Multiply or divide
(K²) (k)
Algebra
For example, (x)(x)=x^2
Add the exponents of the variable to get the correct answer.
(k^3)(k^5)=k^8
Answer and Step-by-step explanation:
When two values have the same base, have exponents, and are being multiplied to each other, then we add together the exponents.
So, we are given k to the power of 3, which is multiplied by k to the power of 5. The powers (exponents) are added together to make 8, and the bases combine to be only one of the bases, being k.
So, we are left with the answer being [tex]k^8[/tex].
I hope this helps!

I need to find the value of x. I also need to show my work so if anyone answers this I need to know what the work is. Thank you!
Answer:
x = 8
Step-by-step explanation:
Given a tangent and a secant from an external point to the circle, then
The square of the tangent is equal to the product of the secants external part and the whole secant, that is
x² = 4(4 + 12) = 4 × 16 = 64 ( take the square root of both sides )
x = [tex]\sqrt{64}[/tex] = 8
I need help with this question
Answer:
O = 41 degrees
Step-by-step explanation:
the sum of all angles in a triangle is always 180 degrees.
the graphic shows that this triangle has 2 equal sides. that means that both angles at O and at M are equal.
so, we know all three angles and can calculate
7y + 2×(4y - 15) = 180
7y + 8y - 30 = 180
15y = 210
y = 14
so, the angle at O is
O = 4×14 -15 = 56 - 15 = 41 degrees

help finding the volume
Answer:
1651.06 m³
Step-by-step explanation:
the volume of the whole block is base area times height :
Vb = 10 × 12 × 18
but we have to deduct the volume of the removed central cylinder.
the volume of the cylinder is again base area times height :
Vc = pi×r² × 18 = pi×3² × 18 = pi×9×18
so, the volume of the object is
V = Vb - Vc = 2160 - 508.94 = 1651.06 m³
Your cousin Pablo gets his haircut, and it costs $12.00. What will he spend in total on his haircut if he includes a 12% tip?
Answer:
The tip would be $1.44, so the total would be $13.44
Step-by-step explanation:
To find the tip you take the bill ($12), and multiply it by the percent of tip given (12%), but it has to be in decimal form. 12% in decimal form is .12. 12 times .12 is 1.44. Add $12 to that to get $13.44.
Answer:
Step-by-step explanation:
You could do this a couple of ways. The first and easiest is to change 12% to a decimal. 12% = 12/100 = 0.12
Add this onto 1.
1 + 0.12 = 1.12
Multiply this number by
12*1.12 = 12(1 +0.12) Remove the brackets
12*1 + 1.44
Haircut + tip = 13.44
Of course, it would be much shorter to do it 12*1.12 = 13.44
What is the answer? i cant find it helpp
Answer:
The y intercept is 4
Step-by-step explanation:
The slope is
m= (y2-y1)/(x2-x1)
= (64-44)/(24-16)
= 20/8
For each increase of 8 we go up 20
So for each decrease of 8 we go down 20
(16,44)
(16-8, 44-20)
(8,24)
(8-8,24-20)
(0,4)
The y intercept is 4

Javed is building a birdhouse in the shape of a triangular pyramid. He drew the net for his birdhouse and labeled the dimensions. The base is an isosceles triangle with two side lengths of 20 cm. How much wood will Javed need for the birdhouse?
Answer:
See attachment
Step-by-step explanation:
Required
How much wood needed (i.e. the surface area)
The question is incomplete, as the net of the triangular prism is not given. So, I will answer with the attached net.
To calculate the surface area, we simply calculate the area of each face of the net.
The area of the net is as follows:
Area= 2 * Area of Triangle + 2 * Area of 2 Congruent Rectangles + Area of the third rectangle
So, we have:
[tex]Area = 2 * \frac{1}{2} * 6 * 5 + 2 * 8 * 7 + 8 * 6[/tex]
[tex]Area = 30 + 112 + 48[/tex]
[tex]Area = 190cm^2[/tex]

if (a/b) =(9/7)^-3 ÷(3/7)^1, then find the value of (a/b)^2
Answer:
decimal = 1.20527
Step-by-step explanation:
[tex]\frac{a}{b} = (\frac{9}{7})^{-3} \div (\frac{3}{7})^1[/tex]
[tex]=(\frac{7}{9})^3 \times \frac{7}{3}\\\\[/tex]
[tex](\frac{a}{b})^2 = ((\frac{7}{9})^3)^2 \times (\frac{7}{3})^2\\\\[/tex]
[tex]= \frac{7^6 \times 7^2}{9^6 \times 3^2}\\\\= \frac{7^8}{9^6 \times 9}\\\\=\frac{7^8}{9^7}\\\\=\frac{7^7 \times 7}{9^7}\\\\= 7 \times \frac{7^7}{9^7}\\\\= 7 \times (\frac{7}{9})^7[/tex]
[tex]=\frac{5764801}{4782969}[/tex]

#hopeithelpsstay safe and keep wellmark me as brain liest plsQuandrilateral ABCD is inscribed in a circle. What is the measure of angle A? A=(2x-40)B 116 C D=x what is the measure of angle A
Answer:
angle A = 88°
Step-by-step explanation:
Given: inscribed quadrilateral ABCD
(recall that inscribed quadrilaterals have opposite angles supplementary.
A=2x-40
B=116
D=x
From inscribed quadrilateral,
B+D=180 => 116+x = 180 => x=64
A=(2x-40) = 2*64-40 = 88°
(C = 180-88 = 92°)
