Sketch the graph of y = negative 2 x squared + x + 1 using your graphing calculator. What are the x-intercepts of this graph? a. (1, 0) and (-0.5, 0) c. There are no x-intercepts b. (-2.5, 0) and (-2, 0) d. (-1.5, 0) and (-0.5, 0)

The correct answer is option D. which is the angle x will be 38 degrees.

The measure of the angle created when two chords collide inside a circle is one-half the sum of the arcs intercepted by the angle and its vertical angle.

Here we have a measure of arc AB = 58 and the measure of arc CD = 18, So what is the value of x?

The value of x will be calculated by using the angle of arc theorem.

x  =  Sum of the arcs / 2

x  = ( 58 + 18 ) / 2

x  = ( 38 degrees )

Therefore the correct answer is option D. which is the angle x will be 38 degrees.

Answer:

16

Step-by-step explanation:

the range is the amount of numbers between the highest and lowest number in a set.  if the lowest number is 3, and the range is thirteen, and the number must be a positice, the highest number in the range is 16.

The formula for calculating the amount predicted at t years is expressed as:

A = P(1+r)^t. The  predicted value after 2 years is £253.62

The formula for calculating the amount predicted at t years is expressed as:

A = P(1+r)^t

where

Substitute the given parameters

A = 240(1+0.028)^2
A =240 (1.028)^2

A = £253.62

Hence the  predicted value after 2 years is £253.62

A function assigns the value of each element of one set to the other specific element of another set.

The time at which the ball will hit the ground is,

h(t) = −16t² + 10t + 6

0 = -16t² + 10t + 6

8t² - 8t + 3t - 3= 0

8t(t-1)+3(t-1) = 0

(8t+3)(t-1)=0

t = -0.375, 1

Hence, the ball hit the ground at 1 second, while the function in intercept form can be written as h(t) = (−8t − 3)(2t − 2).

Answer:

  (b)  $6,769

Step-by-step explanation:

The value in the account can be found by using the compound interest formula:

  A = P(1 +r/n)^(nt)

where P is the principal invested, r is the annual rate, n is the number of times per year interest is compounded, and t is the number of years.

__

Using the given values in the formula, we have ...

  P = 5600, r = 0.019, n = 4, t = 10

  A = 5600(1 +0.019/4)^(4·10) = 5600×1.00475^40 ≈ 6768.752

The amount in the account at the end of 10 years was about $6,769.

Step-by-step explanation:

Supplementary angles add up to 180 degrees

So to find the measure of an angle supplementary to a given angle, we simply subtract the given angle from 180

The given angle here has a measure of 153 degrees

So the angle's supplement has a measure of 180 - 153 = 27 degrees.

     For both of these, we will divide the wanted outcome by the number of possible outcomes. We will end up with a decimal. A decimal multiplied by 100 becomes a percent.

[a] 50%

[tex]\displaystyle \frac{\text{wanted outcomes}}{\text{possible outcomes}} =\frac{\text{student failed}}{\text{Period 2's class}} =\frac{12}{24} =0.5,\:0.5*100=50\%[/tex]
