Use PEMDAS to figure out the order of operations:

Parentheses
Exponents
Multiplication/Division
Addition/Subtraction

Solve (-4 + -6) first, as this is in parentheses:

-4 + -6 = -10

10 - 5.3 * -10

Solve 5.3 * -10 next, as this is multiplication:

5.3 * -10 = -53

10 - -53

Now we can solve the equation:

10 - -53 = 63

The answer is 63.

Parentheses
Exponents
Multiplication
Division
Addition
Subtraction

Parentheses is 1st

-4 + -6 = -10

Then is multiplication. 

-10 × 5.3 = -53

At last, subtract

10 - (-53) is the same as: 10 + 53

10 + 53 = 63

Your answer is 63

Hope this helps :)

The area bounded by the 2 parabolas is A(θ) = 1/2∫(r₂²- r₁²).dθ between limits θ = a,b... 

<span>the limits are solution to 3cosθ = 1+cosθ the points of intersection of curves. </span>
<span>2cosθ = 1 => θ = ±π/3 </span>

The sum of two numbers is 90. The larger
Jobisdone [24]

Answer:

Small number = 19

Larger no. = 3(19)+14 = 71

Step-by-step explanation:

x + 3x + 14 = 90

4x + 14 = 90

4x = 90 - 14

x = 76 / 4 = 19

Help on the second graph
Deffense [45]

Answer:

<u>first graph:</u>

function.

Not one-one

onto

<u>Second graph:</u>

Function

one-one

not onto.

Step-by-step explanation:

We know that a graph is a function if any vertical line parallel to the y-axis should intersect the curve exactly once.

A graph is one-one if any horizontal line parallel to the x-axis or domain should intersect the curve atmost once.

and it is onto if any horizontal line parallel to the domain should intersect the curve atleast once.

Hence, from the <u>first graph:</u>

if we draw a vertical line parallel to the y-axis then it will intersect the graph exactly once. Hence, the graph is a function.

But it is not one-one since any horizontal line parallel to the domain will intersect the curve more than once.

But it is onto, since any horizontal line parallel to the domain will intersect the curve atleast once.

<u>Second graph</u>

It is a function since any vertical line parallel to the co-domain will intersect the curve exactly once.

It is not one-one since any horizontal line parallel to the x-axis does not intersect the graph atmost once.

It is not onto, since any horizontal line parallel to the domain will not  intersect the curve atleast once.
