Q.23 Prove that: (sin4A - cos4A + 1) = 2sin2A
Answer:
Step-by-step explanation:
I think you have the question incomplete, and that this is the complete question
sin^4a + cos^4a = 1 - 2sin^2a.cos^2a
To do this, we can start my mirroring the equation.
x² + y² = (x + y)² - 2xy,
This helps us break down the power from 4 to 2, so that we have
(sin²a)² + (cos²a)² = (sin²a + cos²a) ² - 2(sin²a) (cos²a)
Recall from identity that
Sin²Φ + cos²Φ = 1, so therefore
(sin²a)² + (cos²a)² = 1² - 2(sin²a) (cos²a)
On expanding the power and the brackets, we find that we have the equation proved.
sin^4a + cos^4a = 1 - 2sin^2a.cos^2a
The freshman basketball coach’s office has a doorway that is 77 inches high. The coach will only recruit those student athletes who have to duck to enter the office. Of all the freshmen who wish to play basketball, the mean height is 75 inches with a standard deviation of 2.82 inches. Meanwhile, the football coach will only recruit student athletes to play linebacker (a defensive position) who weigh 210 pounds or more. Of all the freshmen who wish to play linebacker, the mean weight is 190 inches with a standard deviation of 12.32 pounds. Who do you think will have a harder time recruiting players?

Step-by-step explanation:
A population of 50 deer are introduced into a wildlife sanctuary. It is estimated that the sanctuary can sustain up to 500 deer. Absent constraints, the population would grow by 40% per year.
Estimate the population after one year
p1 =
Estimate the population after two years
p2=
Answer:
p1 = 70 deer
p2 = 98 deer
Step-by-step explanation:
We use the population growth expression:
[tex]N(t)=N_0\,(1+r)^t[/tex]
which in our case renders:
[tex]N(t)=N_0\,(1+r)^t\\N(t)=50\,(1+0.4) ^t\\N(t)=50\,(1.4) ^t[/tex]
Therefore, after 1 year the population would be:
[tex]N(1)=50\,(1.4) ^1=70[/tex]
giving a total of 70 deer
and after two years, it would be:
[tex]N(2)=50\,(1.4) ^2=98[/tex]

Answer: -3x
Step-by-step explanation: If you separate out each term on its own, 9 and x², and do the square root of each one, you are left with 3x. This is also coincidentally what the right side of this graph looks graphically. However, the line of 3x does continue past x=0, so the other side of this graph, -3x, fits this better.

Which box has a volume of 125 cubic feet?
4 feet
9 feet
5 feet
4 feet
3 feet
4 feet
5 feet
12 feet
2 feet
5 feet
5 feet
5 feet
Answer: Bottom left
5x5x5=125
The volume having 125 cubic, is a box which has dimensions, 5 feet, 5 feet, 5 feet. So Option D is correct
What is Volume?In mathematics, Space occupied by three dimensional objects is called Volume. Basically it is a space within a closed region of every three dimensional object.
Given that,
4 boxes having different different dimensions
1. 4 feet, 9 feet, 5 feet
2. 4 feet, 3 feet, 4 feet
3. 5 feet, 12 feet, 2 feet
4. 5 feet, 5 feet, 5 feet
lets calculate the volume for all the four boxes
V = 4 feet × 9 feet × 5 feet = 180 feet³
V = 4 feet × 3 feet × 4 feet = 48 feet³
V = 5 feet × 12 feet × 2 feet = 120 feet³
V = 5 feet × 5 feet × 5 feet = 125 feet³
Hence, the volume of box having dimension 5 feet, 5 feet, 5 feet is 125 feet³

-5x + y = -6
7x + 2y = 39
Answer:
x=3, y=9
Step-by-step explanation:
Mulriplying the first equation by 2 yields -10x+2y=-12.
Subtracting the second equation from this gives -17x=-51, and thus x=3.
Substituting this back into the first equation gives -15+y=-6, and thus y=9.

Which of the binomials below is a factor of this trinomial?
4x² + 12x + 9
The factor of the equation 4x² + 12x + 9 is 2x+3. Then the correct option is A.
What is a quadratic equation?It is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is 2.
The factor of the polynomial is calculated as:-
4x² + 12x + 9 = 4x² + 6x + 6x + 9
= 2x ( 2x + 3 ) + 3 ( 2x + 3 )
= (2x + 3)(2x + 3)
The factor is (2x + 3). Hence, the correct option is A.

C) 3
D) 2
Answer: B) 18
Step-by-step explanation: It is also widely used for predicting the value of one dependent variable from the values of two or more independent variables. When there are two or more independent variables, it is called multiple regression
The number of independent variables or predictors present in the regression model is 3.
The number of independent variables can be obtained from an ANOVA table of the degree of freedom column of corresponding to RegressionThe Regression degree of Freedom usually denoted as k - 1 ; where k is the number of independent variables. From the ANOVA table given ; k - 1 = 2 The value of k = 2 + 1 = 3 ; Therefore, the value of k in the regression table is 3.Therefore, the number of predictors in the regression is 3.

3/4 of girls in sss1 play basketball and 4/7 play volleyball. Every girl plays at least one of these games. if 27 play both games how many girls are in the class
Answer:
84
Step-by-step explanation:
1/4 of class don't play basketball but do play volleyball
so 9/28 of class play both since 4/7 - 1/4 = 9/28
9/28 of class = 27
1/28 of class = 3
class = 3*28
There are 84 girls in the class.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Girls who plays basketball = (3/4)x
Girls who plays volleyball = (4/7)x
Girls who plays both games = 27
Now, Let us consider total girls in the class = x
So we can write it as mathematical equation as;
⇒ (3/4)x +(4/7)x - 27 = x
By taking L.C.M. -
⇒ (21x+16x)/28 - (27) = x
⇒ 37x/28 = x + 27
⇒ 37x = 28x + (27×28)
⇒ 9x = 27×28
⇒ x = (27×28)/9
⇒ x = 3×28
⇒ x = 84
So, There are total 84 girls in the class.
