A rectangle is 8 cm long and 3.5 cm wide.
a) Calculate the area of the rectangle.
State the units of your answer.
Answer:
area = 28 cm²
Step-by-step explanation:
area = 8 x 3.5 = 28 cm²
Answer:
28 cm²
Step-by-step explanation:
Because the length of the rectangle is 8 and the width is 3.5 cm which we know we that the area is "length x width" so we should multiply both numbers getting 28 cm

If Theta is an angle in standard position and its terminal side passes through the point
(-8,9), find the exact value of tan theta in simplest radical form.
Answer: - 9/8
Step-by-step explanation:
using the balanced equation 4FE+3O2 --> 2fe2O3 calculate how many grams of Fe2O3 are produced when 42.7 grams of Fe is reacted
The coefficients in the balanced reaction
4 Fe + 3 O₂ → 2 Fe₂O₃
represent the ratio of moles of each reactant to each product. That is, for every 4 moles of Fe and 3 moles of O₂, 2 moles of Fe₂O₃ are produced.
First convert the given amount of Fe into moles. Fe has a molar mass of 55.845 g/mol, so you have
42.7 g × (1/55.845 mol/g) = 0.765 mol
of Fe.
Find how many moles of Fe₂O₃ are produced given this much Fe and an abundant supply of O₂. Multiply the coefficients of the balanced reaction by 0.765/4 :
0.765 Fe + 0.573 O₂ → 0.382 Fe₂O₃
Now convert the amount of Fe₂O₃ to grams. O has a molar mass of 15.999 g/mol, so Fe₂O₃ has a total molar mass of about
2 (55.845 g/mol) + 3 (15.999 g/mol) = 159.687 g/mol
Then the reaction would produce about
0.382 mol × (158.687 g/mol) ≈ 61.0 g
of Fe₂O₃.

What is the a-value of the quadratic

The drag Prevnar is a vaccine meant to prevent meningitis. It is typically administered to infants between 12 and 15 months of age. Of the 710 infants,121 experienced a loss of appetite. Is there significant evidence to conclude the proportion of infants who receive Prevnar and experience of a loss of appetite is different from 0.135, the proportion of children who experience a loss of appetite with competing medications? Use α=0.01 level of significance.
Answer:
The pvalue of the test is 0.0058 < 0.01, which means that there is significant evidence to conclude the proportion of infants who receive Prevnar and experience of a loss of appetite is different from 0.135.
Step-by-step explanation:
Test if the proportion of infants who receive Prevnar and experience of a loss of appetite is different from 0.135
This means that the null hypothesis is:
[tex]H_{0}: p = 0.135[/tex]
And the alternate hypothesis is:
[tex]H_{a}: p \neq 0.135[/tex]
The test statistic is:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.
0.135 is tested at the null hypothesis:
This means that [tex]\mu = 0.135, \sigma = \sqrt{0.135*0.865}[/tex]
Of the 710 infants,121 experienced a loss of appetite.
This means that [tex]n = 710, X = \frac{121}{710} = 0.1704[/tex]
Value of the test-statistic:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
[tex]z = \frac{0.1704 - 0.135}{\frac{\sqrt{0.135*0.865}}{\sqrt{710}}}[/tex]
[tex]z = 2.76[/tex]
Pvalue of the test and decision:
The pvalue of the test is the pobability that the population proportion differs from the tested proportion by at least 0.1704 - 0.135 = 0.0354, which is P(|z| > 2.76). This probability is 2 multiplied by the pvalue of z = -2.76.
Looking at the z-table, z = -2.76 has a pvalue of 0.0029
2*0.0029 = 0.0058
The pvalue of the test is 0.0058 < 0.01, which means that there is significant evidence to conclude the proportion of infants who receive Prevnar and experience of a loss of appetite is different from 0.135.

:
Rewriting the whole as an Equivalent Fraction
4.1 Subtracting a fraction from a whole
Rewrite the whole as a fraction using y as the denominator :
6y3 - 4y2 - 3y (6y3 - 4y2 - 3y) • y
6y3 - 4y2 - 3y = —————————————— = ————————————————————

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

:
Pulling out like terms
5.1 Pull out like factors :
6y3 - 4y2 - 3y = y • (6y2 - 4y - 3)
Trying to factor by splitting the middle term
5.2 Factoring 6y2 - 4y - 3
The first term is, 6y2 its coefficient is 6 .
The middle term is, -4y its coefficient is -4 .
The last term, "the constant", is -3
Step-1 : Multiply the coefficient of the first term by the constant 6 • -3 = -18
Step-2 : Find two factors of -18 whose sum equals the coefficient of the middle term, which is -4 .
-18 + 1 = -17
-9 + 2 = -7
-6 + 3 = -3
-3 + 6 = 3
-2 + 9 = 7
-1 + 18 = 17
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Adding fractions that have a common denominator :
5.3 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

Thoughtfully split the expression at hand into groups, each group having two terms :
Group 1: -3y2 - 6
Group 2: 6y4 - 4y3
Pull out from each group separately :
Group 1: (y2 + 2) • (-3)
Group 2: (3y - 2) • (2y3)
Bad news !! Factoring by pulling out fails :
The groups have no common factor and can not be added up to form a multiplication.

Polynomial Roots Calculator is a set of methods aimed at finding values of y for which F(y)=0
Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers y which can be expressed as the quotient of two integers
The Rational Root Theorem states that if a polynomial zeroes for a rational number P/Q then P is a factor of the Trailing Constant and Q is a factor of the Leading Coefficient
In this case, the Leading Coefficient is 6 and the Trailing Constant is -6.
The factor(s) are:
of the Leading Coefficient : 1,2 ,3 ,6
of the Trailing Constant : 1 ,2 ,3 ,6

Determine the area of the composite figure.
Determine the perimeter of the composite figure.
Add the half circle to the rectangle and subtract the triangle.
Area of half circle = 1/2 x pi x 8.5^2 = 113.4325
Area of rectangle = 11 x 17 = 187
Area of triangle: 1/2 x 3 x 17 = 25.5
Total area: 113.4325 + 187 - 25.5 = 274.9325 square m
Perimeter: outside dimension for 1/2 circle = 1/2 x 3.14 x 17 = 26.69
Perimeter = 26.69 + 11 + 11 + 9 + 9 = 66.69 m

In triangle NOP p equals 600 inches angle P equals 96° and angle N equals 64° what is the area of triangle NOP to the nearest 10th of a square inch?
9514 1404 393
Answer:
55,637.8 square inches
Step-by-step explanation:
We can find side n using the Law of Sines:
n/sin(N) = p/sin(P)
n = p(sin(N)/sin(P)) = 600·sin(64°)/sin(96°)
n ≈ 542.246913 . . . . inches
The angle O is ...
O = 180° -N -P = 180° -64° -96° = 20°
Then the area is ...
A = 1/2·np·sin(O)
A = (1/2)(542.246913 in)(600 in)·sin(20°) ≈ 55,637.81008 in²
The area of ∆NOP is about 55,637.8 in².

Answer:
In the first one you are missing (x - 3) so it will be 4(x - 3) and if you factor it out it will be 4x - 12
In the second one you are missing a (x -5)which means 9x(x -5) or when you factor it out it will be 9x^2 - 45x
Step-by-step explanation:
3x^2 -23x + 40 = (3x - 8) (x - 5)
3x^2 -17x + 24 = (3x -8) ( x - 3)
