Answer:
[tex]|A| = - 28[/tex]
Step-by-step explanation:
Given
[tex]A = \left[\begin{array}{cc}-2&6\\3&5\end{array}\right][/tex]
Required
Determine the determinant
For a two by two matrix, A such that:
[tex]A = \left[\begin{array}{cc}a&b\\c&d\end{array}\right][/tex]
The determinant |A| is:
[tex]|A| = a * d - b * c[/tex]
So, in
[tex]A = \left[\begin{array}{cc}-2&6\\3&5\end{array}\right][/tex]
The determinant is:
[tex]|A| = -2 * 5 - 6 * 3[/tex]
[tex]|A| = -10 - 18[/tex]
[tex]|A| = - 28[/tex]

5 beetles out of 45 insects.
1:9 is the answer
Answer:
I suppose that this question is about ratios.
When we have A elements of one type, for every B elements of another type.
The ratio between these elements is A:B
In this particular case, we have:
5 beetles out of 45 insects (the 5 beetles do not belong to the group of 45 insects, if that where the case, we would not get the value 1:9 seen in the question)
Then there are 5 beetles and 45 insects.
The ratio is 5:45
Now, whit those we can divide both numbers by the same number and the ratio will be the same, then if we divide both by 5, we get:
(5/5):(45/5)
1:9

cake batter poured into a pan creates a circular batter pattern whose radius increases at a constant rate of 1 in/sec. at what rate is the total batter area increasing at the end of 4 second
Answer:
8 π .
Step-by-step explanation:
radius increases at a constant rate of 1 in/sec.
dr / dt = 1
where r is radius .
radius after 4 sec
r = 1 x 4 = 4 in
area A = π r²
differentiating both sides
dA / dt = 2 π r dr / dt
Putting dr / dt = 1 , r = 4 in
dA / dt = 2 π x 4 x 1
= 8 π sq in per sec.
Area increases at the rate of 8 π per sec.
Dan invests £18790 into his bank account. He receives 4.9% per year simple interest. How much will Dan have after 3 years?
Answer:
£21,552.13
Step-by-step explanation:
A = P(1 + rt)
P = £18790
r = 0.049 (rate in percent form)
t = 3 years
A = £18790(1 + (0.049)(3))
A = £18790(1 + 0.147)
A = £18790(1.147)
A = £21,552.13
Calculate the area of trapezium CDEF:)
In the diagram shown
. CDEF is a trapezium
.ABCF is a rectangle
. BD = 9cm
.AB = 6cm
.EF = 3cm
Perimeter of ABCF = 20cm
Answer:
6+6=12
20-12 = 8
8/2 = 4
BC = 4 cm
9 - 4 = 5
CD = 5
5 + 3 = 8
8/2 = 4
4 X 6 = 24

Y-intercept for y=2(x-3)^2+4
Answer:
The y-intercept for this equation is 22.
Step-by-step explanation:
You can solve this quite easily by assigning a zero value to x and solving for y. That is where the curve will intersect the x-axis:
y = 2(x - 3)² + 4
y = 2(x² - 6x + 9) + 4
y = 2x² - 12x + 18 + 4
y = 2x² - 12x + 22
EDIT
Note that the expression above is in standard form, though it can also be factored if needed:
y = 2(x² - 6x + 11)
Now we can solve for an x value of zero:
y = 2(0)² - 12(0) + 22
y = 22
So the y-intercept is 22.
