 to both sides:

2a= 10

Divide both sides by 2:

a= 10 ÷2

a= 5

Simon had 4 slices of the total pizza.

In mathematics, a fraction is used to denote a portion or component of the whole. It stands for the proportionate pieces of the whole. Numerator and denominator are the two components that make up a fraction. The numerator is the number at the top, and the denominator is the number at the bottom.

There are several fraction examples in daily life, including:

1. If a pizza is split into two equal pieces, each piece represents half of the entire pizza.

2. Each piece of a watermelon slice that is divided into three equal pieces makes up one-third of the whole.

In this question , the ratios given are 5 : 1 : 2

Thus the total is 5 + 1 + 2 = 8

Since Simon's share is 2/8 th of the total

Thus the required fraction is 2 / 8 × 16

From the given figure, it can be seen that there are two circles with centers A and B respectively.

The circle with the center A is larger in size than the circle with center B. Points P, Q and E lie on the surface of the circle having center A and R, S, C and T points lie on the circle having center B.

What are Tangents?

A line that only touches a circle or an ellipse at one point is said to be divergent in geometry. If a line contacts a curve at point P, that point is referred to as the point of tangency. In other words, it is described as the line that, at that particular location, indicates the slope of a curve. The following methods can be used to find the tangent equation in differential geometry:

As we are aware, the gradient of the curve at any given location on the curve is equal to the gradient of the tangent to the curve. The following is how to determine the tangent equation of the curve y = f(x):

Utilizing the differentiation principles, determine the gradient function's derivative.

To determine the tangent's gradient, the derivative should be changed to include the provided point's x-coordinate

Find the tangent equation by substituting the provided coordinate point and the gradient of the tangent into the straight-line equation (in a slope-point formula).

Circle's Tangent

A closed, two-dimensional form, a circle is also a curve. The radius of the circle or the line from the center O to the point of tangency is always vertical or perpendicular to the tangent line AB at P, i.e., OP is perpendicular to AB as illustrated in the accompanying picture.

Geometric Tangent

Here, "AB" stands for the tangent, "P" for the point of tangency, and "O" for the circle's center. The OP is the radius of the circle.

The value of angle T is 65°

In this question, we have been given sin 25=cos T

We need to find the value of T.

Assuming angle in degrees the value of trigonometric function would be,

sin 25 =  0.4226

As we have been given sin 25=cos T,

cos T =  0.4226

So angle T would be,

⇒ T = arccos( 0.4226)

⇒ T = cos^(-1)( 0.4226)

Answer:

Only 6 match your answer choices.

Step-by-step explanation:

Solve for x:

x^3 - 5 x^2 - 8 x + 12 = 0

The left-hand side factors into a product with three terms:

(x - 6) (x - 1) (x + 2) = 0

Split into three equations:

x - 6 = 0 or x - 1 = 0 or x + 2 = 0

Add 6 to both sides:

x = 6 or x - 1 = 0 or x + 2 = 0

Add 1 to both sides:

x = 6 or x = 1 or x + 2 = 0

Subtract 2 from both sides:

Answer: x = 6 or x = 1 or x = -2

Answer:19

Step-by-step explanation:

The number of dimes and nickels in her collection are 296 and 108 respectively.

She had collected 540 coins. which were worth $60.

She counted 100 quarters in her saving.

The number of dimes and nickel in her collection can be solved as follows:

Therefore,

let

x = number of dimes

y = number of nickels

number of quarters = 100

Therefore,

x + y + 100 = 504

x + y = 504 - 100

x + y = 404

Hence,

0.1x + 0.05y + 100(0.25) = 60

0.1x + 0.05y  = 60 - 25

0.1x + 0.05y  = 35

combine the equation

x + y = 404

0.1x + 0.05y  = 35

Multiply equation(i) by 0.1

0.1x + 0.1y = 40.4

0.1x + 0.05y  = 35

subtract equation(ii) from equation(i)

0.05y = 5.4

divide both sides by 0.05

y = 5.4 / 0.05

y = 108

x = 404 - 108

x = 296

Therefore,

Number of dimes = 296

The speed of the cyclist and the walker is 25 miles per hour and 16.67 miles per hour, respectively.

Speed describes how fast an object moves. It can be measured as distance over time.

speed = distance / time

Let x be the speed of the walker and 1.5x is the speed of the cyclist.

If they start "moving simultaneously in the same direction" from the same point and, after 1.5 hours, the distance between them is 12.5 miles, then

distance traveled by cyclist = distance traveled by the walker + 12.5 miles

cyclist's speed(time) = walker's speed(time) + 12.5

1.5x(1.5 hours) = x(1.5 hours) + 12.5
