Answer:

Hence first graph is the correct answer.

T I

1 28

2 56

3 84

4 112

Step-by-step explanation:

Given that initial amount P = $400

Simple rate of interest = R = 7% = 0.07

Time t= 1,2,3,4 years.

Then apply Simple interest formula to find the total interest earned in the given years.

I=PRT

for t=1 year

I=PRT=400(0.07)(1)=28

for t=2 year

I=PRT=400(0.07)(2)=56

for t=3 year

I=PRT=400(0.07)(31)=84

for t=4 year

I=PRT=400(0.07)(4)=112

Now we have table as shown below:

T I

1 28

2 56

3 84

4 112

Graphing these points we see that obtained graph best matches with First choice .

Hence first graph is the correct answer.

AB is a diameter of a circle, center O. C is a point on the circumference of the circle, such that
Solnce55 [7]

Given:

AB is the diameter of a circle.

m∠CAB = 26°

To find:

The measure of m∠CBA.

Solution:

Angle formed in the diameter of a circle is always 90°.

⇒ m∠ACB = 90°

In triangle ACB,

Sum of the angles in the triangle = 180°

m∠CAB + m∠ACB + m∠CBA = 180°

26° + 90° + m∠CBA = 180°

116° + m∠CBA = 180°

Subtract 116° from both sides.

116° + m∠CBA - 116° = 180° - 116°

m∠CBA = 64°

The measure of m∠CBA is 64°.

Help please thank you
anzhelika [568]

Answer:

g(1) = -6

Step-by-step explanation:

g(x) = -2x^2 - 4x

You want to solve for g(1). To do this make every x value in the original equation become 1.

g(1) = -2(1)^2 - 4(1)

Evaluate the exponent.

g(1) = -2(1) - 4(1)

Multiply.

g(1) = -2 - 4

Subtract.

g(1) = -6

Consider the following function.
goldfiish [28.3K]
We have that
<span>f(x) = (3/2)*x + 4

case 1) for x=-8
</span>f(-8) = (3/2)*(-8) + 4--------> -8
point (-8,-8)

case 2) for x=-4
f(-4) = (3/2)*(-4) + 4--------> -2
point (-4,-2)

case 3) for x=-2
f(-2) = (3/2)*(-2) + 4--------> 1
point (-2,1)

case 4) for x=0
f(0) = (3/2)*(0) + 4--------> 4
point (0,4)

case 5) for x=2
f(2) = (3/2)*(2) + 4--------> 7
point (2,7)

case 6) for x=4
f(4) = (3/2)*(4) + 4--------> 10
point (4,10)
