How long would the straw be?
Answer:
Length of straw = 11 inch (Approx.)
Step-by-step explanation:
Given:
Length of cuboid = 9 inch
Width of cuboid = 5 inch
Height of cuboid = 4 inch
Find;
Length of straw
Computation:
Length of straw = Diagonal of cuboid
Diagonal of cuboid = √l² + b² + h²
Diagonal of cuboid = √9² + 5² + 4²
Diagonal of cuboid = √81 + 25 + 16
Diagonal of cuboid = √122
Diagonal of cuboid = 11.04
Length of straw = 11 inch (Approx.)

The function f is given by f(x)= (x-2) (x+4) . Without using graphing technology, answer the following questions. (graph included)
1) What are the x-intercepts of the graph representing f?
2) What are the x- and y-coordinates of the vertex of the graph?
please help!!
Answer:
x-intercepts = -4 and 2
vertex (-1, -9)
Step-by-step explanation:
To find the x-intercepts ie roots
set the equation to 0
(x - 2) (x + 4) = 0
From the zero product rule
x - 2 = 0
x = 2
x + 4 = 0
x = -4
x-intercepts = -4 and 2
--------------------------
The x coordinate of the vertex is the midpoint of the roots
x = (-4 + 2)/2
x = -1
Plug x = -1 into the function
y = (-1 - 2)(-1 + 4)
y = -3 * 3
y = -9
vertex (-1, -9)

If R is inversely proportional to A, and R = 4 when A = 100, what is the value of R when A = 250 A : .625 B : 1.6 C : 10 D : 6,250
Answer: (b)
Step-by-step explanation:
Given
R is inversely proportional to A i.e
[tex]R\propto \dfrac{1}{A}\\\\R=\dfrac{C}{A}\quad [\text{C=Constant}][/tex]
when [tex]R=4,\ A=100[/tex]
Insert the values to get C
[tex]\Rightarrow 4=\dfrac{C}{100}\\\\\Rightarrow C=400[/tex]
When A=250
[tex]\Rightarrow R=\dfrac{400}{250}\\\\\Rightarrow R=1.6[/tex]
option (b) is correct
Jessica went shopping for a new watch. She found a watch that was originally priced at $50 on sale for $40. By what percent had the watch been marked down?
Answer:
20%
Step-by-step explanation:
We were given a price at $50 on sale for $40. To get the markdown percentage, take the amount of money you've discounted the merchandise at and divide it by the sales price.
$50 sweaters, you can put them on sale for $40.
[tex]50 - 40 = 10[/tex]
The difference between these two prices is $10.
Now, we need to add the amount of which it was marked down
[tex]10 + 10 = 20[/tex]
Therefore, the watch has been marked down by 20%.

Diego was trying to write 2^3 · 2^2 with a single exponent and wrote 2^3·2^2 = 2^3*2 = 2^6 . Explain to Diego what his mistake was and what the answer should be.
Answer:
2^3·2^2 = 2^3+2 = 2^5
Step-by-step explanation:
Diego was trying to write 2^3 · 2^2
He wrote 2^3·2^2 = 2^3*2 = 2^6
But this is wrong because when bases are same exponents are added.
This is the law of exponents.
The correct form would be
2^3·2^2 = 2^3+2 = 2^5
For understanding it better we can write it like this
2^3·2^2 =

Coordinate plane with no numbers marking the units. A circle is drawn on the plane, with the center at the labeled point begin ordere pair 0 comma negative 3 end ordered pair. The perimeter of the circle goes through the labeled point begin ordered pair negative 3 comma negative 3 end ordered pair.
Answer:
Step-by-step explanation:
Equation for a circle of radius r, centered at (h,k):
(x-h)² + (y-k)² = r²
x² + (y+3)² = 9 is the equation for a circle of radius 3, centered at (0,-3).
Option D - Coordinate plane with no numbers marking the units. A circle is drawn on the plane, with the center at the labeled point begin ordered pair 0 comma negative 3 end ordered pair. The perimeter of the circle goes through the labeled point begin ordered pair negative 3 comma negative 3 end ordered pair IS CORRECT.
We have a equation of circle -
[tex]x^{2} +(y+3)^{2} = 9[/tex]
We have to find out which statement correctly represents the graph of this equation.
What is the general equation of circle?The general equation of the circle with radius r and center at (h, k)
is - [tex](x-h)^{2} +(y-k)^{2} =r^{2}[/tex]
The equation given to us is -
[tex]x^{2} +(y+3)^{2} = 9[/tex]
On comparing it with the general equation of the circle, we get -
[tex]x-h=x\\h=0\\\\y-k=y+3\\k=-3\\\\r^{2} =9\\r=3[/tex]
Therefore, we have a circle whose center lies at (0, -3) with radius = 3 units.
At point P(3, 3) -
[tex](-3)^{2}+(-3+3)^{2} =9\\9=9[/tex]
Hence, Option D - coordinate plane with no numbers marking the units. A circle is drawn on the plane, with the center at the labeled point begin ordered pair 0 comma negative 3 end ordered pair. The perimeter of the circle goes through the labeled point begin ordered pair negative 3 comma negative 3 end ordered pair is correct.

Answer:

Step-by-step explanation:
you add the exponents together when there are parentheses
Answer:
B
Step-by-step explanation:
When raising a number to a power, to another power, you can multiply the exponents. Think of (6^3)^2 as (6*6*6)^2. (6*6*6)^2 is equal to (6*6*6)*(6*6*6). This is the same as 6^6.
10) Calculate angle u, v and w
A
Y
с
88
68
Answer:
u = 24, v = 92, and w = 184
Step-by-step explanation:
According to circle theorem, we have;
∠ACD = ∠ABD = 88° by angle inscribed in a circle and also subtending the same chord
∠DOA = 2 × ∠ABD by angle subtended at the center = 2 × Angle subtended at the circumference
∴ ∠DOA = 2 × ∠ABD = 2 × 88° = 176°
w° + ∠DOA = 360 by the sum of angles at a point
∴ w° = 360° - ∠DOA = 360° - 176° = 184°
w° = 184°
w° = 2 × v° by angle subtended at the center = 2 × Angle subtended at the circumference
∴ v° = w°/2 = 184°/2 = 92°
v° = 92°
In triangle ΔCDY and ΔABY, we have;
∠ABD = ∠ABY by reflexive property
∠ACD = ∠ACY by reflexive property
∠ACD = ∠ABD = 88°
∴ ∠ABY = 88°
∠CYD = ∠AYB by vertically opposite angles are equal
∴ ∠CYD = 68° = ∠AYB
u° + ∠ABY + ∠AYB = 180° by angle sum property
∴ u° = 180° - (∠ABY + ∠AYB)
u° = 180° - (88° + 68°) = 24°
u° = 24°.
what is the area of the triangle 3,4,5
If the interest on a 4,600 loan is 370 what would be in the interest on a loan of 9.660
Answer:
772.17
Step-by-step explanation:
Given,
Interest (I) = 370
Principal (P) = 4600
Rate (R) = ? , Time (T) = ?
We know,
I = PTR/100
or, 370 = 4600TR/100
or, 370 = 46TR
∴ TR = 370/46 = 185/23.................(1)
Now,
On Principal (P) = 9600
Interest (I) = PTR/100
or, I = 9600TR/100
or, I = 96 * 185/23 (∵From 1)
∴ I = 772.179
