Mathematics
1 answer:
LenaWriter [7]3 years ago
7 0

Answer:

Step-by-step explanation:

because -3 is a zero, so x=-3

(k-1)(-3)²+k(-3)+1=0

9(k-1)-3k+1=0

9k-9-3k+1=0

6k=8

3k=4

k=4/3

(B)

∵ x=-1 is a zero of p(x)=kx²-4x+k

so k(-1)²-4(-1)+(-1)=0

k+4-1=0

k=-3

Natasha_Volkova [10]

Answer:

If the soccer coach wants to know how many students made 15 or more goals then she should use the histogram because it is split in to different ranges so it’s easy for her to know how many students made 15 or more goals. If the soccer coach wants to know the least number of goals made she should use the dot plot because that shows the specific number of goals each student made while the histogram only gives an range.

(WILL GIVE BRAINLIEST) Describe how you would simplify the given expression.
Vinil7 [7]

Answer:

Simplify inside the parentheses by dividing coefficients, subtracting the exponents on like bases, and raising the resulting expression to the –3 power. Then, write bases with positive exponents.

Raise the numerator and denominator to the –3 power. Then, using the power of a power property, multiply the exponents. Divide the coefficients and subtract the exponents on like bases, then write with positive exponents.

Help plweaseeeee thanks ​
Sedaia [141]

Answer:

first triangle (to left) b=8, second one c=17

Step-by-step explanation:

for the first triangle (one to the left) the hypotenuse is 9, so let's use the pythagorean formula.

A^2   +  B^2  = C^2

^              ^          ^

^              ^         Hypotenuse

^        second side

first side

Substitute:

5^2 + b^2 = 9^2

SImplify:

25+b^2 = 81

Reduce:

b^2 = 64

Simplify:

b=8

In the second triangle, we are given 2 sides.

Let's do the same thing we did in the first one.

Givens:

A = 8

B = 15

Find:

C

Substitute:

8^2 + 15^2 = c^2

Simplify

64 + 225 = c^2

Reduce:

289 = c^2

Let's now square root both sides

square root of 289 is 17

so we are left with this:

c=17

Phew, you did it!

Hope this helped :))

Write the equation of the following line in slope-intercept form
sukhopar [10]

Answer:

y = 2/5x + 4

Step-by-step explanation:

Points on the line:

(0,4) and (5,6)

Slope formula:

m=(y2-y1)/(x2-x1)

m=(6-4)/(5-0)

m= 2/5

y - y1 = m(x - x1)

y - 4 = 2/5(x - 0)

y - 4 = 2/5x

y = 2/5x + 4
