This is an exponential expression with 10 as the base and 4 as the exponent.
=============================================
Explanation:
We're dividing 10^8 over 10^4. When dividing like this, we subtract the exponents (numerator minus denominator). The bases must be the same value and they stay at the same value for the final answer as well.
The new exponent is 8-4 = 4 which is how we arrive at the answer 10^4.
Side note: 10^4 = 10,000 = ten thousand

What is the value of the expression 6 +5. (8 + 2)²?
The value of the expression 6 +5. (8 + 2)² is 506 after solving with BODMAS rule.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
We have an epression:
= 6 +5. (8 + 2)²
We can solve the above expression by BODMAS:
= 6 + 5(10)²
= 6 + 5(100)
= 6 + 500
= 506
Thus, the value of the expression 6 +5. (8 + 2)² is 506 after solving with BODMAS rule.

given that 4x^2-32x-20+k is a perfect square find k
Answer:
k = 20Step-by-step explanation:
Perfect square identity:
(a + b)² = a² + 2ab + b²Completing the square:
4x² - 32x - 20 + k = (2x)² - 2*2x*8 + 8² - 20 + k =(2x - 8)² - (20 - k)In order the given to be a perfect square, we need:

Multiply 6/5 by the reciprocal of (-3/8)
Answer:
-48/15, simplified to -16/5
Step-by-step explanation:
The reciprocal of -3/8 is -8/3. So the equation will be 6/5 x -8/3. Multiply numerators then multiply denominators to get -48/15. This can simplify to -16/5 by dividing both by 3.
Answer:
Step-by-step explanation:
hello :
6/5 by the reciprocal of (-3/8) means : ( 6/5 )(-8/3) = - 48/15 = -16/5

Y=-0.37x^2+6.15x+52.3 approximates the average temperature in October in degrees Fahrenheit at an agricultural community x hours after 5 a.m.
What is the best estimate for the average temperature in October at 2 p.m.?
64 F
67 F
71 F
78 F
Answer:
best approximate is 78 F. to find x, count number of hours between 5 am and 2 pm (which is 9). Substitute 9 into the equation and solve. hope this helps!
Step-by-step explanation:
[tex]y = - 0.37 {x}^{2} + 6.15x + 52.3 \\ y = - 0.37 ({9}^{2} ) + 6.15(9) + 52.3 \\ y = - 0.37(81) + 6.15(9) + 52.3 \\ y = - 29.97 + 55.35 + 52.3 \\ y = 77.68[/tex]

Remark
The position of these two angles is called vertically opposite. Every time two lines cross like this, you get vertically opposite angles. The point is that vertically opposite angles are equal.
x + 5= 46 Subtract 5 from both sides
x + 5-5 = 46-5
x = 41

Step-by-step explanation:
please make me a happy with brainleist answer
The value of its current stock is $3600 if the graphic design works use LIFO, and it has 400 T-shirts left in its inventory option (A) is correct.
What is LIFO?Last in, first-out (LIFO) is an inventory valuation approach based on the principle that the first asset sold is the most recent asset received.
We have data shown in the table:
Total number of T-shirts = 200+300+400+300 = 1200
As there are only 400 T-shirts left it means,
So (1200-400)800 T-shirts sold out according to LIFO last month T-shirt sold out.
200 T-shirts left in the June stock
Out of 300, there are 200 T-shirts left in the month of July.
Cost for 200 T-shirts = 200×8 = $1600
Cost for 200 T-shirts = 200×10 = $2000
Total cost = 1600+2000
= $3600
Thus, the value of its current stock is $3600 if the graphic design works use LIFO, and it has 400 T-shirts left in its inventory.

The area of trapezium shaped field is 480 square meter, the distance between two parallel sides is 15m and one of the parallel side is 20m. Find the other parallel side
Answer: 44 m
Step-by-step explanation:
Given
The area of the trapezium is [tex]A=480\ m^2[/tex]
Distance between parallel sides [tex]h=15\ m[/tex]
One of the parallel sides is [tex]20\ m[/tex]
Suppose the other parallel side is [tex]x[/tex]
The area of the trapezium is
[tex]A=\dfrac{1}{2}\times [\text{Sum of parallel sides}]\times h[/tex]
Put values
[tex]\Rightarrow 480=\dfrac{1}{2}\times [20+x]\times 15\\\\\Rightarrow 480\times 2=300+15x\\\Rightarrow 960-300=15x\\\Rightarrow x=44\ m[/tex]

Answer:
y ≤ 66.28 -> -∞
Step-by-step explanation:
y = a (x-h)² + k ... (h,k): vertex
y = - 32x² + 90x + 3
= -32 (x² - (90/32)x + (90/64)²) + (3 + (32)*(90/64)²)
= -32 (x² - 2*(90/64)x + (90/64)²) + (3+63.28) ... 90/64=1.41
= -32 (x - 1.41)² + 66.28
h = 1.41
k = 66.28 .... extremum of y value
y ≤ 66.28 (y is real number)
