Calculate the value for each determinant:
Answer:
See explanations below
Step-by-step explanation:
Example of how to find the determinant of a 2×2 matrices is as shown;
[tex]\left[\begin{array}{ccc}a&b\\c&d&\end{array}\right][/tex]
= (a*d)-(b*c)
= ad - bc
Applying this to solve the given questions
1) (3*4) - (-3*-1)
= 12 - (3)
= 9
2) (-12*5)-(-1*12)
= -60 - (-12)
= -60+12
= -48
3) (0*4)-(-1*17)
= 0-(-17)
= 0+17
= 17
4) (8*-1)-(-4*-1)
= -8-(4)
= -8-4
= -12
5) (2*-1)-(2*-1)
= -2-(-2)
= -2+2
= 0
6) 1(1) - 0(0)
= 1 - 0
= 1

Answer:
D) [tex](x-4.5 )^{2} =16.25[/tex]
Step-by-step explanation:
Explanation
Given that the equation
x² - 9 x +11 =7
[tex]x^{2} -\frac{9}{2} (2x) +11=7[/tex]
[tex]x^{2} -\frac{9}{2} (2x) +(\frac{9}{2} )^{2} -(\frac{9}{2}) ^{2}+ 11=7[/tex]
By using (a-b)² = a²-2ab+b²
[tex](x-\frac{9}{2} )^{2} -(\frac{9}{2}) ^{2}+ 11=7[/tex]
[tex](x-\frac{9}{2} )^{2} -(\frac{9}{2}) ^{2}+ 11-7=0[/tex]
[tex](x-\frac{9}{2} )^{2} -(\frac{81}{4}) + 4=0[/tex]
[tex](x-\frac{9}{2} )^{2} +(\frac{-81+16}{4}) =0[/tex]
[tex](x-4.5 )^{2} -16.25 =0[/tex]
Final answer:-
[tex](x-4.5 )^{2} =16.25[/tex]

if £1 = 0.864 Lt, work out the amount, to the nearest penny , that 1 Lt is worth
Answer:
[tex]1\ Lt = \pounds 1.157[/tex]
Step-by-step explanation:
Given
[tex]\pounds 1 = 0.864\ Lt[/tex]
Required
Determine the worth of 1 Lt
[tex]\pounds 1 = 0.864\ Lt[/tex]
Divide both sides by 0.864
[tex]\pounds \frac{1}{0.864} = \frac{0.864}{0.864}\ Lt[/tex]
[tex]\pounds \frac{1}{0.864} = 1\ Lt[/tex]
[tex]1\ Lt = \pounds \frac{1}{0.864}[/tex]
[tex]1\ Lt = \pounds 1.157[/tex] -- approximated

a. Renard let’s t= the number of taffy bags and c= the number of Carmel bags. Help him write two equations to represent the information in the problem.
b. Now are are is stuck. He says, “if both of the equations were in the form ‘t= something’, I could set the two expressions equal to each other to find the solution.” Help him rewrite the equations into a form he can use to solve the problem.
c. Solve Renard’s system of equations to find the number of bags of Carmel and number of bags of taffy that Ariel bought.
d. How you can verify that your solution is correct?
Answer:
20 taffy bags and 15 caramel candy bagsStep-by-step explanation:
Given:
t = the number of taffy bagsc = the number of caramel bagsNumber of taffy's are 5 more than caramel bagsTaffy bags weigh 8 ounces and caramel bags weigh 16 ouncesTotal weight is 400 ouncesEquations:
t = c + 5 (the difference in number of bags)8t + 16c = 400 (the weight of the bags)Simplify the second equation by dividing all terms by 8:
t + 2c = 50Substitute t and solve for c:
c + 5 + 2c = 503c = 50 - 53c = 45c = 45/3c = 15Find the value of t:
t = 15 + 5 = 20Answer:

find the maximum and minimum values of the function y=1/2 sin2x
Answer:
Maximum value equals 1/2
Minimum value equals -1/2
Step-by-step explanation:
The Sin Function when Graphed Shows a Range of [-1 , 1]
apply that on y=1/2 sin2x
y = 1/2 * 1 = 1
y = 1/2 * -1 = -1
so y = 1/2 , -1/2 .
Another Method using 1st derivativedy/dx = 2 * 1/2 * cos2x
put dy/dx=0
cos2x=0
x= 45, x=135
Apply x values on y=1/2 sin2x
y = 1/2 , -1/2 .
Hope you understand it ^^.

Please help me solve and explain these two questions:
1. Find f'(x) for f(x) = ln(x^2 + e^(3x))
2. Find dy/dx by implicit differentiation for ysin(x) = xsin(y)
Answer:
go by basics u will get it easier
Step-by-step explanation:
assume X2 + e3x as some function t
now find derivative you get (1/t )dt/dx
now find dt /dx. simply derivative with respect to x
for second question use formula
dy/dx = - partial derivative of function with x / partial derivative of function with respect to y
THERE ARE 7 CONSECUTIVE NUMBERS.
IF THE LARGEST NUMBER 15 99, WHAT
IS THE SUM OF ALL THE GIVEN NUMBENS.
Answer:
S₇ = 672
Step-by-step explanation:
If there are 7 consecutive numbers and the largest is 99, then there are 6 smaller consecutive numbers:
Smallest number = 99-6 = 93
The sequence is 93, 94, 95, 96, 97, 98, 99.
Where:
a₁ = 93
an = 99
n = 7
Sum of the sequence:
Sn = n/2(a₁ + an)
S₇ = 7/2 (93 + 99)
S₇ = 7/2 (192)
S₇ = 7(96)
S₇ = 672
- 6 + \sqrt{9 - 8a} = 1−6+
9−8a
=1
Answer:
[tex]a = -5[/tex]
Step-by-step explanation:
Given
[tex]- 6 + \sqrt{9 - 8a} = 1[/tex]
Required
Solve for a
[tex]- 6 + \sqrt{9 - 8a} = 1[/tex]
Add 6 to both sides
[tex]6- 6 + \sqrt{9 - 8a} = 1+6[/tex]
[tex]\sqrt{9 - 8a} = 7[/tex]
Square both sides
[tex]( \sqrt{9 - 8a})^2 = 7^2[/tex]
[tex]9 - 8a = 49[/tex]
Subtract 9 from both sides
[tex]9-9 - 8a = 49-9[/tex]
[tex]- 8a = 40[/tex]
Make a the subject
[tex]a = -\frac{40}{8}[/tex]
[tex]a = -5[/tex]

Greta currently works 45 hours per week and earns a weekly salary of $729. She
will soon be starting a new job where her salary will be increased by 10% and her
hours reduced by 10%.
How much more will she be earning per hour at her new job?
Answer:
Step-by-step explanation:
current rate = $729/(45 hours) = $16.20/hour
increased salary = 1.10×$729 = $801.90
decreased hours = 0.90×45 = 40.5
increased rate = $801.90/(40.5 hours) = $19.80/hour
increase in rate = $19.80/hour - $16.20/hour = $3.60/hour
