Answer:

SC = 14 units

Explanation:

Centroid of a triangle refers to the point where it's 3 median intersect. It's the centre point of the triangle.

the point of intersection divides all three median into two parts. the parts are in ratio 2 : 1. The part of the median starting from the vertex to the midpoint is 2/3rd of the median.

SD = 21

SC = 2/3 of 21

= 2/3 × 21

= 14

Answer:

  • SC = 14

Step-by-step explanation:

Point C is the centroid.

Property of centroid: the medians are divided in 2:1 ratio from the vertices.

  • SD = 21
  • SC = 2/3*21 = 14

What is the measure of angle A, in degrees?​
juin [17]
96°.

Since sides AB and AC ane equal, that means that angle B is equal to angle C. The measurement of all the angles of a triangle always equals 180°, so if you add angles B and C, you should get 84° and then you should be able to find angle A. Subtract 84° from 180° and you should get 96°.

Which value of a in the exponential function below would cause the function to shrink? f(x) = a(three-halves) Superscript x Four
Natalka [10]

Answer:

Four-fifths

Step-by-step explanation:

As we know that

By multiplying the function by a constant, we may expand or shrink the function in the y-direction.

Now we have

y=a(b^{x})

if a> 1  > the function would enlarge

if 0< a < 1 > the function would shrinks

Now

For case A

a = \frac{4}{5}

0 < (\frac{4}{5} )< 1 ....... > the function would shrinks

For case B

a = \frac{5}{4}

(\frac{5}{4} )>1 .......> the function would enlarge

For case C

a = \frac{3}{2}

(\frac{3}{2} )>1 .........> the function would enlarge

For case D

a = \frac{7}{4}

(\frac{7}{4} )>1 .........> the function would enlarge

Therefore the second option is correct
