The measure of the angle ∠CFE is 330°.

Arc length is more accurately described as the length along the perimeter of any circle or curve (arc). The arc length is the measurement of any distance along the curved path that forms the arc.

Arc refers to a segment of a curve or the circumference of a circle. Each of them is shaped like a curve. An arc's length is more than the distance in a straight line between its endpoints (a chord).

The angle ∠CFE is calculated as:-

∠CFE = 360 - ∠CEF

∠CFE = 360 - 30

∠CFE = 330

Hence, the angle ∠CFE is 330°.

Consequently, the yield to maturity of a P7000 bond purchased at 90 with 15 years left to maturity is approximately 6.769%.

The rate of return an investor will receive if they hold the bond until maturity is known as the yield to maturity (YTM) of the bond. We need to know a bond's face value, coupon rate, market price, and time until maturity in order to determine its YTM.

Here,

Given :

Face value (FV) equals P7,000

Discount rate is 6%.

Market price as of today (CP) is $90.

15 years is the time to maturity (T).

To determine the YTM, we can use the bond pricing formula:

CP is equal to (FV * C) / (1 + r)T plus (FV / (1 + r)T)

Where:

(FV * Coupon Rate) / 2r = YTMT = time to maturity in years, where C is the annual coupon payment.

The result of solving the equation is 6.769% for the YTM.

A vertex (plural: vertices) is a point where two or more line segments meet. It is a Corner.

I) we can substitute x + d = 2x + 1 and x + 2d = 11 into the equation for d:

x - 1 = 2x + 1 - x = 2x - x + 1 = x + 1

x = 0

II) The 30th term of this arithmetic sequence is 29.

To solve this problem, we can use the fact that in an arithmetic sequence, the difference between consecutive terms is constant.

(i) Let's call the common difference d. Then we can set up the equation:

x + d = 2x + 1

d = x - 1

Since we know that x; 2x + 1; 11 are three consecutive terms of an arithmetic sequence, we can substitute x + d = 2x + 1 and x + 2d = 11 into the equation for d:

x - 1 = 2x + 1 - x = 2x - x + 1 = x + 1

x = 0

(ii) To find the 30th term, we can use the formula for the nth term of an arithmetic sequence:

an = a1 + (n - 1)d

where a1 is the first term, d is the common difference, and n is the number of the term we want to find.

Substituting the known values into this formula:

a30 = x + (30 - 1)d

a30 = 0 + (29)(1)

a30 = 29

So the 30th term of this arithmetic sequence is 29.

The non zero vector orthogonal to the plane through P,Q and R is ⟨0,18,−9⟩

A non-zero vector orthogonal to the plane through the points P, Q, and R can be found by taking the cross product of two vectors that lie in the plane. One way to do this is to take the difference vector of two of the points, and then take the cross product of that difference vector with the difference vector of the third point.

For example, we can use the difference vector QP = (-2,1,3) - (1,0,1) = (-3,1,2) and the difference vector RP = (4,2,5) - (1,0,1) = (3,2,4)  

The cross product of these two vectors is:

(-3,1,2) x (3,2,4) =⟨0,18,−9⟩

If the graph only touches the x-axis at the x-intercept, then it is said to "touch" the x-axis. This indicates that the graph does not pass through the x-axis at the x-intercept, but rather just touches it.

The x-intercept of a graph is the point at which the graph crosses the x-axis. It is also known as the abscissa. The x-coordinate of the x-intercept is the value where the graph intersects the x-axis.

The x-intercept of a graph is the point at which the graph crosses (or, in some cases, touches) the x-axis. A graph can have one or more x-intercepts. If the graph only crosses the x-axis once, then it has only one x-intercept. If the graph crosses the x-axis twice or more, then it has multiple x-intercepts. In either case, the x-intercepts can be described as either "crosses" or "touches" the x-axis.

A function can be obtained from the table provided with the values of x and y in the form of a y=mx+b equation.

The above equation can be solved by plotting the graph or from table itself and after calculating its y-intercept, the value of y in the form of y= mx+ b can be obtained. Suppose the table has values of x and y as follows:

x: 0   1   2  3

y: 2  4   6  8

However, it can be seen that when x=0, y= 2, so the y-intercept i.e. the value of y obtained at x=0 is 2. And the slope can be calculated as:

William should use 0.625 pounds of peanuts, and 0.375 pounds of cashews in the mixture.

Given that,

The selling price of peanuts= $2.40

The selling price of cashews= $3.20

Let x be the amount of that pound composed of peanuts. (1-x) of that pound is composed of cashews.

The total price of such a pound mix is 2.4x + 3.2(1-x) = 2.7

2.4x + 3.2(1-x) = 2.7

2.4x + 3.2 - 3.2x = 2.7

-0.8x + 3.2 = 2.7

-0.8x = -0.5

x = 5/8 = 0.625 pounds of peanuts, and 1-5/8=3/8= 0.375 pounds of cashews.

We would need more information to answer this question. For example, Sally’s speed.

Step-by-step explanation:

The angle is acute and the answer rounded to the nearest degree is 13.2 degrees for (a) and 71.8 degrees for (b)

(a) To find the acute angle between the lines, we need to find the slope of each line and use the inverse tangent function to find the angle between them. The slope-intercept form of the first line is y = -9x + 5 and the slope-intercept form of the second line is y = 3x - 6.

The slope of the first line is -9 and the slope of the second line is 3. To find the acute angle between the lines, we can use the formula:

angle = atan2(|m1-m2|,1+m1*m2)

where m1 and m2 are the slopes of the lines.

angle = atan2(|-9-3|,1-9*3)

= atan2(6, -24)

= atan2(6/sqrt(24^2+6^2),-24/sqrt(24^2+6^2))

= atan2(6/sqrt(600),-24/sqrt(600))

= atan2(6/24.4987, -24/24.4987)

= atan2(0.244, -0.976)

= atan2(0.244/sqrt(0.244^2+0.976^2),-0.976/sqrt(0.244^2+0.976^2))

= atan2(0.244/1, -0.976/1)

= atan2(0.244, -0.976) = 13.2 degree.

(b) The slope-intercept form of the first line is y = (7-x)/2 and the slope-intercept form of the second line is y = (2-5x)/(-1).

The slope of the first line is -1/2 and the slope of the second line is 5. To find the acute angle between the lines, we can use the formula:

angle = atan2(|m1-m2|,1+m1*m2)

where m1 and m2 are the slopes of the lines.

angle = atan2(|-1/2-5|,1-(-1/2)*5)

= atan2(5.5, -2.5)

= atan2(5.5/sqrt(5.5^2+2.5^2),-2.5/sqrt(5.5^2+2.5^2))

= atan2(5.5/6.1213, -2.5/6.1213)

= atan2(0.901, -0.408)

= atan2(0.901/sqrt(0.901^2+0.408^2),-0.408/sqrt(0.901^2+0.408^2))

= atan2(0.901/1,-0.408/1)

$60 / 6 barbecue sticks = $x / 1 barbecue stick

Where x is the value of 1 barbecue stick.

To find the value of x, we can cross-multiply and divide by 6:

$60 = 6 barbecue sticks * $x/1

$60 = $6x

$x = $10

So, $10 will equal 1 barbecue stick, if $60 = 6 barbecue sticks.

We know that you earned $300, so we can substitute that into the proportion:

$60 / 6 barbecue sticks = $300 / n barbecue sticks

We can cross-multiply and divide by 60:

6 barbecue sticks * $300 = $60 * n barbecue sticks

n barbecue sticks = $300 * 6 / $60

n barbecue sticks = 30

Therefore, you sold 30 barbecue sticks.

Generally, The behavior of a function's graph at the "ends" of the x-axis is referred to as the function's "end behavior," and it is described by the symbol f. To put it another way, the trend of the graph may be described by the end behavior of a function if we look to the right end of the x-axis (as x approaches +) and to the left end of the x-axis (as x approaches ).

Take a look at the leading term of the polynomial function to get an idea of how it will behave in the end.

Because the power of the leading term is more than that of the other terms, whether x is made extremely big or very tiny, the leading term's behavior will predominate the graph because it will increase substantially quicker than the growth of the other terms.
